PICDEM ? HPC Explorer Board

Summary

The PICDEM HPC Explorer Board is the latest 64/80 TQFP demostration board for evaluating

Microchip Technology's PIC18F and PIC18FXXJXX families of devices. It comes populated with

a PIC18F8722 MCU. Direct connection support is available for the MPLAB ? ICE 2000 and

MPLAB ICE 4000 processor modules, plug-in modules and MPLAB ICD 2 In-Circuit Programmer.

Software

The PIC18F8722 MCU is preprogrammed with demonstration software which displays information

on the Windows ? HyperTerminal program via the serial port.

10K POT TC74 RESET MCU Enable

A/D Channel 0 Temperature Button Switch

RA0 Pin Sensor

MPLAB ? ICD 2

Connector

Use the following settings:

57600 baud

8 data bits

No Parity

1 Stop bit

No Flow Control

Autodetect terminal emulation

On power-up, PIC18F8722 will continuously display the LED states, potentiometer voltage, RB0

button state, temperature and relative time in minutes and seconds. NOTE: Pressing the RB0

button during power-up enables the bootloader. The LEDs can be toggled by pressing the 1

through 8 keys.
