ECM-408 (Electronic Control Module 40 buttons 8 pots)

Arduino based analog and digital controller for what ever you want to do, HID, MIDI, etc…

WIP

Features

• 40 digital inputs (24 mm OBSC-24 arcade buttons)
• 8 analog inputs (6mm shaft 10K POTs)

Parts

• Push buttons (x 40)
• 10K POTs (x 8)
• Wire
• Microcontroller board with at least 1 analog port and 5 digital ports.
• 8x8 74xx4051 mux (x 1 if using a small board) (https://github.com/ellisgl/analog-multiplexer-8x8)

Directories

base_sb_mux: Base code that works with the smaller Arduino boards (Uno and such). Uses an 8x8 multiplexer.

base_lb: Base code that works with the larger Arduino boards (Mega and such). No mux needed.

midi_serial_sb_mux: Serial MIDI controller version of base_sb_mux.

midi_serial_lb: Serial MIDI controller version of base_lb.

TODO

• Schematics for the two main types.
• Update diagrams for default button map.
• Add a Row / Column mapping image.
• Create HID versions.
• Create a hardware debounced versions - will involve a separate CPLD project done in Verilog (https://github.com/ellisgl/addressable-debouncer-verilog).
• Maybe move the mapping into their own file?
