PROJECT LAB 1 (ENUMERATION)

2.4.1

Purpose

The purpose of this lab is intended to introduce the user to creating a project in the

MPLAB IDE using Microchip’s Full-Speed USB Firmware Framework. Though many

application examples in the Framework can be used to create original code, building

the Framework from scratch is a great way to get familiar to the overall functionality of

this multitasking tool.

The user will create a project, ensure that the IDE is configured accordingly, and alter

the usb_descriptor.c file to enable the enumeration of the PIC18F14K50 as a HID

mouse device.

2.4.2

Procedure

2.4.2.1

BUILDING THE FRAMEWORK

Open the MPLAB IDE by selecting Start>Programs>Microchip>MPLAB IDE

vx.xx>MPLAB IDE

Once in the MPLAB IDE, start the Project Wizard by selecting Project>Project

Wizard

Select the PIC18F14K50 as the device, select the MPLAB C18 C Compiler as

the language toolsuite, and create a new project folder in the following directory:

C:\Microchip Solutions\Project Lab 1\Project Lab 1

Note:

In this and all subsequent project labs, the USB cable must be discon-

nected from the USB mini-B connector on the Low Pin Count USB Devel-

opment Board when programming with the PICkit 2 programmer.
