void platform_private_idle_task_main(void *param);

platform_private_idle_task_main is the prototype for the microcontroller Platform Library to implement. Typically, the main function will be an infinite loop that puts the processor into low-power mode waiting for an interrupt. However, you can customize this, for instance, to illuminate an LED to show when the processor is active.

The standard implementation of this for the platforms that we distribute is to place the processor into low-power mode awaiting and interrupt.
