Wiegand Protocol Flow Chart
Example:
Here we take the license plate number HK55EVB as example.
The coding steps are shown as follows.
Steps:
1.
Convert HK55EVB by SHA1 mode is: 0x80cf15.
2.
Output a 8-bit binary code for each set of number via the Wiegand interface:
1000
0000 1100
1111 0001 0101
3.
Bit 1 is an even parity bit for the first 12 bits (bit 2 to bit 13), as 1.
4.
Bit 26 is an odd parity bit for the last 12 bits (bit 14 to bit 25), as 0.
Results:
You can get a binary code as
1
1000 0000 1100 1111 0001 0101
0
.
