应用VC++6.0开发的，利用max7221与计算机并口驱动8位数码管的程序。-VC 6.0 application development, the use of parallel computer max7221 with eight digital drive control procedures.

此代码主要用于并口仿真IIC口用，代码在VC++6。0下调试通过，希望对朋友们想通过并口实现IIC协议有些帮助-this code mainly for parallel simulation IIC mouth, code in VC 6. Under Debugging 0, friends hope to achieve through parallel agreements IIC some help

windows 98/95下并口输出信号方法，程序中演示了VC++6.0如何结合汇编编程的方法。
