DIGEON Synthesizer
DIGEON (DIGital AccordiON?) attempts to be a mobile synth platform using the bluepill board (STM32F103C 20KB RAM 64/128KB Flash), some buttons (initially a 4x4 button matrix), an SSD1306 0.96 screen and some rotary encoders. Sound generation will be performed using the MOZZI library.
Initially sound is output using PB8 pin. For pins used, please take a look at the source code. Most stuff can be found by looking at digeonsynth.ino file.
