Software Signal to Hardware Signal

Hi, paramsivan4u. Can you provide the forum with some more information? For example, what are the details of the software and hardware configuration that you plan to use?

hi,already m\c screen has the display output,.i want to take the output as a harware output like open and close by converting the software to digital output.

Generally speaking, the idea is to get the software to toggle a pin on the processor chip - that's your hardware signal. Most processors have i/o pins that can be controlled by s/w.

thank you for your information.

It depends on what platform you are working. If that is microcontroller programming it requires to know the i/o ports provided and the corresponding address.

If it is on a PC the parallel port is the best solution. Its address is 378H. so a code like

out 378H 8 ;

will turn on the 4th bit ON (because 4=00001000 in binary)

Good work
