C语言实现W78E365普通IO口的UART传输

Realization of UART Transmission though Common I/O of W78E365 Based on C51

在SMT贴装线的某外围设备中,原使用一个增强型全双工串行口的W78E365单片机进行驱动。由于设备功能拓展,需要用到多个使用UART协议的串行口进行数据通信。针对这个问题,利用KeilC51来进行软件开发,"以软代硬",实现W78E365单片机的多串口扩展,保证了功能拓展后的设备稳定运行。此方法有助于解决硬件资源不足时遇到的问题。

W78E365, used in a SMT peripheral, has only one enhanced full -duplex serial port. As expansion of the machine, it needs to use multiple UART transmission. Here, take advantage of the idea of software instead of hardware and realize the multi - UART expansion in Keil C51 to ensure stable operation of the equipment for the new requirement. This method can cover the shortage hardware resources.
