12位AD-MAX1241与SPI串口-MAX7219联合仿真 proteus版本：7.2 sp0 如果打不开DSN文件可以找升级包升到这个版本，或者按我下面贴的电路自己连好，max1241,max7219 Proteus 7.0以上版本的库里应该有的！本程序是网上找的，感谢那位网友，我将它共享了，希望大家下载学习；-12-bit AD-MAX1241-MAX7219 and the SPI serial version of the Joint Simulation pro

虚拟串口；很好用的单片机串口程序调试工具；常用于Proteus 的仿真调试。-Virtual Serial Port well with the microcontroller serial port debugging tools commonly used in the Proteus simulation debug.

AT89S52单片机之间的互相串行通信程序，可在proteus环境下仿真-AT89S52 microcontroller serial communication program between each other, under the simulation environment in proteus

基于51单片机的多路数据采集设计，调试成功，含有proteus仿真图。-Based on 51 single-chip multi-channel data acquisition design, debugging success, with proteus simulation map.
