* 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().
|
|
* + 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[];
|

|
|
* 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))
