UAV toolbox support package for PX4 : can I use CAN protocol GPS with custom flight algorithm?
조회 수: 4(최근 30일)
I am trying to use CAN protocol GPS module(here+ or here3 gps module) with uploading my custom flight control algorithm.
I select custom flight controller algorithm, and therefore mc_att_control and mc_pos_control module is disabled while all other modules(navigator or commander, etc) are still alive.
I uploaded my custom flight algorithm and connected CAN GPS module but seems Pixhawk4 board cannot recognize the CAN GPS.
I changed parameter UAVCAN_ENABLE to 1 to enable uavcan protocol, but this is not worked.
When I upload the original PX4 firmware, CAN GPS automatically is detected and can be used.
So I suspect uploading custom algorithm somehow affects the communication between CAN GPS and Pixhawk4 board.
Is there any method to use CAN GPS with uploading my custom flight algorithm?
Or, is it possible that uploading my custom flight algorithm affects the connection between peripheral hardware and Pixhawk board?
Thank you for Reading

I agree with your observations, The warning with GNSS is the right place to investigate further. Why is the different behaviour with original PX4 and custom controller in PX4 is surprising. One small catch I can think of is the PX4 Firmware versions. PX4 Support package is based on v1.10.2 and I am not sure what firmware version you may be downloading from QGroundControl. My guess is that this may be a latest version and that may be the reason for difference in behaviour. You can verify the firmware version with 'ver git' command in NSH console.
