I have one question about ADAS1000.
Does CRC calculation include Header or exclude Header?
My understanding, CRC calculation range from header to GPIO.
Is it correct?
When I select 2kHz or 16kHz date rates, bit width is 32bit.
Upper 8bit is address and lower 24bit is data.
Does CRC calculation include address and data or only data?
Yes, the CRC is computed over the entire frame.
I have another question.
When data rate is 2kHz or 16kHz, data word is 32bit(addr bit + data bit).
Does CRC calculation include addr bit?
The header is included. I have attached an example that may assist you in following how it works.
Thank you for your quick response.
And I read the attached file, however I have not understood yet.
Dear Sir Padraic,
Do you think I need to make a CRC file to get 2kHz or 16kHz date rate by SCI of YRDKRX63N ?
How to make it on code using polynomial ?
The CRC file is not needed as CRC can be disabled or ignored. For questions on the YRDKRX63N please contact Renesas.
