A modular firmware and hardware platform for a STM8 microcontroller, focused on CV and lo-fi digital signal processing.

CTRL+ALT Front Panel
  • 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!
