44B0的串口接收发送程序 **** 现在共享这样的代码有些过时了,但这是我参考很多例子才编写出来的。集合了很多优点:采用环形缓冲机制;读数据时不必关接收中断(没有几个人能实现的),所以不会存在数据丢失的可能;以数据帧为单位接收发送;能够缓冲几千个数据帧(由fr a meLen定义)。注:本来是为Modbus协议而编写的,后来简化了校验和Modbus规范。-44B0 receiving this procedure **** now sharing some of the outdated code, But this is only reference to many examples of the preparation. Set a lot of advantages : Ring buffer mechanism; Reading of data without interruption to receive clearance (Few people realize), so there is no loss of data possible; Data fr a mes sent to the receiving unit; to the thousands of buffer data fr a me (from fr a meLen definition). Note : Originally, it was to Modbus prepared, but later simplified calibration and Modbus norms.
