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
