README

This code transforms an Olimex LPC-P1343 into an USB HID Keyboard input device. All that is needed is some switcches connected between the io pins and GND.

Requirements

• To compile and build you need the KEIL ARM (evaluation) tools.
• An Olimex LPC-P1343
• Some Switches (footswitch or other pushbutton switch ).
• Some Soldering skills...
• Optional : Keil ULINK2 JTAG Prgrammer.

How do I get set up?

• Connect the switches between GND and the io pins:

• P1.6 = Key 1

• P1.7 = Key 2

• P1.8 = Key 3

• P1.9 = Key 4

• P1.10= Key 5

• Compile and build the project.

• You can change the hardcoded keys in the GetInReport() function. See the USB [HID Spec] (http://www.usb.org/developers/hidpage/Hut1_12v2.pdf) page 53 for details.

Deployment instructions

Using ULINK2

• Make sure Jumper BLD_E is removed.
• Connect to the host PC.
• Download the code in the CPU
• Remove the JTAG and reset the board.

Without ULINK2

• Place the jumper BLD_E
• Connect to the host PC.
• The CPU will present itself as an USB disk in explorer.
• Copy the binairy to this new drive.
• Remove the power.
• Remove jumper BLD_E.
• Reconnect the power.(resetting also works without removing the usb cable first)
