TP801单板机单片教学卡

The Single-Chip Teaching Card of TP801Single-Board Microcomputer

为了适应单片机教学和应用的需要，充分利用原有的ＴＰ８０１单板机资源，设计一块ＭＣＳ－５１单片教学卡与ＴＰ８０１原ＣＰＵ插座相连，从而构成一个教学上实用的单片机开发系统。单片机教学卡硬件电路包括主电路、通讯电路、掉电保护电路、Ｐ１口状态显示电路等。与之相应的监控程序由初始化程序、键盘输入及处理程序、各个功能键的处理程序和公用子程序组成。

n order to meet the needs of single-chip microcomputer teaching and application and to make full use of original TP801 Single-Board microcomputer resources,a MCS-51 single-chip teaching card is designed,which is connected to TP801 original CPU socket to constitute a practical single-chip microcomputer developmental system in teaching. This development card includes chief circuit,communication cercuit,protection circuit of breaking electricity and state displaycircuit of P1 interface. The corresponding monitering program consists of original program,keyboard input handler,functionkey handler and public subroutine and so on.
