有没有想过在Proteus里面通过虚拟串口将2262编码发送出去，从而方便调试，这个仿真程序可以提供您尝试。注意，一定要用虚拟串口软件虚拟出两个成对的串口。另外要注意2262的时序要求。-Have you ever thought in Proteus inside the serial port code 2262 sent by virtual, so as to facilitate debugging, the simulation program can provide you try. Note, be sure to use a virtual serial port software virtual two pairs of serial ports. Also pay attention to the timing requirements 2262.
