UAV Toolbox Support Package for PX4 Autopilots

Access PX4 autopilot peripherals with UAV Toolbox and automatically build and deploy flight control algorithms with Embedded Coder

128 Downloads

Updated 16 Sep 2020

Using the UAV Toolbox Support Package for PX4® Autopilots, you can access autopilot peripherals from MATLAB® and Simulink®. With Embedded Coder®, you can also automatically generate C++ code and use the PX4 toolchain to build and deploy algorithms tailored specifically for Pixhawk® and Pixracer flight management units (FMU), all while incorporating onboard sensor data and other PX4-specific services. PX4 is a trademark of Lorenz Meier.

Hi Rajesh Roy,

You can use a model developed in Simulink as the Simulator. Check the below links for more details and example
https://www.mathworks.com/help/supportpkg/px4/ug/integrate-plantmodel-simulator.html
https://www.mathworks.com/help/supportpkg/px4/ref/simulator-plant-model-example.html

We are working on enabling HITL with the support package and we will update it here when it is ready.

You can use the toolbox to develop your own controller and deploy it and fly your UAV. Several of our customers have done that.

Hello David Neal,
Thanks for reporting this issue. We are looking into it.

R

I discovered that the buzzer is not working anymore in the 2020b version. The buzzer activation threw uorb mssg tune_control) worked in 2020a but doesn't work anymore with the new rc.txt. Any one encountered/solved this problem?
As David Neal found , something is not complete with the new rc.txt.

David Neal

I found the problem. The rc.txt file does not include rc_input start. Apparently, that's supposed to be initiated by the default rCS but it wasn't. I copied rc_input start into the rc.txt file and the Radio Control Transmitter block started working. As I said, this was not an issue in 2020a.

David Neal

When I was using 2020a, the Radio Control Transmitter block was working fine. Now that I've updated to 2020b it's not working at all. Did something change in the rc.txt file so that the Pixracer is no longer reading the SBUS inputs? The status code is 1 from the block.

Jin woo Lee,
You can use the uORB blocks to subscribe or publish to any topic in the middleware. If your Simulink needs to communicate with any other model over the uORB bus, you can see the uORB blocks.

Hi Abhishek,
Except for jMavSim, can I use or has anyone tested this build using any other simulator? Can I do HITL using this? Is this toolbox gonna be a ready-to-fly for Pixhawk flight controller UAVs?

Hi Bert Vandewalle,

I tried running a model with a discrete integrator block in External-mode and it worked fine. Probably you should check the signal you are feeding to the integrator and see if it has NaN values at any timestamp.
If you are still facing the issue, I would encourage you to contact technical support (https://www.mathworks.com/support/contact_us.html).

Thank you, Mr. Angkur Boss.

And there's another question.
I want to create an environment that connects Pixhawk controllers with fixed-wing models that are based on simulink.
I wonder if you can use uORB blocks to configure these environments.

Ahmed Ashraf

Whenever i try an Example simulation on my Pixhawk 1 i get this error. Any fixes?

Error occurred while executing External Mode MEX-file 'ext_comm':
Unexpected response from target. Expected EXT_CONNECT_RESPONSE.
Component:Simulink | Category:Block diagram error
Unable to connect to the 'PX4 Pixhawk 1' target for 'px4demo_Read_Parameter'

Jinyu Yin,
The support for WSL to compile PX4 Firmware is now deprecated. We recommend you upgrade to R2020b and migrate to the Cygwin PX4 Toolchain in Windows.

Ankur Bose

Jin woo Lee,

I can see that you are using PX4 Firmware v1.8.0, however the the version of Cygwin Toolchain that you are using to compile the firmware is greater than 0.5 which is not supported by PX4 Firmware v1.8 as documented here. https://www.mathworks.com/help/releases/R2020a/supportpkg/px4/ug/setup-cygwin-toolchain.html

Please ensure that you have the correct Cygwin toolchain installed for your PX4 Firmware

Jinyu Yin

Hi everyone
I met a weird problem. After installling the toolbox, the configuration step forced me to install Ubuntu16.04LTS on WSL. However the window still pop out though I have installed the Ubuntu16.04LTS. It seems like there is a mechanism in the toolbox to detect the ubuntu installation however it does not work.
System:Windows10 professional
version:1903
system version 18362.1139

Jinyu Yin

wired->weird sorry for typo

Hi Mohammed Mohiuddin

You are all set with the PX4 setup. The message states that "The connection between the host computer and PX4 Autopilot board is successfully established." If you have established the communication, getting the accel data is optional. Sometimes there may be data drops during communication between autopilot and the PC - this varies from PC to PC. So I would go ahead using the PX4 Support package.

Thanks,
Amit

I built a simulation using uORB Read Block, and an error appears below.
Please help me.

Hi,

I've got a problem when trying to run controllers with an integrator on pixhawk. Checking the output of the discrete integrator blocks with "Monitor and Tune", show that they output NaN. I had this problem also for derivative blocks, but this was solved by initializing them with a non-zero value. This didn't work for the integrator blocks. When running the controller in SITL, there are no problems.

Any ideas on how to solve this? I'm using the Pixhawk 2.1 (Cube), PX4 Firmware v1.10.2 and Ubuntu 18.04

Abhishek GS

Hi Akihiro Mizutani,

After installing the support package, you can find the rc.txt by executing the below command in MATLAB.
>>cd (fullfile(codertarget.pixhawk.internal.getSpPkgRootDir,'lib','etc'))

Hi Rajesh,

SITL with AirSim is not supported with UAV Toolbox Support Package for PX4 Autopilots

Mohammed Mohiuddin

Hi
I started with the hardware setup and completed it without any issues until the last step where I had to click 'Get Accelerometer Data'. At that point, I get an error stating, "The connection between the host computer and PX4 Autopilot board is successfully established. However, the serial data received is corrupted. Try again by clicking Get Accelerometer data.".
I tried the solution suggested and when it still did not resolve, I redid the entire setup process, to no avail. Can you please help me solve my issue?

Rajesh Roy

Can I use SITL in AirSim using this?

Akihiro Mizutani

Hi. Where can I find rc.txt since if I do not have embedded coder toolbox?

Ankur Bose

Hello Rajesh Roy,
Please note that R2020b only supports PX4 Firmware v1.10.2. We have not tested with PX4 Firmware v1.11 and the features are not guaranteed to work.

Rajesh Roy

Hey Ankur Bose,
Thank you for your reply. I am using R2020b and firmware version 1.11 on Windows 10 machine.
The issue is resolved now. Basically the document is suppose to be updated as the new install of cygwin does not auto run the JMavSim while trying to build the firmware. I had to manually run the console bat file and then call for the SITL JMavSim. Now it's not a problem.
Just one concern, is there any relevant study tutorials or development group on Slack or somewhere to quickly discuss on the problem?

Ankur Bose

Hello Rajesh Roy,
Can you let us know a bit more about the issue?
Which MATLAB version and OS are you working upon? What was the PX4 Firmware version?

Ankur Bose

hello Leon Sievers,
On which Linux platform are you running R2020b? Please note that the UAV Toolbox Support Package for PX4 Autopilots only supports Ubuntu 18.04 in Linux

Leon Sievers

Hi,

I have a problem similar to Petar Labetic's, but on Linux and on R2020b. The installation of the support package works flawlessly, but as soon as i start the setup I get the following errors:

When I start the setup directly after the installation process:
Error using matlab.hwmgr.internal.hwsetup.launchHardwareSetupApp (line 24)

Error in matlabshared.supportpkg.internal.ssi.openHwSetupForBaseCodes

When I start the setup manually from the support package manager:

Hey,
I installed the UAV Toolbox support package and then followed the instructions to install Cygwin px4 as well as px4 source code.I validated both of them and was no problem. Then I selected 'Design Flight Controller in Simulink' then 'PX4 Host Target' with default build but when I go next and click on 'Build Firmware', it's giving me "Firmware Build Failed: No matching files were found." error.

Hi David, R,

Which MATLAB release are you using? Please use the updated SD card logging feature released in R2020b version. You can refer the following links for detailed information and example-
https://www.mathworks.com/help/supportpkg/px4/ug/sd-card-logging.html
https://www.mathworks.com/help/supportpkg/px4/ref/px4-matfile-logging-example.html

There were some issues with SD card logging prior to R2020b. Do use the 'PX4 SD Card logger' block from previous releases.

HTH,
Abhishek

Hi David
I had problems in my quadrotor control scheme because of SD card writing.
It caused the control loop to loose some cycles in random times and the vehicle lost control.
took me some time to understand its the SD...
just buy a fast SD, something in the style of "samsung extreme pro" and it will work.
Log the sensor time to the SD so you can monitor if you lost cycles in your code

David Neal

We successfully implemented a comprehensive A/P for a fixed wing RC aircraft using this toolbox. Most of the A/P flight tests were successful. The only problem we had (big one) was an occasional brownout. It happened a couple of times in flight and we almost lost the vehicle but everything came back on in time to recover. Has anyone else seen this behavior? We are using a Pixracer and the servo rail is isolated from the board power supply so I don't think it's connected to power surges. I think it might be connected to writing data to the SD card but I'm not positive.

Hi Gueon Yeon Kim,

The gps block uses the "vehicle_gps_position" uORB message to read gps data.(https://www.mathworks.com/help/supportpkg/px4/ref/read-gps-px4-example.html)
The PX4 middleware supports the gps devices highlighted in the doc(https://docs.px4.io/v1.10/en/gps_compass/.) For higher accuracy they suggest to use RTK GPS receivers, and also specify the supported devices. You can choose from the supported devices list.
Having said that, if you wish to read data from a gps device not specified in the list, then you can use the serial tx/rx blocks to decode the gps data. Some work for you as you would need to decode model and decode the gps data. (https://www.mathworks.com/help/supportpkg/px4/ref/serialreceive.html)

Hope this helps

Amit

Hi All,
Hello All,
MATLAB R2020b is live now. The R2020b version of UAV Toolbox Support Package for PX4 Autopilots provides the following new features.

-I2C support - I2C Read/Write blocks
-Support for PX4 Autopilot Firmware v1.10.2
-Simulink-Based Plant Model to Simulate Controller Model in PX4 Host Target with Lockstep Simulation
-Log PX4 Flight Data to SD Card in MATFILE format and Retrieve Data Using MATLAB Functions
-Use Connected I/O to Communicate with PX4 Host Target

gueon yeon kim

Hi, The gps block is working perfectly. However, the positioning accuracy is very low. I want to control the position with this package. What is the accuracy range of the gps block?
We are using Here+ V2 RTK. Can I only use Here+ V2 GNSS Rover module? Or is it possible to use Here+ V2 GNSS Base/Ground-station module together?

Also when I do the hardware setup, I can successfully upload the firmware. But when I click Get accelerometer data it gives me the following error message:
"The connection between the host computer and PX4 Autopilot board is successfully established. However, the serial data received is corrupted. Try again by clicking Get Accelerometer data."

Hi, I am using Simulink Coder for PX4 with Matlab 2020a and Crazyflie 2.0. For verifying that my setup works, I tried reading accelerometer data using the PX4 accelerometer block. I could build the code and it works with PX4 Host Target and jMavSim. But when I try to run it on crazyflie 2.0 I get the following error message.
"The following error occurred during deployment to your hardware board:
Invalid file identifier. Use fopen to generate a valid file identifier." Can someone please help me with it?

Alireza Ghaderi

Thanks for your response...Great... Please Keep up the work and publish I2C and other peripherals
I am still struggling to find the concepts of integrating my models inside px4 process loop...
I compiled one of the examples and then tried to connect using QGC... I faced with many errors (which is normal since firmware is not what QGC is expecting) but I cant use my peripherals anymore...for example airspeed sensor, Radio telemetry and ... are grayed out in setting... Is it OK? What happens to the default data logging on SD Card? Is it still being created ? I want to use http://logs.px4.io/ just like regular Firmware...
One more thing... Is it possible to rewrite some sensors real value displayed in QGC?
For example I create a artificial GPS Lat/Long and fed it to my control loops...but I want in QGC the real time map also shows my version of longitude and latitude?

Chunxuan Chen

Riccardo Lazzari

Is there somekind of possibility to perform HIL simulations even if it is not possible to use QGC? Im struggling in finding a simulator that con be connected to PX4 Simulink App without the use of QGC. Thanks in advance

Hi wg C

We have three examples on the PX4 Host Target ( PX4 SITL) that demonstrates how to deploy flight control algorithms designed in Simulink. The plant, and visualizations are integrated with the jMAVSim simulator. Below are the link to the examples from the PX4 doc

This tool is really excellent! I look forward to the I2C capability.

When I customize the input_rc topic and add more channels (i.e. increase from 8 channels to 10 channels), the added channels each have a fixed outputs of 874. I checked the input_source and it is PX4FMU_SBUS. I checked the channel_count and it is 16 (as expected for SBUS). Is there some reason it won't recognize the higher channels?

Kevin Schnitzler

Hi there,

Regarding to Marko's question:
Could you please further explain how it is possible to send massages from simulink to QGC Mavlink console (e.g. display my customized flight mode and some status messages).
I tried to use coder.ceval and the PX4INFO inside a matlab function, but that doesn't work out.
Or is it possible to use mavlink_log ? Like:
mavlink_log_critical(&mavlink_log_pub, "Change Flightmode to XY")

Thanks

Ankur Bose

Hello Alireza Ghaderi,
The support package are capabilities are documented here.
https://www.mathworks.com/help/supportpkg/px4/ug/px4-capabilities-integration.html
In short, the code generated from Simulink model is integrated with PX4 Firmware. The expectation is that the Simulink model would contain the Controller algorithm which would replace the default PX4 controllers. Yes you can still be connected to QGC by enabling MAVLink as documented here.
https://www.mathworks.com/help/supportpkg/px4/ug/enable-mavlink-px4.html
Till R2020a, you can connect an external sensor over serial and ADC and read the value in Simulink. I2C support will be available in future release.

Alireza Ghaderi

Hi Great Job
Is there a demo video to show the capabilities?
Its still unclear for me what is happening behind the scene when I deploy the code?
Does my simulink model override the concepts on the px4 firmware or run on parallel?
Can I still be connected with QGC?
and Is it possible to connect an external sensor (i2c or analog (ADC) or serial) and get access to that sensor in the model? then send the data to QGC? for example an external pressure sensor.. just want to see the raw value and log it...

Thanks in advance

Marko Pranjic

Hello,
Is there a way to send data over telemetry radio modules in external mode. I have read somewhere that in newer versions of Matlab, baud rate of external mode is fixed.
Is there a way to change external mode baud rate to 115200, so that I can communicate over telemetry? Do I need to change rc file?

Abhishek GS

Hello Mark,

You can use the Serial Transmit block (https://in.mathworks.com/help/supportpkg/px4/ref/serialtransmit.html) to send data to the terminal. Let me know if that doesn't solve your issue.

Nicholas Poggendorf

Hello Ankur Bose,
Thank you very much, now it works!

Ankur Bose

Hello Nicholas Poggendorf,
Yes, it is possible to use custom uORB topics with uORB blocks. After you create and place your topic in the msg folder, add the topic to the CMakelist in the msg folder and then build the firmware for your CMake configuration. Building the firmware will generate a C++ header for your custom topic and you can use the same in your uORB blocks. You have to build the Firmware every time you make any change in the custom topic.

Hello everyone,
I have a problem when using pixhawk1,2,4 with this support package that the built-in LED is always off, but the external LED linked to I2C port works well.
I have already tried to start the LED in the rc.txt with "rgbled start", which always works normally when using the support package in previous versions.
How can I solve this problem?
I'll be very grateful for your help!

Nicholas Poggendorf

Hello everyone,
Is it possible to use custom uORB topics with the uORB-blocks?
Everytime I select my custom uORB topic to subscribe to I get the following error dialogue:
Error evaluating 'MaskDialog' callback of PX4 uORB Read Block (mask) 'uORBtest/PX4 uORB Read'. Callback string is 'px4.internal.block.SubscribeBlockMask.dispatch('topicSelect', gcb);'

"test_topic" is not a valid uORB topic name.

I created the corresponding .msg file and added it to the CMake file in the /firmware/msg folder.

Did I miss something here?

Hi everyone,
For my project I need to mount 2 GPS receivers to my pixhawk and deploy my control algorithm in Simulink. I have tried that mounting the first GPS receiver to GPS port in pixhawk, and following simulink gps example works with success. However, I am not sure how to continue for the 2nd GPS receiver that I can mount to a raw serial port.
Is there any advice you can recommend? Regards!

Abhishek GS

Hi Wouter,
While running in 'Monitor & Tune', please ensure that the Simulink Stop time is 'inf'. If a finite number is mentioned, the Simulink model stops after that time expires. This is true only for 'Monitor & Tune'. In 'Build, Deploy & Start', the Simulink Stop time is not taken into consideration.

If you are still facing the issue, please reach out via technical support channel to get our attention at the earliest.

Hello everyone,
I have Windows Cygwin toolchain and when I type "make posix_sitl_default jmavsim" I obtained errors from accelerometers and gyros. Do anybody know the solution??. I'll be very grateful for your help!

Wouter Van Houdt

Hello everyone,
Update on my previous post: running jMAVSim from inside Simulink works perfectly fine when using 'Build, Deploy & Start', it's only when 'Monitor & Tune' is used that Simulink stops. We've also encountered this problem multiple times now with the example provided by MathWorks.

Wouter Van Houdt

Hello everyone,
I have a question about the PX4 Host Target and jMAVSim combination. My colleague and I are trying to use this method to test our attitude controller in jMAVSim. In our Simulink model we directly control pitch, roll, thrust and yaw with sliders (as in the 'px4demo_PositionController_quadrotor' example). When we click 'Monitor & Tune' jMAVSim starts as normal and the drone behaves according to the initial slider values. However, as soon as we change the slider values, the run time in Simulink stops and the drone doesn't react to the changes in jMAVSim. It seems as Simulink pauses/crashes while everything else keeps running. We also encountered this problem once when playing around with the 'px4demo_PositionController_quadrotor' example, but with our own model it happens everytime. Can this be a bug or are we doing something wrong?

Ankur Bose

Hi Khalil,
Can you please try out the below things?
1. Without rc.txt, check the vehicle_attitude uORB topic value in QGC to see whether you still see the huge rotation
2. With our rc.txt, without px4_simulink_app, check the vehicle_attitude uORB topic value in QGC. Here, we will know if there is any effect of removing many modules of px4.

Khalil Mokhtari

Hello everyone, I hope you are doing well
After deploying the PX4demo_attitudeSystem onto the PX4 board, when running in external mode and placing the PX4 on a perfectly level surface, the scope shows that the sensors are giving huge rotation for the pitch angle. Although the sensors are well calibrated by the QGC. I'm not sure if the vehicle attitude estimator is started correctly in the rc.txt. Has anyone ever encountered such a problem? any solution?
Thank you in advance.

Hello All,
MATLAB R2020a is live now. The R2020a version of Embedded Coder Support Package for PX4 Autopilots provides you a way to deploy the PX4 Executable on the host and connect with the jMAVSim simulator. You can also run Processor-In-Loop (PIL) simulation for your Pixhawk hardware. The support package also contains a deployment solution for Crazyflie 2.0 which is a palm-sized drone.

Ankur Bose

Hello July,
Are you still facing the issue? Can you share the full build failure log?

Mrudit
You should add to your rc.txt mavlink protocol on telem1(ttyS1 on nuttx)
add this lines:

mavlink start -d /dev/ttyS1 -m config –x # for mavlink protocol -telem1 port
mavlink boot_complete

and dont forget in the simulink app, in the hardware configuration ,in the baudrate of s1 port , to configure it to 57600
that worked for me

Mrudit Trivedi

I have been trying to run simulink files but unable to connect the Pixhawk to MATLAB over wifi using the esp8266 wifi module as it does not detect the port. I believe there is some Mavlink code missing/incorrect in the rc.txt file, as the Pixhawk connects to QGC over wifi perfectly without this file. I have tried all combinations of the code and 'serial port' options in the Configuration parameters>Hardware Implementation of Simulink, that i could find in the documentations.

Mavlink WIFI Bridge parameters:
WIFI_UDP_HPORT = 14550
WIFI_UDP_CPORT = 14555
UART_BAUDRATE = 57600

My rc.txt file has the following code:

#Copyright 2018 The MathWorks, Inc.
# This is the custom rc.txt which loads px4_simulink_app on start-up

Hi Erina Nesbit,
We are working to provide I2C support in future MATLAB release. Can you let us know what external sensors you are using?

Ankur Bose

Hi Benyamin Krisna,
Are you able to read the GPS data over the serial port? It is possible that the area you are working in is not receiving GPS values. Try connecting the GPS sensor to a raw serial port, in the Simulink model, loopback the serial data to another serial port and observe the values

Abhishek GS

Hello Erina,

We are working on supporting I2C channels through Simulink and it is planned for a future release. Could you please let us know what external sensors are you looking forward to using?

July

islam dib

Hello,
Please, where can I found the PID parameters to control the attitude and altitude ?
Is it possible to change this parameters online, e.i while rotors turn?

Erina Nesbit

Does anyone know if this package supports the i2c channels? Most of my external sensors are connected via the i2c only.

Benyamin Krisna

Hi Ankur,
yeah, I got that part figured out. Do you know the problem with the GPS? And is there another way to control the LEDs then?

Ankur Bose

Hi Benyamin Krisna,
Because both MAVLink and External mode require the same USB serial port to work, only one of them can work at a time. Enabling MAVLink on the USB serial port in rct.txt will cause External mode to not work.

Benyamin Krisna

Hi Ankur,
it seemed that the error occurred when I modified the mavlink command in the rc.txt data. After I changed it back it went to normal.
Nevertheless I still couldn't access the GPS data. I used the px4_readGPS blocks: the status seems to be 1 (on) but no GPS data were retrieved. I tried this with several GPS (I have a Pixhawk 2.1 Cube and a Pixhawk 4 with different GPS modules), but neither worked.

Ankur Bose

Hi Benyamin Krisna,
I believe that you are facing 2 separate problems.
1. External Mode fails with the "timed-out" error.
2. Unable to send data using PWM or control LEDs

Regarding 1, do you see the issue with all models or just for some particular models?
Regarding 2, you cannot control the LEDs in Pixhawk Cube 2.1 using uORB topic, but you can definitely send PWM values. Have you completed the SD card process as mentioned in the doc?

Hi Yuichi Tadokoro,
Thanks for reporting the issue. You don't need to be in the same folder as your PX4 in Simulink. It looks like an issue with being unable to change directory to the PX4 in WSL. Where is your PX4 firmware located? Also, from R2019b, we officially support the Cygwin toolchain in Windows as that is the one that is maintained by PX4 ecosystem. The support for WSL would be deprecated in a future release.

Ankur

Yuichi Tadokoro

I found that the following error occurs if the simulink model is not in the same drive as 'mypx4' folder. Hope this will be fixed in the next release.

FYI, I'm using MATLAB 2019a and PX4 Support Package v19.1.3 with WSL on Windows 10, and I have set SwitchPath to 1.

Hello again,

I solved my problems on pixhawk 2. Flashing with mission planner works but doesn't solve the port change problem on my computer. When i do in that manner, port problem doesn't affects control software and successfully connects, but because of ports, matlab upload fails.
So shortly, if you come up to advanced port settings via windows device manager, change com port and make both changable port numbers same, you can by-pass the problem. However port definitions change, numbers are same and windows be trickked. Build, upload processes could be done in Simulink PSP. However, in that approach, i fail to connect control softwares. I will also need to try Qground upload approach.

My other problems reason is incorrect sdcard settings, i fix that.

Burak Yörük

Hello everyone,
I have a problem about uploading the firmware in setting up PX4 support package. I'm beginning to tell in long way about what I did. First, I observed my port oddness which i think about that cause. In initial moment in USB connection, Device Manager shows "ProfiCNC CUBE F4 FMU(COM3)" but within 5 sec. it's changing to "Legacy FMU(COM6)".
I tested and found out Support package only can upload on ProfiCNC CUBE F4 FMU(COM3), Legacy defined COM6 useless for uploading, can't find. So I handle in a kind of way that begin uploading process within 5 sec. in connection. But after, getting Acc. Datas failed cause of that issue, uploading demo examples also stucked.
The first question is
"Attempting reboot on COM6 with baudrate=57600...
If the board does not respond, unplug and re-plug the USB connector"
I suppose the have to change baudrate(57600 to 115200) to overcome this problem. How can i change that baudrate ?

So, i tried another way, just generating code in Simulink via SP and building manually on bash. When building manually i had error message like
../../src/modules/px4_simulink_app/MW_PX4_TaskControl.h:61:1: fatal error: px4demo_LEDBuzzer_types.h: No such file or directory
#include MW_StringifyDefine(MW_StringifyDefineTypesX(MODEL))
^~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
and I found that's about MODEL.h library, I can't solve it and build on bash. That's second question.
On the other hand if i try building on Simulink, it works, no errors. I flash .px4 build file via Mission Planner. But running px4_simulink_app nothing change on HW. Considering px4_LedBuzzer demo. That's third question.

I'm very tired guys, any help pls. I just want to see any activity on my pixhawk cube.

Windows 10 version 1809
using Pixhawk2 Cube with px4 v1.8.0

After loading the Simulink model to the pixhawk using the awsome 'Embedded Coder Support Package for PX4 Autopilots', I couldn't arm the motors and start the flight, I'm sure that there is something missing in the 'rc.txt' file in the SD card, but I do not know how to fix that, looking for your help
thanks

Thanks a lot for your answer regarding PIL. Really happy

mechali omar, Petar Labetic,
Which manual 'PX4 Autopilots Support from Embedded Coder' are you referring to? We had a manual for the pilot version of the support package till R2018a and the manual is not applicable from R2018b. The pilot version of the PX4 support package has been replaced by the official version from R2018b. Please refer to the official version of the support package documentation https://in.mathworks.com/help/supportpkg/px4/index.html for any help/troubleshooting

Petar Labetic,
Can you tell us how did you install the support package? From the error log you shared, it looks like the installation of the support package is not correct.

mechali omar

Petar Labetic
have you finished installing Embedded Coder Support Package for PX4 Autopilots?
have you finished installing toolchine?

mechali omar

Balaji Kartikeyan Chandrasekaran
have you finished the set up of SD card? because the rc.txt file in the Sd card will start the Simulink model you uploaded to the pixhawk

Hi all, I am new to using pixhawk support in embedded coder. I followed everything as per setup. I tried to run the log file example and matlab loads it into px4 but px4 doesn’t do anything I.e. No log file. I tried to pair px4 with qgroundcontrol to make sure the sensors were working and it did. I even connected to px4 using MAVLink . It seems that it fails only when using simulink model. Can someone help me out or facing similar issues? I am using MATLAB 2019a

Petar Labetic

Hi Omar. Yes I have followed the manual but the error occurs in the first step when I click on the setup option in the Add-ons manager for setting up the hardware.

mechali omar

Petar Labetic, have you followed the manual 'PX4 Autopilots Support from Embedded Coder' ?
In which step are you struggling?

Petar Labetic

Hi. I keep getting an error every time I try to setup the support package. I see people have been already asking but no answer. I also ran the command system('wmic os get Caption') and got:

My friends do we need to set a target for the pixhawk to enable PIL simulation , or it's already set? of it's exists, what's the appropriate 'hw', and 'tgt' name since we need that in
pil = addNewPIL(tgt,'MyPIL');
map(tgt,hw,pil,'My Serial Interface');

and others commands

mechali omar

Guys, it is solved. the error is due to that I make several copies of the parent model in different directories. I deleted all of them, and I just set up the COM port, and it's good.

mechali omar

Hello Ankur Bose,
Thanks, the problem has been solved just today. but how, I don't know hhh
I'm using MatLab R2019b.

Another thing, I', trying to deploy the attitude control model to pixhawk but I'm getting this error "Hardware board settings must be the same for all models in the Model Reference hierarchy. To inspect these settings, open the model Configuration Parameters and select the Hardware Implementation pane"
We are kindly looking for a precise tutorial which show exactly the steps to be followed, including hardware setting.

Ankur Bose

Hi mechali omar,
What is the MATLAB version you are using?

Ankur

mechali omar

. Currently only v1.8.0 version of PX4 is supported. If the version is less than v1.8.0, the firmware
build may fail in further screens. If the version is greater than v1.8.0, the functionalities may not
work as expected. We recommend you to specify a PX4 firmware directory with version v1.8.0.

mechali omar

Hi
I got the following error Firmware validation failed: No matching files were found.
MATLAB 2019b
it 's asking me to provide a file for firmware version v1.8.0

Daniel Frank

Hi Ankur,
Thanks for the info. There is no specific reason, the project is just currently using 1.9 and we want to avoid porting everything back to 1.8, as porting the generated code to 1.9 is probably less work.

Ankur Bose

Hi Daniel Frank,
The upgrade of the firmware support to the newer PX4 firmware versions is on the roadmap. Can you let us know why you are interested in the 1.9 or 1.10 version? What trouble you are facing with v1.8.0?

Daniel Frank

Hi,
I need to use this together with PX4 firmware 1.9 or the upcoming 1.10. I was able to port the generated code to these newer versions but some things are still causing trouble.
Before spending any more time on this I would like to ask if any upgrade to a newer firmware version is planned in the near future?

Ankur Bose

Hello All,
The Embedded Coder Support Package for PX4 Autopilots is now available in R2019b. The support for Cygwin Toolchain for Windows has been added in R2019b. If you are working in R2019b in Windows, you can now use the Cygwin Toolchain to build the PX4 firmware instead of using WSL.

Problem was that I didn't perform PX4 System Startup from SD Card

Hi andyfl, Yu-Ru chien,
Please reach out to us through Technical support channel so that we can help you better.

Yu-Ru chien

Hi,Ankur Bose,
Yes, I did. But the error stil occured.
I even changed my matlab version from R2018b to R2019a,and finished the Hardware setup again.
However, it didn't work for fixing the error.
it's very weird that I am able to use COM3 aka /dev/ttyACM0 to upload firmware by Hardware Setup screen, but can not use COM3 to connect PX4 Pixhawk 1 on running External mode.
please help.

Btw, if somebody uploaded your firmware successfully, can you share me waht you have done form start to finish please ...

andyfl

Hey, I have the same issue and can't manage to get rid of it. I'm using MATLAb 2018b and Pixhawk 1. I also tried several Baudrates and the command
setenv('MW_PX4_WIN10_BUILDCMD', 'cmd /c start cmd /k "C:/Windows/Sysnative/bash.exe -cli "make $(CMAKEMAKECONFIG) " 2> MWPX4BuildLog.txt & echo MW_BUILD_COMPLETE >> MWPX4BuildLog.txt " ');
The commands you suggested
setenv('MW_PX4_WIN10_BUILDCMD','')
setpref('MW_PX4_WSLBuildPath','SwitchPath', 1)
don't work either.
My px4_read_demo file contains a 'uORB Read'-Block and several 'Display's as sinks. MAVLink's been disabled all time. I tried it on Windows 18362 and Ubuntu 18.04 with the same result.

please help

Yu-Ru chien

Hi Ankur Bose,
Beacuse I enabled MAVLink over USB port.
Should I use other port for enabling MAVlink and run External mode on USB port ?

Ankur Bose

Hi Yu-Ru chien,
Can you tell us why you are using Serial 5 on Pixhawk 1 for External mode instead of using the USB port aka /dev/ttyACM0 ?

Yu-Ru chien

I have completed the SD card setup and inserted in Pixhawk 1 flight controller.
But when I run my own firmware on external mode( /dev/ttyS5 aka Serial 5 ), a error occured on connecting the Pixhawk 1 and said the following :

p.s. I set the baudrate of Serial 5 at 57600

Hi Ankur Bose
thank you for replying to my comments.
The command setpref('MW_PX4_WSLBuildPath','SwitchPath', 1) didn't work .
and setpref('MW_PX4_WSLBuildPath','SwitchPath', 0) won't work either ,because the command i need is 'setenv('MW_PX4_WIN10_BUILDCMD', 'cmd /c start cmd /k "C:/Windows/Sysnative/bash.exe -cli "make $(CMAKEMAKECONFIG) " 2> MWPX4BuildLog.txt & echo MW_BUILD_COMPLETE >> MWPX4BuildLog.txt " ')',,not antything else.
The command 'setpref('MW_PX4_WSLBuildPath','SwitchPath', 1) ' won't help me get the correct setenv command i need.

Ankur Bose

Hi Dale,
Have you looked at the below documentation? This should solve your problem of setting the environment variable every time.
https://in.mathworks.com/help/supportpkg/px4/ug/troubleshooting-px4-build-model-windows.html

dale

I met the same two issues
1、Unable to locate build tool "GNU PX4 Archiver": echo
I found a command to settle the problem temporarily

setenv('MW_PX4_WIN10_BUILDCMD', 'cmd /c start cmd /k "C:/Windows/Sysnative/bash.exe -cli "make $(CMAKEMAKECONFIG) " 2> MWPX4BuildLog.txt & echo MW_BUILD_COMPLETE >> MWPX4BuildLog.txt " ')

you should run the command everytime before you want to build the simulink model,but,anyhow,this method solved my problem.
2.Unable to connect to the 'PX4 Pixhawk 1' target
i have not solve the problem yet.

when i was trying to solve the first problem,i found the command line in the file“C:\ProgramData\MATLAB\SupportPackages\R2018b\toolbox\target\supportpackages\px4\+codertarget\+pixhawk\+internal\setupBuildEnvironment.m”

i read the code ,and i found that there might be something wrong.

i tried every possible setenv('MW_PX4_WIN10_BUILDCMD',‘string’) command in the file to test which is the correct one,
finally i found that only the command i mentioned above is appropriate

Here comes the problem:
my windows version is 18362(i got the windows version after i ran the command “codertarget.pixhawk.internal.getWindows10Version()”),
i also checked getpref('MW_PX4_WindowsToolchain','UseCygwin') command the result is 0
so the 'setenv' command i might get at last is
"setenv('MW_PX4_WIN10_BUILDCMD', 'C:/Windows/Sysnative/bash.exe -cli "make $(CMAKEMAKECONFIG) "') ;"
or
"setenv('MW_PX4_WIN10_BUILDCMD', 'C:/Windows/System32/bash.exe -cli "make $(CMAKEMAKECONFIG) "') ;"
however ,i tried the two command above but they didn't work.

so i guess there might be something wrong in the way we set the MW_PX4_WIN10_BUILDCMD.

Ankur Bose

Hi Daniel,
The mixers are usually defined in the PX4 Firmware for each airframe. In PX4 v1.8.0, the mixers are defined at https://github.com/PX4/Firmware/tree/v1.8.0/ROMFS/px4fmu_common/mixers
The mixer defined in motor_mixer in px4demo_attitudeSystem model is actually a MATLAB function for a hexacopter. If you want to bring a mixer for your airframe in MATLAB, create a MATLAB function for your mixer as listed in the above link.

Regarding the External MOde issue can you please confirm if you have completed the SD card step as described in hardware setup screens and your Pixhawk 1 has an SD card connected inside?

Daniel

Quick question:

Can you point me in a direction to understand how the mixers are implemented in matlab? I don't seem to understand the motor mixer block.

Thanks. Sorry i'm sending many messages. Its so that when you eventually read this, you can just address all of them at once.

Thanks once again.

Daniel

Hi support team,

I have installed the suport package on Ubuntu 16.04. I was able to build the firmware successfully, and upload. However, I am unable to read accelerometer values from the Pixhawk1 (the device I am targeting).

Secondly, when I try to run the example models (i've tried about 3 now), it builds fine, but then gets to a point and says the following (copied from diagnostic window):

Build process completed successfully
host endian mode: Little
Component:Simulink | Category:Model
byte swapping required: false
Component:Simulink | Category:Model

Component:Simulink | Category:Block diagram error
Unable to connect to the 'PX4 Pixhawk 1' target for 'px4demo_Read_Parameter'.

Please help. I tried to do some googling and similar error occured for Arduino users as a result of baudrate issues in non-original boards. I tried to reduce the default baudrate on the 'target hardware resources' in the setup to 57600 which I know to work with 'screen' on DTFI cable. That didn't work. I reduced it further 38400, still didn't work. Please help.

Thank you.

Hello zjwrj,
Please execute the below two commands in your MATLAB command window to resolve the issue:
setenv('MW_PX4_WIN10_BUILDCMD','')
setpref('MW_PX4_WSLBuildPath','SwitchPath', 1)

After you have execured the above commands in R2018b command window, try building the Simulink model again.
