ctrl+alt is a modular firmware and hardware platform for a STM8 microcontroller, focused on real-time audio, CV, and lo-fi digital signal processing.
- logic inputs (threshold ~ 2.5V, 12V tolerable) + indicator LEDs
- 3 CV inputs (0V to 5V, 12V tolerable)
- 3 knobs up to 3 CV outputs (0V to 5V) or up to 3 logic outputs (0V or 5V) + indicator LEDs -> per output switchable via software
- 1 toggle switch
- 1 momentary button switch
I created a small software framework that facilitates the programming of the MCU. Check it out here!
