define UDC_DESC_STORAGE
Defines the memory's location of USB descriptors.
By default the Descriptor is stored in RAM (UDC_DESC_STORAGE is defined empty).
If you have need to free RAM space, it is possible to put descriptor in flash in following case:
-
USB driver authorize flash transfer (USBB on UC3 and USB on Mega)
-
USB Device is not high speed (UDC no need to change USB descriptors)
For UC3 application used "const".
For Mega application used "code".
