The device I/O example program uses the LED on the Development board to display a running application program on the EZ-USB chip. The buttons on the development board may be pressed to count up (F3), count down (F2), and reset the seven segment LED to 0 (F1) or F (F4). The code is written in C and uses several EZ-USB library functions. It does not use the FrameWorks. The dev_io.hex file loads into internal memory.
