Mex-File Utility for Fast MATLAB Port I/O (64-bit) Mex-File Plug-in for Fast MATLAB Port I/O (64-bit Windows XP, Vista, 7,8,10) Windows Vista and Windows 7 users should note the Vista/7 Installation Notes near the end of this document. A version of this software for 32-bit Windows can be found. A version of this software for running 32-bit MATLAB on 64-bit Windows can be found. In order to accomplish very fast port I/O using a NO COST add-on to MATLAB, we have developed a C++ extension (mex-file) that uses native methods to access low-level hardware. This mex-file is named io64.mexw64.

It uses a freeware self-installing system driver named inpoutx64.dll. [ Note: Self-installation of the driver requires that the MATLAB runs with Administrator privileges. The driver must have been previously installed in order to support non-Administrator users]. To install this expanded capability: download the module and move it to a directory in your MATLAB path (e.g., c: cog2000 Cogent2000v1.29 Toolbox in the case of the USD PSYC 770 standard Cogent 2000 64-bit Windows installation).

Now I do have a new computer with windows 7 OS.The problem is that when I try to install the drivers for the parallel port PORT95NT, says that. Windows Client: XP / Vista / 7 / 8.x / 10 (X86/X64) • Windows Server. * ECP / EPP / SPP / BPP modes work under Windows, and Linux driver only supports SPP mode. Manual, Parallel LPT Port Read-Writer Register User Guide.

Next, download the module and move it to the C: windows system32 directory (i.e., This module must reside in the Windows system PATH). Special Note: Because the inpoutx64.dll was compiled using Visual Studio, the Microsoft Visual C++ 2005 SP1 Redistributable (x64) Package must be installed on your computer. Use the Control Panel to see if it is already installed. If not, the installer application can be downlaoded from Microsoft at io64() Command Usage Summary: object = io64; Calling io64 with no input arguments creates a persistent instance of the io64 interface object and returns a 64-bit handle to its location. This command must be issued first since the object handle is a required input argument for all other calls to io64.

This io64 call will not work properly unless a return variable is specified (i.e., 'object' in the example to the left). Status = io64( object ); Calling io64() using one input argument and a single return variable causes the inpoutx64.sys kernel-level I/O driver to be automatically installed (i.e., no manual driver installation is required). Object is the handle to a previously created instance of io64 (see the step performed above); and, status is a variable returned from the function that describes whether the driver installation process was successful (0 = successful). Subsequent attempts to perform port I/O using io64() will fail if a non-zero status value is returned here. This step must be performed prior to any subsequent attempts to read or write I/O port data. Io64( object, address, data ); Calling io64() with three input parameters allows the user to output data to the specified I/O port address. Object is the handle to an io64 object (described above); address specifies the physical address of the destination I/O port (.

Hi I need some urgent assistance. I make use of Altium Designer software.

However since I have upgraded from Windows XP to Windows 7 64-bit Professional I cannot run my software. I receive an error 'Parallel Port Driver is not Supported by 64-bit Windows'.

In order to provide the best platform for continued innovation, Jive no longer supports Internet Explorer 7. Jive will not function with this version of Internet Explorer. Convert sldprt files to dxf. Attention, Internet Explorer User Announcement: Jive has discontinued support for Internet Explorer 7 and below.

According to Altium Designer support this is a Windows problem. They suggested running the program in Compatibility View but this also comes up with the same error. I use to run my programs on Windows XP without any problems or errors. Please assist me with a solution as to how to fix this error. Hello DatTran, Welcome to Microsoft Community Forum.
