/*
 * HidTest.c
 *
 *  Program to test the UsbHid with HidTest.java
 *  Java files in USBHID bindings page
 *
 *  This test program is allways sending a non blocking message and expecting to read a non blocking message
 *  Messages are sent with the last byte cycling through '0'-'9' and LED4 toggles with each send
 *  When a messsage is received:
 *    LED2 toggles
 *    Received message is sent, blocking.
 *    A message is read blocking
 *    The recived message is now the new non blocking message to be sent
