Drum Machine

View on project on GitHub: Firmware | PCB Shield

A sampling drum machine (inspired by the elektron digitakt) using an STM32F7

A project that is slowly moving / on hold. The majority of the required drivers have been completed, but the actual interface and audio processing requires more work

Currently implemented features

• Controls are implemented: buttons, analog pots, encoders
• Audio output: buffer, CODEC driver
• WS2812B LED feedback used for the sequencer
• Display driver: ILI9341 driver using DMA to continously stream buffer
• FATFS and SD card driver to manage audio files
• 8 channel sequencer, with 16 steps per channel
• Interface to select a sample for each channel
• Algorithm to draw a representation of the sample on the display

When time allows the next step is to plan out how the UI should work; the hardware functionality is all there but there is no way for a user to use the features in any advanced way
