4 File: usbhidio_fx2.c
5 Contents: Hooks required to implement USB peripheral function.
6
7 This is an adaptation of the Cypress example FX2_Hid_Keyboard.c,
8 which was in turn adapted from Cypress's bulkloop.c
9 (and is available on request from Cypress).
10
11 The application communicates with the usbhdio host applications available from:
12
13 www.Lvr.com/hidpage.htm
14
15 This code requires the full (not evaluation) version of the Keil compiler.
16 Additions to the keyboard code are labeled with "usbhidio start" and "usbhidio end"
17 Unneeded keyboard code is commented out.
