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FrameLen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receiving this procedure **** now sharing some of the outdated code

Code snippet for printing debug information via RS232 on atmel AVR microcontrollers (ATmega48/88/168/238 or arduino). This code uses a buffer and is interrupt driven, so printing consumes very few cpu cycles
