int main

(

void

)

Main function.

Main function.

This function initializes the MAC, initiates a MLME reset request (wpan_mlme_reset_req()), and implements a the main loop.

Main function.

The master example begins by initializing required board resources. The system clock, basic GPIO pin mapping, and interrupt vectors are established.

A memory location on a TWI slave is written with a fixed test pattern which is then read back into a separate buffer. As a basic sanity check, the original write-buffer values are compared with values read from the slave to a separate buffer. An LED on the development board is illuminated when there is a match between the written and read data.

Returns

Nothing.
