Hi I have a MATLAB R2015a using 64bit windows. I also have the Data Acquisition toolbox. While running digitalio('parallel', 'LPT1'), it send an error: "Error using digitalio (line 40) The DAQ Legacy Interface is not supported on this platform...."
What should I do to control the LPT1 under this version and 64bit machine
Thanks Rafi

As the error message suggests, "digitalio" is a Legacy interface function and Legacy interface is not supported on 64-bit MATLAB.
This is also mentioned in the documentation page:

In order to use Legacy interface use 32-bit MATLAB
