DeviceReadList
This feature is not supported on the Wolfram Cloud.

DeviceReadList[device,n]
reads from the specified device n times, returning a list of the results.

DeviceReadList[device,n,param]
reads the parameter param.

DeviceReadList[device,n,{param1,param2,}]
reads the list of parameters .

DetailsDetails

  • DeviceReadList effectively performs n sequential reads on the device, as quickly as possible.
  • DeviceReadList[device,n] reads the default parameter from the device.
  • DeviceReadList is a blocking function; when called, it communicates with the device and does not return until it has the data it needs.
  • A device can be specified either by a DeviceObject or by a string representing a device class.
