Capacitive Sensing Keyboard Firmware

Rudimentary firmware for capacitive sensing. Work in progress. See the deskthority thread for how the keyboard is coming along.

What is done

• Sensing key state
• Keymap storage in EEPROM
• Basic layer system (partial)
• USB functions
  • USB HID Keyboard functions
  • Some mouse controls
• Calibration
  • Noise floor measurement
  • Basic calibration routine

Still to do

• Complete layer system
• USB functions
  • The rest of the mouse controls
  • Analog controller? (like joystick)
• Calibration
  • Set hysteresis window accordingly
  • Adjustable activation point
• On the fly macro recording
• Implement master/slave mode and communication
• Refactor main loop, learn how to use interrupts
• Tidy it all up
• Nice setup method
