Summary:
This file contains functions, macros, definitions, variables,
datatypes, etc. that are required for usage with the MCHPFSUSB device
stack. This file should be included in projects that use the device stack.

directory.
Description:
USB Device Stack File
This file contains functions, macros, definitions, variables,
datatypes, etc. that are required for usage with the MCHPFSUSB device
stack. This file should be included in projects that use the device stack.
This file is located in the "\<Install Directory\>\\Microchip\\USB"
directory.
When including this file in a new project, this file can either be
referenced from the directory in which it was installed or copied
directly into the user application folder. If the first method is
chosen to keep the file located in the folder in which it is installed
then include paths need to be added so that the library and the
application both know where to reference each others files. If the
application folder is located in the same folder as the Microchip
folder (like the current demo folders), then the following include
paths need to be added to the application's project:
.
..\\..\\MicrochipInclude
If a different directory structure is used, modify the paths as
required. An example using absolute paths instead of relative paths
would be the following:
C:\\Microchip Solutions\\Microchip\\Include
C:\\Microchip Solutions\\My Demo Application

File Description:
Change History:
Rev Description
---- -----------
2.8 Initial revision. Contents extracted from the previous usb_device.c
file, so as to make the usb_device.c file less cluttered.
Fixed BD() and EP() macro computation error, when running in
USB_PING_PONG__EP0_OUT_ONLY mode.
2.9 No functional change. Fixed spelling typo in the name of
"USB_TRANSFER_COMPLETE_HANDLER()"
