// DESCRIPTION:
//
// By moving the joystick right and left, the user can set up one unit for TX (left) or RX (right).
// After setting the correct mode, the user must press the joystick button to start the link tester.
// The transmitter will send one packet every time the S1 button is pushed.
// Number of packets that have been transmitted is showed on the LCD display. The RX unit will display
// number of packets received with CRC OK.
// The program uses halRfSendPacket() and halRfReceivePacket()
