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.

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

Start a transfer on bulk OUT.

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.

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

Start a transfer on interrupt 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_size	Buffer size to send or fill
callback	NULL or function to call at the end of transfer
