Tessel Key aims to be a fully configurable NKRO keyboard software for the Tessel microcontroller.

• Present Tessel as a keyboard to a USB host
  • Ideally, (optionally) present itself as multiple keyboards to bypass USB 6-key limit
• Present Tessel as a keyboard via Bluetooth module (lower priority)
• Run express + socket.io on Tessel, provide Web UI to:
  • Map GPIO pin to specific NKRO row or column (hopefully 1 time configuration)
  • Map row + column combination to specific key
    • Ability to edit/save/load profiles
  • Set up macros (lower priority)
  • Layout keys physically (drag-n-drop) for visualization purposes
    • Ability to edit/save/load layouts
  • Toggle actually sending keys to host (for debugging purposes)
  • Force pin/row/column state
  • Display real-time status information:
    • Pin/row/column/key state (on, off, mode, etc.). 3 views:
      • Tessel view (shows pin state)
      • Grid view (shows row state and column state)
      • Custom layout view (shows key state (mapped row + column combination)
    • Each view is actually 2 views: graphical and textual
      • This means the custom layout view will essentially be a keylogger
