STC单片机多机连级串口程序可实现.416路控制. 串口和485都可以使用、 一个程序可以用在26块控制板上，通过拔码开关给板子编号，每块板可以过滤分析所接收到不同的代码。进行继电器的动作，能返回数据，因使用定时器发送返回，不会阻塞或者代码错乱、可以 用在中控，物联网，等各种控制场合。修改代码后，能达到上千路的控制。
STC single-chip microcomputer multi-level serial port program can realize 416 channel control. Serial port and 485 can be used. One program can be used on 26 control boards. Each board can filter and analyze different codes received by numbering the boards with the pull-out switch. Relay operation can return data, because the timer is used to send the return, it will not block or code confusion, and can be used in central control, Internet of things, and other control occasions. After modifying the code, it can achieve thousands of control. (2020-03-06, C51, 2KB, 下载5次)
