DeviceConfigure

DeviceConfigure[device,config]

configures the specified device according to config.

Details

  • The configuration specification config is often a list of rules or an association of values.
  • DeviceConfigure typically changes device properties.
  • A device can be specified either by a DeviceObject or by a string representing a device class.
  • DeviceConfigure can be called multiple times for a given device.
  • DeviceConfigure[device,config] returns config, even if for some reason the operation fails.

Examples

Basic Examples  (1)

Use DeviceConfigure to set the buffer length for a demo device:

Wolfram Language code: DeviceConfigure["RandomSignalDemo", "BufferLength" -> 8];

Verify the setting:

Wolfram Language code: DeviceReadBuffer["RandomSignalDemo"]
Wolfram Language code: Length[%]

Applications  (3)

Use DeviceConfigure to set the pin directions for a GPIO device (e.g. on Raspberry Pi):

Wolfram Language code: DeviceConfigure["GPIO", {4 -> "Output", 17 -> "Input"}];

Read the digital value on pin 17:

Wolfram Language code: DeviceRead["GPIO", 17]

Set pin 4 to digital "High":

Wolfram Language code: DeviceWrite["GPIO", 4 -> 1]

Capture a frame from the system camera:

Wolfram Language code: dev = DeviceOpen["Camera"];
Wolfram Language code: DeviceRead[dev]

Modify the default raster size using DeviceConfigure and read another frame with the new setting:

Wolfram Language code: DeviceConfigure[dev, "RasterSize" -> {100, 100}];
Wolfram Language code: DeviceRead[dev]

Open a connection to a weather station device and configure its barometer bricklet UID:

Wolfram Language code: dev = DeviceOpen["TinkerForgeWeatherStation"]
Wolfram Language code: DeviceConfigure[dev, "BarometerBrickletUID" -> "g2h"];

Read in the ambient pressure from the configured device:

Wolfram Language code: DeviceRead[dev, "Pressure"]

Properties & Relations  (1)

DeviceConfigure can change properties of the device after it is open:

Wolfram Language code: dev = DeviceOpen["RandomSignalDemo"]
Wolfram Language code: dev["BufferLength"]
Wolfram Language code: DeviceConfigure[dev, "BufferLength" -> 2];
Wolfram Language code: dev["BufferLength"]
