PC compatible USB HID keyboard operated remotely from Android phone via Bluetooth.

===== Motivation =====
  - To learn and play around with LPCxpresso 1343 and its USB capabilities.
  - To create an usefull peripheral.

===== Use case scenarios ====
Me laying in the bed operating MPlayer running on PC via android phone.
Target price: not more than 400 CZK (30 USD)

===== Specification =====
   * Selected technologies:
     * AKeyboard Device Hardware:
         * MCU: [[http://ics.nxp.com/products/lpc1000/lpc13xx/~LPC1343/| NXP LPC1343]]
         * Bluetooth module: [[http://www.rayson.com/btm110.html|BTM-112]]
         * Plastic box: To be produced on RepRap.
     * AKeyboard Device Software:
         * Compiler: [[http://www.gnuarm.com/|gnuarm(GCC)]]
         * SDK: [[http://www.microbuilder.eu/|microbuilder]]
     * AKeyboard Controller:
         * All bluetooth-enabled Android 2.0+ phones.


===== Phases of project =====
==== Preparation ====
  - Create this page - **DONE**
  - Create GIT repository - **DONE**
  - Test communication with BT module via UART - **DONE**
  - Explore USB-CDC capabilities - **DONE**
  - Make HID keyboard working example - **DONE**
  - Make HID mouse working example - **DONE**

==== Implementation ====
  - Write software part for USB HID Keyboard on MCU - **DONE**
  - Write software part for USB HID Mouse on MCU - **DONE**
  - Bridge HID and Bluetooth channels. - **DONE**
  - Create Android application for 101-keyboard. - **DONE**
  - Create Android application for Mouse. - **IN PROGRESS**
  - Draw hw schema. - **DONE**
  - Draw PCB. - **IN PROGRESS**
  - Buy parts
  - Edge PCB
  - Solder 10 pcs
  - Print box for device on RepRap - **TO BE SKIPPED/TOO FANCY**
  - Improve Android application to support different keyboard layouts for different applications. Users should be able to create their own keyboard layouts. For instance Photoshop/Microsoft Word/Eagle  shortcuts.


==== Notes ============
  - LPC USB HID ROM cannot be used since the hid device subclass is hard coded.
  - I need to find out how to put hid keyboard to idle state, otherwise it is flooding my usb bus
  - Why make special hardware for this? All you need is bluetooth (or wifi) dongle and custom software (well, you can already find such software: bemused, remotedroid, vnc) and mouse/keyboard is even part of bluetooth specification (with proper software your mobile phone can behave as keyboard without need for non-standart software/drivers on PC)
