Remember: You must not inject a signal into the ICD 3 when it is not powered. This means that the ICD 3 must be connected to the host PC first and disconnected last. The MPLAB X integrated development environment (IDE) software is installed and configured before you begin this tutorial. In the Mechatronics Lab we will always power the ICD 3 from the USB cable that connects it to the host PC. An external power supply will always be used to power the target board (the PICDEM 2 Plus Demo Board for this tutorial). Make a new directory ‐ say Demo ‐ in the directory that you created in step 1. 1.ĭepending on whether you are working alone for this tutorial, or with a lab partner, follow the instructions in section 1.1 of the “Mechatronics Laboratory – Facilities” document to either a.Ĭreate a personal directory on the U: drive (\\mxlabserver\Users) ORĬreate and assign permissions to a directory on the V: drive (\\mxlabserver\Groups) that you can share with your lab partner. You must always (and only) store your files on the File Server, mxlabserver. For this tutorial, the first thing that you must do is create a directory on the File Server to work in. In the Mechatronics Lab we may update the image on the computers at any time without warning. This means that any files that you have stored locally on a Mx Lab PC will be destroyed. Topics covered in this tutorial: Creating a directory on the Lab fileserver Setting up the development environment Creating and configuring a project Adding source files to the project Building the project Debugging the project Programming the application TUT452.asm source code This tutorial walks you through the process of developing a simple project using a sample program, TUT452.asm. This program uses the analog‐to‐digital (A/D) converter of the PIC18F452 on the PICDEM 2 Plus Demo Board (DM163022). The program configures the A/D module to convert input from A/D channel 0 (connected to the potentiometer on the demo board) and display the results as a binary number on the four PORTB LEDs.

MPLAB X / ICD 3 Tutorial This document is adapted for MPLAB X and the ICD 3 In‐circuit Debugger from the tutorials that form chapter 3 of the “MPLAB ICD 2 In‐Circuit Debugger User’s Guide” and chapter 3 of the “MPLAB ICD 3 In‐Circuit Debugger User’s Guide”.
