Procedure
This application requires significant changes to the usb_descriptor.c file to configure
the PIC18F14K50 as a CDC device. Note the absence of the report descriptor. The
user is encouraged to spend some time reviewing the usb_descriptor.c file and com-
pare it against the information found in the Universal Serial Bus Class Definitions for
Communications Devices document referenced at the beginning of this chapter. Note
that this lab applies the same firmware found in the CDC – Serial Emulator application
example in Microchip’s Full-Speed USB Firmware Framework application examples
and can be used as a reference for this lab.
1. Create a new project “Project Lab 4” as was done in the previous labs. The
2. Right click on the Source Files folder in the Project window and select Create
usb_descriptor.c and main.c source files for Lab 4 can be found in:
C:\LPCUSBDK_Labs\Lab4_files
This time, the project will be set up to resemble the application examples in the
Framework using sub-folders to distinguish and organize the different source
files in the Project window.
