基于CYPRESS CY7C68013 usb2.0的开发程序，该程序演示了访问IO的编写方法。-This directory contains the dev_io 8051 firmware



The purpose of this software is to demonstrate how

to use the buttons and LED on the EZ-USB developer s

kit.



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.
