2018: The ATMega1284P Guitar and Music Effects Pedal: Port of the Arduino Uno ATMega328 Pedalshield ( developed by Electrosmash and Open Music Labs) to the ATMega1284P which has 8 times more RAM than the Uno (16kB versus 2kB). An additional unexpected benefit is that the Mega1284 build has much lower noise component - to the extent that when I c…

2018: ATMega1284 Quad Opamp Effects Box: The Stomp Shield for Arduino from Open Music Labs use an Arduino Uno and four opamps as a guitar effects box. Similar to the other ATMega1284 repository that shows how to port the Electrsmash Uno Pedalshield, I have also ported the Open Music Labs Guitar Effects box to the ATMega1284P which has 8 times mo…
