Overview
A capacitive touch sensing USB device.
A 32-bit version/descendant of the Cocomake7.
A work in progress prototype to learn more about ARM dev, STM32 peripherals and compare results with the AVR and teensy based versions.
The goal is to make a versatile, affordable and creative plaything, that can be used for electronics and interaction/game design workshops.

- I2C / SWD connector
Software
USB HID Device
Status: Mouse, Keyboard, Gamepad HID devices are working.
USB Serial (CDC)
symbols can be sent
USB MIDI
Note working (yet). USB MIDI devices are more complicated to implement (USB Audio Device Class, MIDIstreaming), whereas HID devices are almost trivial to implement and modify.
