hardware interfacing through c

Hello.
I have been trying to look for a c or c++ tutorial that has instructions on hardware interfacing code.
Provide a link or any other source.

hardware interfacing with c

what are you interfacing to?

hardware interfacing using c

I just want to interface a hand wired circut through the parallel port using visual c++
I would be glad to receive any general tutorial on interfacing using visual or borland c++.

hardware interfacing in c

Dear Kotis, well you can interface any device using parallel port the only thing you need to have is a NPN Transistor, just conenct the base of the transistor to the Data Pin of the parallel port and then connect a relay to the emitter of and provide a vcc to the collector, the relay will be connected to your device which will be operational when the transistor is switched on, there are 8 Data Pins thus you k connect upto 8 Bits of Devices that is at most 255 Devices and control them simultaneously...the control command syntax for c/c++ is
outport(0x378,a);
here 0x378 is the parallel ports address and 'a' is a variable depending on the value data pins of the parallel port will by high/low, thus operating the specific transistor/device,...

Best Regards

tutorial for hardware interfacing through c

Hi
Using C and C++ use the follwing two commands
InPort(adress) or inportB(addresss) to receive data from parallel port

Outport(address, data) or outportb(address, data) send data to parallel port

visual c++ for hardware interfacing

use an IC to protect your parallel port. Just search for that IC because I forgot to the name of it. It will be very risky to damage your parallel port.
