Electronics Project:Parallel Port Controller

Parallel Port Controller Using Matlab – External device controller using Matlab:

            This project has two sections. An opening GUI in SIMPLE DEVICE CONTROL MODE and a STEPPER CONTROLLER .In SIMPLE DEVICE CONTROL MODE you can control individual devices (here leds) through pins 2 to 9 parallel port. As you check any check box the corresponding LED blinks. As you uncheck it, LED stops blinking. When you push the push button ‘STEPPER CONTROLLER‘, the GUI for STEPPER CONTROLLER pops up. There are 3 data to be selected namely Stepping mode, delay (in ms), and the direction (Forward or reverse). Stepping modes are 3 types namely single step, half step and high torque stepping modes. Select the stepping mode, direction, delay and click on the START button .You will get the appropriate output.
