Initialize a 16 bit register to hex , referred to as the CRC register. 2. XOR the first 8 bits of data with the low byte of the CRC register and store the result in CRC. 3. Right shift the contents of the register by one bit, filling the highest bit with 0, and check the lowest bit. 4. If the lowest bit is 0: Repeat step 3 (shift again). If the lowest bit is 1: XOR the CRC register with the polynomial A001 (1010 0000 0000 0001). 5. Repeat steps 3 and 4 for a total of 8 shifts, processing the entire 8 bit data. 6. Repeat steps 2 to 5 for the next 8 bit data. The final CRC register obtained is the CRC code (low byte first, high byte last). Troubleshooting: The displayed value on the instrument is incorrect during output. This may be due to wiring issues or communicating port failure. Please check the wiring for correctness and stability, make sure the serial port is not being used by other devices, and verify the serial port settings are correct. packing
