Schematic for the controls

[tomcartwrightuk]

The Readme specifies how to connect up the screen but not the controls - is there a layout on the interwebs somewhere that could be linked to? Thanks

Hi @tomcartwrightuk, sorry for late response. Short answer: unfortunately not.

I'll look for the schematic (but I doubt if I still have it) and will post it, but I wouldn't hold my breath.. Honestly shouldn't be that hard, there are only few elements, I'm using SN74151 as multiplexer for buttons, so inputs from buttons go into that, and then this element is wired to the GPIO ports (which: https://github.com/szymonkaliski/LoopPI/blob/master/Controller/app.js#L20-L25), the potentiometers are wired to MCP3008 which works as ADC and multiplexer, and is wired to the GPIO ports (which: https://github.com/szymonkaliski/LoopPI/blob/master/Controller/app.js#L12-L17).

Hope this helps at least a little?
