|
|
|
|
Registers a callback to call when endpoint halt is cleared.
|
|
|
|
#### Parameters
|
|
* `ep` The ID of the endpoint to use
|
|
|
|
* `callback` NULL or function to call when endpoint halt is cleared
|
|
|
|
if the endpoint is not halted then the *callback* is called immediately.
|

#### Returns
|
|
`1` if the register is accepted, otherwise `0`.

|
|
|
|
Allows to receive or send data on an endpoint.
|
|
|
|
The driver uses a specific DMA USB to transfer data from internal RAM to endpoint, if this one is available. 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. Note: The control endpoint is not authorized.
|
|
|
|
#### Parameters
|
|
* `ep` The ID of the endpoint to use
|
|
|
|
* `b_shortpacket` Enabled automatic short packet
|
|
|
|
* `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
|
|
|
|
About *b_shortpacket*, for IN endpoint it means that a short packet (or a Zero Length Packet) will be sent to the USB line to properly close the usb transfer at the end of the data transfer. For Bulk and Interrupt OUT endpoint, it will automatically stop the transfer at the end of the data transfer (received short packet).

#### Returns
|

`1` if function was successfully done, otherwise `0`.
