9. Main
The main module main.c should include the main () function that is called upon startup. The main function should
first call several initialization routines and then the main program loop itself. Many of the initialization and internal
functions may be specific to the MCU hardware.
In this example the main loop sets the RF device into a continuous receive mode and wait for any incoming
packet(s). In addition, it also polls for a push button event by user. If a button is pressed, then it'll sends a payload
out using the internal FIFO and packet handler features of the EZRadioPRO device before returning to a
continuous receive mode.
