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: NXP LPC1343
- Bluetooth module: BTM-112
- Plastic box: To be produced on RepRap.
- AKeyboard Device Software:
- Compiler: gnuarm(GCC)
- SDK: 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)
