The idea is to use the Pandora and it's I/O on the Ext-Connector in combination with an MSP430, buttons/knobs, and Character-display, to make a 'stompbox' effects-pedal using hardware inputs and software processing.
Contents
Hardware
- Pandora portable computer
- MSP430 Launchpad for prototyping (communicating over UART)
- ext-connector and breakout-board
- Audio-plugs, buttons, knobs (pot-meter? rotary-encoder?), hd44780-display,
Software
- Puredata - (With some externals: comport, wiimote, iemmatrix, pdp?)
- Jack2 (jack1 has alignment error-thingies) - Can get as low as 21.3msec latency.
- MSP430-embedded code
- Protocol to talk between Pd and controller (read buttons, send lcd-message)
Ideas
- Use Pandora touchscreen for direct control -> Kaospad-ish effects
- Do video-processing as well (GEM, pdp) over the video-out for live visuals (GEM may not (yet) work on OpenGL ES2)
- Next project -> replace Pandora with RasPi, which to embed inside the stompbox
