Chapter 2. The XLP Demonstration Application

This chapter describes the demonstration application that is preprogrammed on the
PIC24F microcontroller, which shows the use of low-power techniques in a working
application. In the process, the application highlights various features of the PIC24F
microcontroller family.
2.1

INITIAL SETUP

Although intended as a development platform, the XLP 16-bit board is also designed
to be used directly from the box as a demonstration platform. The demonstration
firmware preprogrammed into the PIC24F16KA102 microcontroller is ready for
immediate use.
The demonstration firmware uses a USB to RS-232 converter to communicate with the
PC via a standard serial interface. In order to use the board with a PC, a serial terminal
program will be required.
2.1.1
To get started with the board, verify that it is properly configured:
1. Verify the PIC24F16KA102 is correctly installed into socket, U1. The notch on the
2. Verify that S4 is in the "PIC24K" position.
3. Ensure the IC PWR switch is in the "RB2" position.
4. Populate the PIC
5. Select "EXT PS/USB" with the power source select jumper.
6. Select the "MCP9700" temperature sensor option with the temp sense jumper.
7. Populate the TEMP, SEE and POT jumpers.
2.1.2
Before connecting the board to the PC for the first time, install the USB Serial Converter
driver. The instructions for this process are provided with the XLP 16-bit Development Kit
source code distribution, which is available at: http://www.microchip.com/xlp16bitboard.
After the installation completes, connect the development board to the PC with the
provided USB cable (A to mini-B). The USB to RS-232 converter (implemented using
the PIC18F14K50) will be assigned a comm port number. Use the utilities provided by
the PC's operating system to determine the comm port number assigned to the
converter.
