File Information
Description

Data Acquisition Toolbox™ software provides a complete set of tools for analog input, analog output, and digital I/O from a variety of PC-compatible data acquisition hardware.

Support for the National Instrument USB-TC01 device was added to Data Acquisition Toolbox in R2011b. If you have R2010b or R2011a, you can use this file plus the Data Acquisition Toolbox to collect data from this device.

obj = TC01(deviceID,probeType) creates an object OBJ representing the device with the DEVICEID assigned by the National Instruments Measurement and Automation Explorer, with the PROBETYPE of 'J','K','T', etc. representing the type of the thermocouple used.

Call the READ method one or more times on the object to retrieve the current temperature in Celsius. The first time this is called, there will be a short delay as the hardware is configured, but additional calls will go faster.

This requires the Data Acquisition Toolbox and MATLAB R2010b or later. Note that this object takes exclusive access to the hardware. To release it, clear the variable that the object is assigned to.

Example:
  myTemp = TC01('Dev4','J');
 
  read(myTemp)
     ans =
        20.9406
    
  % release the hardware
  clear myTemp

I am currently attempting to use this code on MatLab2014a and i continually get this error "Undefined variable "daq" or class "daq.ni.ThermocoupleType.setValue"." any hints on what to do next?
