   To be able to include the source files I just added:
   ```cmake
       INCLUDE_DIRECTORIES
       ${NUTTX_DIR}/arch/arm/src/stm32h7/)
   ```
   to the CMakeLists of my app.
   
   Using gpio interrupt I seem to be limited by the resolution of the system 
clock when using `clock_gettime(CLOCK_MONOTONIC, &now)`, which caps me at 
100Hz. How can I fix that? Increasing system clock? Going tickless? Using 
another timer?
