Error when using HCSR04 example
조회 수: 8 (최근 30일)
Using the HCSR04Example.m file only edited for the pins I am using on my Arduino Uno and COM3 instead of COM38 with Arduino hardware support and HC-SR04 Add-On Library for Arduino. I keep getting the error:
Updating server code on board Uno (COM3). Please wait.
Error using HCSR04Example (line 25)
The Arduino source 'Ultrasonic/Ultrasonic.h' for libraries 'JRodrigoTech/HCSR04' cannot be found. Install the 3P library source first and try again.
Have I not installed an add-on or not taken something else into account?

Even after installing the necessary libraries the error "The Arduino source 'Ultrasonic/Ultrasonic.h' for libraries 'JRodrigoTech/HCSR04' cannot be found. Install the 3P library source first and try again "still exists

First download the file from this link
there is another file in the describtion, download it and put it in the arduino file in matlab
or type arduinoio.IDERoot in command window to see the directory of the file
if you get this error:
Cannot program board Uno (COMX). Please make sure the board is supported and the port and
board type are correct.
then rename the Arduino folder in Documents into anything else. and open the arduino.exe
from this folder (C:\ProgramData\MATLAB\SupportPackages\R2016b\3P.instrset\arduinoide.instrset\arduino-1.6.13/libraries)
you'll get this message "The sketchbook folder no longer exists. Arduino will switch to the default sketchbook location , and create a new sketchbook folder if necessary. Arduino will then stop talking about himself in the third person."
also it will help if you run matlab as an administrator

Note that the HCSR04Example.m from the 'HC-SR04 Add-On Library for Arduino' requires MATLAB R2016a or higher and MATLAB Support Package for Arduino Hardware.
Make sure that the Arduino Support Package is installed correctly by running this command -
Ensure that you have followed the installation steps mentioned in this link such as renaming the unzipped folder to ‘Ultrasonic’.
Check if MATLAB is able to detect the add-on library by executing the "listArduinoLibraries" command. You may have to restart MATLAB after installing this library.

Please ensure that you have installed the 3P library of the Ultrasonic sensor from https://github.com/JRodrigoTech/Ultrasonic-HC-SR04/archive/master.zip
Refer to instruction on the doc page https://in.mathworks.com/matlabcentral/fileexchange/57898-hc-sr04-add-on-library-for-arduino to install this library.
