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".
|
|
