MPORT

This is a MEX-file for MATLAB enabling to perform input and output CPU instructions (input/output port access) within Matlab running on Windows OS. Thanks to this you can access for example parallel (LPT) port and control your hardware.

MATLAB call examples:
   mport('state')
   mport('inpout')
   mport('winring0')
   mport('out', address, dataout)
   [data] = mport('in', address)
   [data] = mport('in', address, count)
   [data] = mport('inout', address, dataout)
   mport('out16', address, dataout)
   ...
