//-------------------------------------------------------------------------------------------------------
// DESCRIPTION:
//      This program allows the user to set up a simple link between two SmartRf04EBs with CC2500EM 
//      modules connected. The joystick is used to navigate through a menu, setting different parameters. 
//
//      Parameters          | Values 
//      ------------------------------------------------------
//      Packet Length       | 10 , 30, 50, 70, ...., 230, 250
//      Number of Packets   | 100, 200, 300, ......, 900, 1000
//      FEC                 | Enabled, Disabled
//      Whitening           | Enabled, Disabled
//      Radio Mode          | Rx, Tx
//
//      RX UNIT: 
//                  * Enable/disable FEC and/or Whitening
//                  * Set radio mode to RX. 
//                  * Move joystick down until the message 
//                    "Press S1 to start" is showed on the LCD display  
//                  * Press S1
//                  
//                  The LCd display will show number of packets received with CRC OK
//
//      TX UNIT:
//                  * Set packet length and number of packets to transmit
//                  * Enable/disable FEC and/or Whitening (set to the same as on the RX unit)
//                  * Set radio mode to TX
//                  * Press S1 to Start
//
//                  The LCD will show number of packets transmitted
//
//                  After all the packets have been transmitted, S1 can be pressed again to transmit 
//                  or the joystick can be used to change packet length and number of packets 
//                  to transmit
