int main ( void   ) 

Main function for the AVR414 firmware.

On reset this function will be called and it will setup the AVR for the purposes of this application. This is done by calling the local (static) applicationInit( ) member. This function will initialize the IEEE 802.15.4 stack and the serial interface. Then an endless loop is entered:

  1. call the wpan_task() function until it returns false (No more events in the queue).
  2. if new data is available:
    • call handleNewCommand() to parse it.
    • reset receiver module of serial interface. The receiver is turned off to ensure that interrupts are not nested.
