通信协议： 第1字节，MSB为1，为第1字节标志，第2字节，MSB为0，为非第一字节标志，其余类推……，最后一个字节为前几个字节后7位的异或校验和。



　　测试方法：可以将串口调试助手的发送框写上 95 10 20 25，并选上16进制发送，接收框选上16进制显示，如果每发送一次就接收到95 10 20 25，说明测试成功。-Communication protocols: 1 byte, MSB is 1 mark for the first 1 byte, 2 bytes, MSB is 0, non-first byte flag, the other analogy ... ..., the last byte for the first few Festival 7-bit XOR checksum. Test Method: Serial debugging can be written on the box to send an assistant 95,102,025, and elected 16 hex send, receive, 16-band show on the marquee, if sent once per receives 95,102,025, indicating that the test is successful .
