Sorry if this is a dumb question, I am new to PX4 and cmake.
I am trying to add a driver for a propeller rpm sensor: I have modeled the code and makefile off another driver and placed them in src/drivers/rpm, but it seems like they are not being “seen” by the compiler. In the build folder, there is no build/src/drivers/rpm folder like there is for all the other drivers and the main function does not show up in build/src/firmware/nuttx/builtin_commands.c.
What am I missing? Thanks in advance.
@annavt:
Please paste the contents of your CMake file here.
Also, have you added your rpm module to the CMake compilation file for your board. I.e. have you added drivers/rpm to your nuttx_px4fmu-v2_default.cmake file? (Note you will have to change the correct board CMake file for the flight controller that you are using).
Adding it to nuttx_px4fmu-v2_default.cmake did the trick. Thanks so much!
What sensor you were using to measure the rpm ? If you don’t mind can you share the rpm driver code you have written for the sensor.
