  • Author: Michael Bikovitsky
  • Description: 5-bit Galois LFSR with configurable taps and initial state. Outputs a value every second.
  • GitHub repository
  • Clock: 625 Hz

How it works


How to test

  1. Set the desired taps using the switches
  2. Assert the reset_taps pin
  3. Deassert reset_taps
  4. Set the desired initial state
  5. Assert reset_lfsr
  6. Deassert reset_lfsr
  7. Look at it go!
    • Values between 0x00-0x0F are output as hex digits.
    • Values between 0x10-0x1F are output as hex digits with a dot.
  8. Did you know there is a secret CPU inside?
