PICkit™ 3 DEBUG EXPRESS

Chapter 3. PICkit™ 3 Debug Express Lessons

Connect the PICkit™ 3 Programmer/Debugger to a PC USB port, and connect the

demo board to the PICkit via header P1, labeled ICSP™.

3.1 LESSON 1: HELLO LED

This first lesson shows how to create a MPLAB C compiler project in the MPLAB

IDE

and turn on a demo board LED using the PIC18F45K20.

3.1.1 Creating the Lesson 1 Project in the MPLAB

IDE

Begin by opening the MPLAB IDE from the desktop shortcut icon:

To create project, use the MPLAB IDE Project Wizard by selecting the menu Project >

Project Wizard…. The Project Wizard “Welcome!” dialog is shown. Click Next to

continue.

3.1.1.1 STEP ONE: SELECT A DEVICE

In the Project Wizard dialog, select PIC18F45K20 as the target device in the dropdown

box, as shown in Figure 3-1, and click Next to continue.

Key Concepts

- Use the MPLAB IDE Project Wizard to create a new project for a microcon-

troller.

- The TRISx Special Function Registers (SFRs) are used to set microcon-

troller port I/O pin directions as inputs or outputs.

- The LATx SFRs are used to set microcontroller port output pins to a high or

low state.
