33 5-bit Galois LFSR

33 : 5-bit Galois LFSR

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?
