- GitHub repository
- Clock: 0 Hz
How it works
Calculates a running error correcting code. For each new byte applied to the input pins, calculates a running longitudinal redundancy code.
How to test
Supply a byte to ui_in, read the LRC on uo_out. Keep feeding it bytes and you'll keep getting new LRC codes. Code resets when the chip resets.
External hardware
No external hardware needed.
