WebFeb 10, 2024 · A typical CAN frame uses a 15 bit CRC checksum. This is what the SAE_J1850 fills in on its own and you can't even modify when using that chip. It would seem that what you are dealing with is a very device specific encoding. There could be a CRC in there of course, but that is totally independent of the normal CAN CRC. WebAug 9, 2024 · 2. To implement the initial value for the CRC you just have to set crc in the beginning to what you want to have. So either. uint8_t crc [8] = {1,1,1,1, 1,1,1,1}; or. memset (crc,1,8); But you have a flaw in your logic and that is the reason why you do not get the right values (even without the init value).
