Configuring the Firmware

The default application performs as described in the Overview. There are numerous compile time options that can be added to change the example design without requiring code changes. To change the options explained in the table below, add the desired configuration variables to the APP_COMPILE_DEFINITIONS CMake variable located in the example’s CMake file here.

If options are changed, the application firmware must be rebuilt.
