Chapter 1. Using the USB Device Firmware Framework
HIGHLIGHTS
OVERVIEW OF THE FRAMEWORK
The items discussed in this chapter are:
• Overview of the Framework
• USB Device Firmware in the Framework
The Microchip USB Device Firmware Framework is a library that can be used to create
new USB applications. It can be thought of as a reference design project, containing
the necessary firmware code for USB operation and providing a placeholder for the
user’s code. The whole code project is contained within one single root project
directory, with many subdirectories for source code organization.
The USB Framework is based on the latest versions (as this is written) of Microchip’s
development tools. To provide the best level of USB application support, you should
verify that you have at least these revisions of the following tools before starting:
• MPLAB
• Microchip C30 C Compiler, v 3.02 or later; or Microchip C18 C Compiler, v3.10 or
This section describes the importance in setting up the project paths and how the
Framework is organized.
1.2.1
The Framework is designed in such a way that files located in the Microchip directory
do not need modification. All files that need to be modified by the user are located in
the <Application> folder. The directory structure of the USB Device Firmware
Framework is the following:
