WebApr 10, 2024 · The CRC is generated from the preceding 0 to 4,000 bytes of packet data. For 1200 bps messages the data payload can exceed 4,000 bytes and when this occurs the first CRC will be inserted into the data payload and a second CRC will be started. This CRC will start with data byte number 4,001 and will continue up to 8,000 bytes. The WebC++ (Cpp) crc_32_type::process_bytes Examples. C++ (Cpp) crc_32_type::process_bytes - 7 examples found.
