General Description:

|
|
This file is an example configuration (with inline documentation) for the USB
|
|
|
|
|
driver. It configures V-USB for USB D+ connected to Port D bit 2 (which is
|
|
|
|
|
also hardware interrupt 0 on many devices) and USB D- to Port D bit 4. You may
|
|
|
|
|
wire the lines to any other port, as long as D+ is also wired to INT0 (or any
|
|
|
|
|
other hardware interrupt, as long as it is the highest level interrupt, see
|
|
|
|
|
section at the end of this file).

/* ------------------- Fine Control over USB Descriptors ------------------- */
|
|
|
|
|
/* If you don't want to use the driver's default USB descriptors, you can
|
|
|
|
|
* provide our own. These can be provided as (1) fixed length static data in
|
|
|
|
|
* flash memory, (2) fixed length static data in RAM or (3) dynamically at
|
|
|
|
|
* runtime in the function usbFunctionDescriptor(). See usbdrv.h for more
|
|
|
|
|
* information about this function.
|
|
|
|
|
* Descriptor handling is configured through the descriptor's properties. If
|
|
|
|
|
* no properties are defined or if they are 0, the default descriptor is used.
|
|
|
|
|
* Possible properties are:
|
|
|
|
|
* + USB_PROP_IS_DYNAMIC: The data for the descriptor should be fetched
|
|
|
|
|
* at runtime via usbFunctionDescriptor(). If the usbMsgPtr mechanism is
|
|
|
|
|
* used, the data is in FLASH by default. Add property USB_PROP_IS_RAM if
|
|
|
|
|
* you want RAM pointers.
|
|
|
|
|
* + USB_PROP_IS_RAM: The data returned by usbFunctionDescriptor() or found
|
|
|
|
|
* in static memory is in RAM, not in flash memory.
|
|
|
|
|
* + USB_PROP_LENGTH(len): If the data is in static memory (RAM or flash),
|
|
|
|
|
* the driver must know the descriptor's length. The descriptor itself is
|
|
|
|
|
* found at the address of a well known identifier (see below).
|
|
|
|
|
* List of static descriptor names (must be declared PROGMEM if in flash):
|
|
|
|
|
* char usbDescriptorDevice[];
|
|
|
|
|
* char usbDescriptorConfiguration[];
|
|
|
|
|
* char usbDescriptorHidReport[];
|
|
|
|
|
* char usbDescriptorString0[];
|
|
|
|
|
* int usbDescriptorStringVendor[];
|
|
|
|
|
* int usbDescriptorStringDevice[];
|
|
|
|
|
* int usbDescriptorStringSerialNumber[];
|
|
|
|
|
* Other descriptors can't be provided statically, they must be provided
|
|
|
|
|
* dynamically at runtime.
|
|
|
|
|
*
|
|
|
|
|
* Descriptor properties are or-ed or added together, e.g.:
|
|
|
|
|
* #define USB_CFG_DESCR_PROPS_DEVICE (USB_PROP_IS_RAM | USB_PROP_LENGTH(18))
|
|
|
|
|
*
|
|
|
|
|
* The following descriptors are defined:
|
|
|
|
|
* USB_CFG_DESCR_PROPS_DEVICE
|
|
|
|
|
* USB_CFG_DESCR_PROPS_CONFIGURATION
|
|
|
|
|
* USB_CFG_DESCR_PROPS_STRINGS
|
|
|
|
|
* USB_CFG_DESCR_PROPS_STRING_0
|
|
|
|
|
* USB_CFG_DESCR_PROPS_STRING_VENDOR
|
|
|
|
|
* USB_CFG_DESCR_PROPS_STRING_PRODUCT
|
|
|
|
|
* USB_CFG_DESCR_PROPS_STRING_SERIAL_NUMBER
|
|
|
|
|
* USB_CFG_DESCR_PROPS_HID
|
|
|
|
|
* USB_CFG_DESCR_PROPS_HID_REPORT
|
|
|
|
|
* USB_CFG_DESCR_PROPS_UNKNOWN (for all descriptors not handled by the driver)
|
|
|
|
|
*
|
|
|
|
|
* Note about string descriptors: String descriptors are not just strings, they
|
|
|
|
|
* are Unicode strings prefixed with a 2 byte header. Example:
|
|
|
|
|
* int serialNumberDescriptor[] = {
|
|
|
|
|
* USB_STRING_DESCRIPTOR_HEADER(6),
|
|
|
|
|
* 'S', 'e', 'r', 'i', 'a', 'l'
