• Download example HID code from Keil website: http://www.keil.com/download/docs/306.asp
• Make changes in the InReport size and a structure can be used to store the data format.
• Configure the USB descriptors as explained in the project details.

PCB can be designed for the remote on the transmitter side (breadboard  would also work). Make the necessary connections using the encoder and push buttons to transmit data through RF.

On the LPC, interface the RF receiver with the GPIO pins.

Connect LPC with PC and flash the remote.c code. Disconnect and reconnect the LPC. The device must now be shown as a keyboard in Device Manager and can be directly used to change slides.
