DEFINING PROJECT DESCRIPTORS
The enumeration.c file’s ProcessIO() is empty. Therefore, this application will do
nothing. The intention of this lab is to introduce the user to properly configure the firm-
ware so that the PIC18F14K50 will enumerate as a HID mouse once connected to the
Host PC. Therefore, the usb_descriptors.c file will need to be altered accordingly.
As a reference, the USB Revision 2.0 specification should be opened to Section 9-5
“Descriptors”. This section details the various components required in each type of
descriptor (device, configuration, interface etc…). This usb_descriptor.c file
should be an exact replica of the source file of the same name found in the Framework
folder
C:\Microchip Solutions\USB Device - HID - Mouse\HID - Mouse –
Firmware\usb_descriptor.c
This file can be used as a reference during debugging.
16. In the MPLAB IDE Project window, select and open the usb_descriptors.c
source file.
Note #include "./USB/usb_function_hid.h" at the top of the file. If a
different class of device is being defined for a given application, the appropriate
class header file will need to be included here.
