USB Device Interface (UDI) for Vendor Class

Common APIs used by high level application to use this USB class.

These routines are used to transfer data to/from USB VENDOR endpoints.

bool udi_vendor_bulk_in_run	(	uint8_t *	buf,
		iram_size_t	buf_size,
		udd_callback_trans_t	callback
	)

Start a transfer on bulk IN.

When the transfer is finished or aborted (stall, reset, ...), the callback is called. The callback returns the transfer status and eventually the number of byte transfered.

Parameters

buf	Buffer on Internal RAM to send or fill. It must be align, then use COMPILER_WORD_ALIGNED.
buf_size	Buffer size to send or fill
callback	NULL or function to call at the end of transfer

Returns

1 if function was successfully done, otherwise 0.

When the transfer is finished or aborted (stall, reset, ...), the callback is called. The callback returns the transfer status and eventually the number of byte transfered.

Parameters
