New to BBB board, but not to Linux OS, ardupilot/rover software and mission planner.
I’m at wits end trying to get PPM input to work with BBB & Ardurover. Tried DSM port and EM pin 4 for input from an OPEN LRS 433Mhz receiver. Receiver is outputting 3.3v PPM. Receiver works perfectly with an old APM and Pixhawk controllers.
Kernel 5.10.168 - U-Boot: v2022.04
MIssion Planner - 1.3.80
What am I overlooking? I’m sure it’s something simple. (I hope)
are you using bbb or bblue ?
All interfaces with RC (Input and output) is managed by a prus code, and is most probable that you are having problem with the pru.
Are the motors/esc beeping when you start ardupilot ?
Duh… forgot there is a Black board. I’m using a blue.
ESCs are not connected yet, was doing baby steps. I first was getting anUBlox C94-M8P RTK board working via USB. Next was to get the radio working. I figured it might be an issue with PRU, but have no idea where to even begin with that.
Is there documentation that I missed on the website?
For the PRU itself no.
have had checked this one : GitHub - imfatant/test
Some information, what is the kernel version are you using ?
How is your uEnv file ?
Could you run the /opt/scripts/tools/version.sh and send the result ?
Thank you for the link. I noticed that the instructions I had followed were nothing like the steps outlined in your link. I started from scratch and followed step by step.
I now have PPM signals being displayed in Mission Planner and GPS data from ttyACM0 port. Next step is to test servo output.
My plan is to use the board to control a zero turn mower.
Again, thank you!
if there is any problem, please contact me
One thing I recommend btw, is disable INS_FAST_SAMPLE - this sometimes causes errors - IMU RESET.
