// *********************************************************************
// Example for development kit DDC-RE-01.
//
// Intended for:
//   HW: - TR-72G + DK-EVAL-04x development kit with DDC-RE-01 connected
//
//   OS: - v4.06G
//      
// Description:
//   This example receives RF packets and controls relays. 
//   Packets can be sent from IQRF IDE Terminal using e.g. E03-TR.c
//   example. This example can also cooperate with DDC-IO-01.c example.
//
//   RF packet  Function
//   "S1"       switch RE1 on
//   "S2"       switch RE1 off
//   "S3"       switch RE2 on
//   "S4"       switch RE2 off
