Getting Started

2.1.2 Reprogramming the Microcontroller

Either or both the main PIC18F8722 microcontroller and RS-232-USB, or the

PIC18LF2450 microcontroller, can be reprogrammed for running the board as a

stand-alone device.

To implement this usage:

1. Reprogram either or both devices, as described in Section 2.4 “Programming

the Microcontrollers”.

2. Disconnect the programming devices.

3. Follow the procedure given in Section 2.1.1 “Using the Board As Is”.

2.2 BOARD WITH IN-CIRCUIT DEBUGGER

The PICDEM PIC18 Explorer Demonstration Board can also be connected to an

In-Circuit Debugger (ICD) that is connected to a host PC. This can be done with the

board’s main microcontroller configured as either the mounted PIC18F8722 device or

an alternate device mounted to a PIM that is plugged into the board. (For information

on PIM attached devices, see Section 2.3 “Board with PIM Attached Devices”.)

The MPLAB

ICD 2 In-Circuit Debugger is an inexpensive ICD that could be used. (For

more information, see Section 2.4.1 “Programming Requirements”.) The ICD is

connected, as shown in Figure 2-3, to the ICD connector. For operational information,

see “MPLAB

ICD 2 In-Circuit Debugger User’s Guide” (DS51331).

The PICDEM™ PIC18 Explorer Demonstration Board can alternately use the MPLAB

REAL ICE™ Emulator as a debugger. For more information, see the “Microchip

Development Systems Ordering Guide” (DS30177).
