"WebThe CRC field contains a 16-bit value implemented as two 8-bit bytes. The CRC field is appended to the message as the last field in the message. When this is done, the low-order byte of the field is appended first, followed by the high-order byte. The CRC high-order byte is the last byte to be sent in the message. " - Crc process_bytes

Webspecified CRC algorithm. Eight clocks are required to compute the CRC for each byte of input data. Reading the CRC computed result is a two-step process. First, the Shift register is read. This causes the result data to be latched into the Seed register. Then, the result is read directly from the Seed register. Note that the initial seed value ... WebMay 2, 2024 · A CRC is designed to detect a small set of bit errors due to line noise. Every transmission line (ie: serial cable, RF link, etc.) suffers form the effects of noise. It's impossible to eliminate it. Instead, a designer is interested in knowing how often this noise will affect data bits being sent over the line.

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.
