INTRODUCTION
This section of the user’s guide will walk the user through a number of project labs that
will ease the development of original USB design applications. Labs are formatted so
that the user is guided through each project’s source code to uncomment or copy and
paste sections of code. This format was chosen to force the developer to explore sig-
nificant sections of the Framework and familiarize themselves with the overall structure
of the source files presented.

Lab files can be located in the folder C:\LPCUSBDK_Labs\Labx_files. Each lab
folder will contain both the source files for the labs and a folder containing the solutions
with working code.

Four labs are presented:

Project Lab 2 (HID Mouse): This lab expands on concepts learned in Project Lab
1 using the descriptors defined. The user will walk through the development of
application specific functions within the mouse.c firmware file. The end applica-
tion will behave like a Human Interface Device Class (HID) mouse by moving the
pointer on the PC screen.

3.
Project Lab 3 (HID Keyboard): In this lab the user is required to alter the descrip-
tors to implement a HID keyboard-based application. The potentiometer on the
Low Pin Count USB Development Board is rotated to change the HID specifica-
tion unicode value transmitted through the USB to the PC that will print charac-
ters based on an ADC conversion.

Project Lab 4 (CDC Serial Emulator): Finally, the user will implement a
communication protocol converter using the Communication Device Class
