Open Lighting Architecture 0.10.9
|
A base class that implements common functionality to send or receive DMX asynchronously to a libusb_device.
Public Member Functions | |
| AsyncUsbTransceiverBase (ola::usb::LibUsbAdaptor *const adaptor, libusb_device *usb_device) | |
| Create a new AsyncUsbTransceiverBase. | |
| virtual | ~AsyncUsbTransceiverBase () |
| Destructor. | |
| bool | Init () |
| Initialize the transceiver. | |
| virtual void | TransferComplete (struct libusb_transfer *transfer)=0 |
| Called from the libusb callback when the asynchronous transfer completes. | |
| libusb_device_handle * | GetHandle () |

Protected Types | |
| enum | TransferState { IDLE , IN_PROGRESS , DISCONNECTED } |
Protected Member Functions | |
| virtual libusb_device_handle * | SetupHandle ()=0 |
| Open the device handle. | |
| virtual void | PostTransferHook () |
| Called when the transfer completes. | |
| void | CancelTransfer () |
| Cancel any pending transfers. | |
| void | FillControlTransfer (unsigned char *buffer, unsigned int timeout) |
| Fill a control transfer. | |
| void | FillBulkTransfer (unsigned char endpoint, unsigned char *buffer, int length, unsigned int timeout) |

| ola::plugin::usbdmx::AsyncUsbTransceiverBase::AsyncUsbTransceiverBase | ( | ola::usb::LibUsbAdaptor *const | adaptor, |
| libusb_device * | usb_device ) |
Create a new AsyncUsbTransceiverBase.
| adaptor | the LibUsbAdaptor to use. |
| usb_device | the libusb_device to use for the widget. |
|
protected |
Fill a control transfer.
| buffer | passed to libusb_fill_control_transfer. |
| timeout | passed to libusb_fill_control_transfer. |
|
inline |
Get the libusb_device_handle of an already opened widget.
| bool ola::plugin::usbdmx::AsyncUsbTransceiverBase::Init | ( | ) |
Initialize the transceiver.
|
inlineprotectedvirtual |
Called when the transfer completes.
Some devices require multiple transfers per DMX frame. This provides a hook for continuation.
Reimplemented in ola::plugin::usbdmx::AsyncUsbSender, ola::plugin::usbdmx::DMXCProjectsNodleU1AsyncUsbSender, and ola::plugin::usbdmx::VellemanAsyncUsbSender.
|
protectedpure virtual |
Open the device handle.
Implemented in ola::plugin::usbdmx::AnymaAsyncUsbSender, ola::plugin::usbdmx::DMXCProjectsNodleU1AsyncUsbReceiver, ola::plugin::usbdmx::DMXCProjectsNodleU1AsyncUsbSender, ola::plugin::usbdmx::EuroliteProAsyncUsbSender, ola::plugin::usbdmx::FadecandyAsyncUsbSender, ola::plugin::usbdmx::SunliteAsyncUsbSender, and ola::plugin::usbdmx::VellemanAsyncUsbSender.
|
