The preset 16 bit register is hexadecimal FFFF, is called CRC register;2. The first 8 bit data is different from the lower part of the CRC register or put the result in the CRC register;3. Move the contents of the register to the right one bit (towards the low), fill the highest bit with 0, and check the lowest bit;4. If the lowest position is 0: repeat step 3 (shift again) If the lowest position is 1: the CRC register is XOR with polynomial A001 (1010 0000 0000 0001);5. Repeat steps 3 and 4 until you move to the right 8 times, so that the entire 8 bit data has been processed;6. Repeat Step 2 to Step 5 to process the next 8 bit data.7. The resulting CRC register is the CRC code (the resulting CRC code is low before high after).Installation Site Requirements:1. Good air circulation around2.
