DioPrint

Using the DIO Object and parallel port adaptor to emulate the Centronics Protocol to drive a printer

Description

This demo illustrates how you use MATLAB and the Data Acquisition Toolbox to emulate the Centronics protocol commonly used to communicate with parallel port devices.

The Centronics protocol is a set of rules that dictate the exchange of signals between a host and client device. This protocol ensures that information is passed in a correct and timely manner. With the Data Acquisition Toolbox providing the connectivity layer to the digital device and MATLAB serving as an environment to program the Centronics logic model, it is possible to develop an application that can take a simple string and output it to the parallel port.

An accompanied article discusses the logic model behind the Centronics protocol, using the Data Acquisition Toolbox and its new parallel port adaptor and the construction of the graphical user interface (GUI) to drive the demo application, dioprint.

• Required Products: Data Acquisition Toolbox
• MATLAB release: MATLAB 6.5 (R13)
• Other requirements: To run the demo a printer must be connected to the PC parallel port.

i wnat a help to connect parallel port using matlab R13(6.5), i dont find the needed help in matlab R12(6)

[osama qazaqi]

 i need your help in which to make a trivial file transfer through the parallel port using matlab R13(6.5)

[mohamed mohi]

i want to read the port(0) of the LPT! "378h"
but RTW "Digital Input block "allows only reading the status register "5 lines" only.
 how can i read the pins 2-9 of the parralel port and under which mode?

Hello this is mourad from algeria
thanks for dioprint functions , i were looking fro a way to control process using Matlab, and it will be more effective if there would be some functions on serial port RS232.

Dear Mr. Librodo

I have been using the Dioprint.m file and it works
just fine in a 1.6 GHz computer with Windows XP, But I
have problems using Dioprint.m in 2.2 GHz computer
(also with windows XP)... and the Parallel ports in
both computers have the same configuration.
I was wardering if you can help me with this concern..
Thanks a lot
I will be waiting for reply
