Help for newbie: USB-Parallel DB25
Hi everyone!
I'm a programmer, I used to program high level graphic languages but now I’ve started a project where my app must connect to a machine via usb-db25 parallel and send data to start a motor in 2 directions, change the velocity, stop it, turn leds on and off and receive data when a sensor says that the top or bottom of the movement has been reached.
I've been searching a lot on forums but i don't have much (or any) knowledge in electronics. The machine is being built with some microcontrollers, I think, with a parallel port. I was told I just had to tell the builders which pins I would use to send/receive each signal. I have an usb-parallel adapter that windows recongnizes as "IEEE 1284" (Cable USB a Paralelo DB25 NM-C35).
I think I should send data to some port that is assigned to this adapter, or to the usb slot I connected it to. That's everything I can tell you for now. If someone helps me, it will be very appreciated!!!!!
Thank you in advance!!!
