I'm working on a project that requires CRC calculation on an incomming packet, I have read up on CRC and I know a little about how to do it but I was told to use 8-bit CRC, my question is does the CRC get larger as the number of bytes being tested gets larger?. This allows you to optimise speed and size for your own application by selecting and benchmarking different combinations. // The last byte (7) is the rom code CRC value. Integrated and compiled without effort in both cases. You are likely wondering what are uint8_t, uint16_t, uint32_t and uint64_t.
