Microchip: DM240315-2 Remote Control Demo Board

Kit Overview   The RF based Remote Controls are becoming more prevalent as they enable non line-of-sight and provide bi-directional communication. A high-end remote control typically has a graphics display, a number of keys and a radio to communicate with the target devices.   The Microchip’s Remote Control Demo Board (DM240315-2DM240315-2) integrates Graphics, mTouch, USB and RF4CE into a single demo. The board demonstrates a remote populated with PIC24FJ256DA210PIC24FJ256DA210 MCU, 3.5" Graphical TFT LCD with resistive touch screen, capacitive touch keys with plastic overlay, MRF24J40MRF24J40 2.4 GHz transceiver and ZENATM wireless Adapter.   The Microchip's Remote Control Demo Board(DM240315-2DM240315-2) is preprogrammed with the complete firmware to demonstrate all remote control commands. In order to explore this software and the interface between the controller and the target of the ZENA Wireless Adapter, you will need to install software and pair the remote to the target. This section describes the basic features of the hardware included, and provides instructions for how to pair the Remote Control Demo Board and the ZENA Wireless Adapter.   Hardware The Remote Control Demo Board(DM240315-2DM240315-2) has a 3.5” QVGA display with a resistive touch screen in portrait mode, 11 mTouch Solution Capacitive Touch keys, five-way joy stick and a MRF24J40MAMRF24J40MA transceiver. A PIC24FJ256DA210PIC24FJ256DA210 controls these features.   Benefits of the Demonstration Combines graphics, mTouch, USB and RF4CE High system integration with PIC24 “DA” family Simple hardware layout Integrated software libraries Schematics, BOM and source code   Key Applications: Consumer Electronics
