  Ah, when I run the PWM program there is no chatter on the PWM signals, so I'm going to review that code again and compare it to mine.

  I know this is kinda an old post but I have created a driver for px4 that can use both flavors of the MS5837 the bar2 and bar30. I will create a pull request with px4 so it will be available.

  Well, we aren't routing the 5V on that little M0022 board to prevent it being used to drive servos (for this concern). But 5V does come down to the connector, so it could be soldered to, and you could create solder bridges on the bottom of the board. Not ideal, but 5V is there, just not routed....

  Hey @Andrew-Keefe , This isn't something I've tried. Curious as to what the setup looks like if you're up to share more details. Thanks, Travis

  Hi @Andrew-Keefe, I'm not positive on this one. I have an example of using UART for an ESC here, and I remember having to be careful what task was opening the UART port: https://github.com/modalai/px4-firmware/blob/modalai-1.11/src/drivers/uart_esc/modalai_esc/modalai_esc.cpp#L736 Here's opening of the port (note: this is beta level code) https://github.com/modalai/px4-firmware/blob/modalai-1.11/src/drivers/uart_esc/modalai_esc/modalai_esc_serial.cpp#L48

  Thank you @modaltb. I was able to control the LED with my code (yellow = waiting for serial, blue = data valid, red = data not valid).

  Thanks @modaltb , that worked! I had to set it to run as a background function using the &. It's running perfectly now. I probably want to rewrite it as a task, but that example code looked tough to follow. I wish the PX4 developer manual included more step by step tutorials, like the ROS tutorials.

  Hi Andrew, We have other folks using it for controlling ESCs, let me try to see what I can find as far as examples, we don't have one in our repos. PX4 itself has a UAVCAN implementation they've been working on that might be of help: https://dev.px4.io/master/en/uavcan/index.html Thanks! Travis
