Low Pin Count USB Development Kit User’s Guide
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.
17. Scroll down to the device descriptor section and copy and paste the code in
Example 2-1 between the curly brackets in the section labeled:
//ADD DEVICE DESCRIPTOR CODE HERE
Note:
The user may wish to clean up the look of the code by spacing comment
sections accordingly. Tabs were ignored to ensure completeness for this
document.
