串口缓冲区编程
- 波特率可变；中断方式接收、发送；收发独立8字节缓冲区；可选择是否在满缓冲区后丢弃数据-variable baud rate; Disruption to receive, send; TX independent 8-bit byte buffer; the choice of whether the buffer zone after the age of discarded data
cleanbuff
- 清除串口冗余。当下位机偶然有乱码出现时，在新的通讯开始先清除缓冲区冗余信号，然后开始通讯，可以保证通讯更稳健-Clear serial redundancy. Current-bit machines have occasionally garbled when, in the new communications start to clear the buffer zone redundant signal, and then began to communications, to ensur
