ADS127L01 - efficient CRC-4-ITU implementation?

Other Parts Discussed in Thread: ADS127L01

Hello,

I am using the ADS127L01 in frame sync master mode, where each reading from the ADC has a 4-bit CRC using the CRC-4-ITU algorithm. Does anyone have a table driven (or similarly efficient) software implementation of calculating this CRC? I have a "simple" bit by bit implementation, but it is quite slow. 

Thanks.

    Hello Andrew,

    I'm sorry that no one has replied with such a table implementation of our CRC calculation. Our group does not have one made that we can provide.

    I will continue to leave this thread open in case anyone else eventually replies.

    Regards,
