The resulting CRC is the CRC code register. (5) Repeat steps 2 to 4, for processing the next 8-bit data. (4) Repeat step 3 until the right eight times, so that the entire 8 bits have been processed. (3) after the least significant bit CRC register or dissimilar detection, if the lowest bit is 1: CRC register to the right one, then the polynomial A001H or different if it is 0, the CRC register right by 1 bit, with or without exclusive polynomial. The first 8-bit data and lower 16-bit CRC register or different, the results put in the CRC register (1) Preset register 16 is FFFF hex (i.e., all 1's), this register is called CRC register. CRC-16 (Modbus) CRC-16 (Sick) CRC-CCITT (XModem) CRC-CCITT (0xFFFF) CRC-CCITT (0x1D0F. 1) the CRC register initial value FFFF i.e., 16 bytes are all 1 ΔΆ) CRC-16 / MODBUS polynomial A001H (1010 0000 0000 0001B) 'H' represents hexadecimal number, 'B' represents the binary number Inspired by Lammert Bies CRC Calculation page, which Ive used many many times for my work and projects, I decided to write the same with javascript and without the 800 char limit, and here it is.
