| Large Descriptor |
 Posted: Tue May 21, 2019 9:08 am |
 |
|
What do I need to change to use a descriptor greater than 255 bytes?
| Code: | //if a class has an extra descriptor not part of the config descriptor,
// this lookup table defines the size of that descriptor.
//first element is the config number (if your device has more than one config)
//second element is which interface number
//set element to 0xFFFF if this config/interface combo doesn't exist
const int16 USB_CLASS_SPECIFIC_DESC_LOOKUP_SIZE[USB_NUM_CONFIGURATIONS][3] =
{
//config 1
//interface 0
63,
//interface 1
32,
//interface 2
>256//large descriptor part here
}; |
I want to try to implement force feedback. |

Er. You can't.
The first byte of a USB descriptor, is it's length. A one byte value.
So all USB descriptors are inherently limited to 255 bytes or less.
(since this can only give 1 to 255 as a length).
Why on earth do you think force feedback requires a > 255 byte descriptor?.

If you look at the code you are copying from, the descriptor size is just
64bytes. The big block is the report. |

| yes, you can though I can't help as I stay away from USB...too dang slow, too complicated and NOT interrupt driven. |

Sorry Jay, but for a force feedback joystick, USB is the only solution.
and (of course) USB is interrupt driven. It's just that there is not a nice
simple interrupt for an event. Instead the handler has to interpret the
packet and work out what it is.
Now on this, the data here is the report descriptor. It contains separate
descriptors for a huge number of different possible packets that the
stick can generate (I count about 23...). This goes into the block starting:
const char USB_CLASS_SPECIFIC_DESC[] =
Have a look at the example for multihid, which shows a larger class
descriptor. |
