How to add driver to custom project?

[rlimberger]

Thank you for sharing this driver and sorry for abusing the issue system for a question .

Could you describe what one needs to do to add this driver to a custom application? What i did is the following:

• copy the following directories to my workspace (the folder above my application folder): drivers, nrf_servo, include
• add the boards folder to my own application folder (next to my src)
• add CONFIG_NRF_SERVO=y to my proj.conf
• add #include "drivers/nrf_servo.h>" to mu main.c

However, when i build my project i get:

workspace/blinky_3/prj.conf:2: warning: attempt to assign the value 'y' to the undefined symbol NRF_SERVO

I assume that the driver (added to my workspace) is not seen by cmake? However, i cannot see how that is configured from your example project. Could you elaborate how you got the custom driver to be recognized?

I should say that i am new to zephyr and nRF Connect so i might be missing something obvious.

Thanks!
