TMS320F28379D: 关于bissc数据校验的疑问

收到回复：

Are you encountering an issue with the CRC calculation?

CRC calculations can be performed a number of different ways (polynomial, lookup table, etc) .  I don't recall the exact details of the last XOR performed in this particular implementation. 

There is, however, an application note on the CRC algorithm on the BiSS-C Interface webpage (https://biss-interface.com/c/downloads/biss-application-notes/) that may help resolve your question.  Refer to BiSS AN 3 and BiSS AN 21.  Note the CRC value is transmitted inverted by the primary controller so this is probably why.

也就是说，可能的原因就是因为CRC值由主控制器反向传输得到的。
