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 compare the Uno and the Mega1284 using the same support circuitry it is not unreasonable to describe the Uno as "noisy" and the Mega1284 as "quiet". The larger RAM means that a much longer delay effect can be obtained - and that is demonstrated by the Arduino sketch example that I have included.

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 more RAM than the Uno (16kB versus 2kB).

This library enables you to use Interrupt from Hardware Timers on an AVR ATmega164, ATmega324, ATmega644, ATmega1284 with MCUdude MightyCore. It now supports 16 ISR-based timers, while consuming only 1 Hardware Timer. Timers interval is very long (ulong millisecs). The most important feature is they are ISR-based timers. Therefore, their executions are not blocked by bad-behaving functions or tasks. This important feature is absolutely necessary for mission-critical tasks
