Using Connected Devices

The Wolfram Language provides a streamlined framework for connecting to external devices. Many classes of devices listed in the Wolfram Connected Devices Project are immediately supported within the Wolfram Language.

Setting Up Devices & Connections

DeviceOpen — open a connection to a device

DeviceObject — representation of a connected device

DeviceConfigure  ▪  DeviceClose  ▪  Devices

FindDevices — attempt to find devices available on a particular machine

device[param] — the value of a parameter for a device, often settable with  (Set)

Device Types

"Serial" — generic RS-232/RS-422 serial protocol

"GPIO" — general-purpose digital I/O directly from pins

"Vernier" — general interface to Vernier Go!Link compatible sensors

"Arduino" — Arduino analog and digital I/O and autonomous code execution

"Camera", "RaspiCam", ... — cameras for capturing images

"OpenAIGym", ... — reinforcement learning environment (video games, etc.)

Reading Unbuffered Data

DeviceRead — ask to read one item of data from a device, waiting until it is done

DeviceReadList — repeatedly read items of data a specified number of times

DeviceReadTimeSeries — read data at specified times, and construct a time series

Reading Buffered Data

DeviceReadLatest — read the most recently buffered piece of data from the device

DeviceReadBuffer — read the entire contents of the buffer on the device

Writing Unbuffered & Buffered Data

DeviceWrite — write a value or list of values to a device

DeviceWriteBuffer — write data to fill the buffer on a device

Executing Commands

DeviceExecute — execute a command on a device

DeviceExecuteAsynchronous — initiate an asynchronous command

Stream Interfaces for Devices

DeviceStreams — get streams associated with a device
