DeviceExecute

DeviceExecute[device,"command"]

executes the specified command on a device.

DeviceExecute[device,"command",params]

executes the command with the parameters params.

Details

  • A device can be specified either by a DeviceObject or by a string representing a device class.
  • DeviceExecute is a blocking function; when called, it communicates with the device and does not return until it has the data it needs.
  • The parameters params can be given either as a list of raw parameters or as an association or list of rules giving names and values of parameters.
  • DeviceExecute returns a Wolfram Language version of the result of executing the specified command on the device.

Basic Examples  (2)

Open a demo device and execute a command on it:

Wolfram Language code: dev = DeviceOpen["FunctionDemo"]
Wolfram Language code: DeviceExecute[dev, "Date"]

Specify a device class to execute the same command:

Wolfram Language code: DeviceExecute["FunctionDemo", "Date"]

Execute a command with a specified parameter:

Wolfram Language code: command = "DayName";params = {Today};
Wolfram Language code: DeviceExecute["FunctionDemo", command, params]

Applications  (2)

Open a weather station and write a string to its LCD screen:

Wolfram Language code: dev = DeviceOpen["TinkerForgeWeatherStation"]
Wolfram Language code: DeviceConfigure[dev, "LCDBrickletUID" -> "gLp"];DeviceWrite[dev, "This is a string"];

Use DeviceExecute to clear the screen:

Wolfram Language code: DeviceExecute[dev, "ClearLCDDisplay"]

Write a string of bytes to a Sphero serial device and use DeviceExecute to check if a response is available:

Wolfram Language code: dev = DeviceOpen["SerialDemo", "*Sphero*"]
Wolfram Language code: DeviceWrite[dev, FromCharacterCode[{255, 255, 0, 1, 5, 1, 248}]];
Wolfram Language code: DeviceExecute[dev, "SerialReadyQ"]

Flush the buffered data and check that the buffer is empty:

Wolfram Language code: DeviceExecute[dev, "ReadFlush"]
Wolfram Language code: DeviceExecute[dev, "SerialReadyQ"]
