LESSON 1: HELLO LED
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™.
This first lesson shows how to create a MPLAB C compiler project in the MPLAB
and turn on a demo board LED using the PIC18F45K20.
3.1.1
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
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.
