Class Details¶

class Aravis.UvDevice(**kwargs)¶

Bases:: Aravis.Device
Abstract:: No
Structure:: Aravis.UvDeviceClass

classmethod new(vendor, product, serial_number)¶

Parameters:

vendor (str) – USB3 vendor string
product (str) – USB3 product string
serial_number (str) – device serial number

Raises:

GLib.Error

Returns:

a newly created Aravis.Device using USB3 based protocol

Return type:

Aravis.Device

New in version 0.8.0.

classmethod new_from_guid(guid)¶

Parameters:: guid (str) – device GUID
Raises:: GLib.Error
Returns:: a newly created Aravis.Device using USB3 based protocol
Return type:: Aravis.Device

New in version 0.8.17.

set_usb_mode(usb_mode)¶

Parameters:: usb_mode (Aravis.UvUsbMode) – a Aravis.UvUsbMode option

Sets the option to utilize the USB synchronous or asynchronous device I/O API. The default mode is Aravis.UvUsbMode.SYNC, which means USB bulk transfer will be synchronously executed. This mode is qualified to work, but it has the performance issue with some high framerate device. Using Aravis.UvUsbMode.ASYNC possibly improves the bandwidth.

New in version 0.8.17.
