STM32F103 drum machine / 12bits
Output 1.3" 128x64 OLED via Arduino Nano as SPI slave. Capacitative touch for drum triggers
TODO:
- Basic operation from pre-programmed pattern
- SPI transfer to Nano and live pattern display on screen
- Play/ Pause/ Record buttons
- Digital tempo change
- Shorten samples / save length pattern
- Reduce gain / save gain pattern
- Display gain / length on screen
- Swing?
- Capacitative touch buttons >= 8
- Multiple buffers for multiple PWM output?
- Save / recall patterns
- DAC output
- MIDI input (at least for tempo?)
