MSP传输数据格式问题

只看该作者 · 2015-3-11 10:19

我用MSP430F5529做一个数据格式信息的判断，想得到的结果是；
07 05 FF 00 FF
06 05 01 6B FF 06 05 31 1E FF
06 05 01 68 FF 06 05 31 1C FF

07 05 FF 01 FF
其中 07表示控制信息标志位，05 表示数据包的长度；06表示数据信息标志位；ff 00 表示开始接收数据标志位；ff 01 表示数据接收完成后发送的标志位；5d 0d 和64 36 为接收到的数据；
实际的到的结果是：
07 05 FF 00 FF 06 05 01 6B FF 06 05 31 1E FF
07 05 FF 00 FF 06 05 01 68 FF 06 05 31 1C FF
07 05 FF 00 FF 06 05 01 6A FF 06 05 31 1B FF
07 05 FF 00 FF 06 05 01 69 FF 06 05 31 1D FF
07 05 FF 00 FF 06 05 01 68 FF 06 05 31 1C FF
07 05 FF 00 FF 06 05 01 6A FF 06 05 31 1B FF
07 05 FF 00 FF 06 05 01 68 FF 06 05 31 1C FF
07 05 FF 00 FF 06 05 01 65 FF 06 05 31 1D FF
07 05 FF 00 FF 06 05 01 6B FF 06 05 31 26 FF
07 05 FF 00 FF 06 05 01 66 FF 06 05 31 1C FF
07 05 FF 00 FF 06 05 01 69 FF 06 05 31 19 FF
07 05 FF 00 FF 06 05 01 6A FF 06 05 31 19 FF
07 05 FF 00 FF 06 05 01 69 FF 06 05 31 1B FF
07 05 FF 00 FF 06 05 01 68 FF 06 05 31 1F FF
07 05 FF 00 FF 06 05 01 69 FF 06 05 31 1A FF
07 05 FF 00 FF 06 05 01 69 FF 06 05 31 19 FF
