Generic_HID Firmware for Microchip Full-speed USB Chips

This application is a generic HID device (not a system
keyboard or mouse) that does the following:
Receives Output reports using interrupt OUT transfers and
sends the report data back to the host in Input reports
using interrupt IN transfers.
Receives Output reports using control transfers (Set_Report
request) and sends the report data back to the host in Input
reports using control transfers (Get_Report requests.)
The application uses separate buffers for Output reports
received via interrupt transfers and Output reports received
via control transfers use separate buffers. The application
uses separate buffers for Input reports received via
interrupt transfers and Input reports received via control
transfers.
Receives Feature reports using control transfers (Set_Report
request) and sends the report data back to the host in
Feature reports using control transfers (Get_Report
requests.)
A single buffer holds received Feature reports and reports
to be sent.
This example is adapted from Microchip's Mouse example.
The project has been tested on the PICDEM?FS USB
DEMONSTRATION BOARD
The project files should be at C:\MCHPFSUSB_generic_hid. If
you want to change the location, see section 4.2.3 in the
PICDEM FS USB User’s Guide.
This application and host applications to communicate with
the device are available from www.Lvr.com/hidpage.htm
