808/909 style step sequencer drum machine running on the ARM A9 HPS part of a Altera DE1-SoC dev board. Loads wav files from the SD card and uses the onboard switches to sequence a basic 8-step pattern, which plays out of onboard the line out jack.
Features:
- 8-step patterns
- BPM on 7 segment display, adjustable
- Waveform plot on LT24 LCD (very basic)
TODO:
- Swing
- More UI stuff
- Saving/recall patterns
- Get audio to work on interrupts/implement patterns task scheduler
