自制51仿真器

今天下午事情比较少,拿出以前买到的sst 89c58,用万用板做了一个51仿真器,调试的时候因为手头上的编程器对这颗芯片的支持上有点问题(我觉得是bug),走了点弯路,还好顺利搞定~~


晚上整理下,上pp~

    刚刚看到此电路,对于用MAX232做为USB转RS232接口电路的可行性做出怀疑?所以决定用你这个资料做一个仿真器试一试效果后会再来发表评论

    usb? 嘿嘿 你误会了 那个我只是用的usb的插头和插座 其实还是串口

    你好,刚刚看到你的文章。

    有一个问题,请问,PCRXD与 PCTXD这两根线与串口相对应的针脚是那两个 ?

    谢谢!!!
