I think this belongs to this topic, so I will just go on here.
Following a simplified short version of my concern:
I have a very old stepper motor controller which makes one step movement, each time when I shorten two certain input wires (0V = logic true). If those are not shortened I messure a voltage of 13 V between those..
How can I use one of the Digital I/O ports of my NI PCI 6023e card to do a pulsed "shortening". I think the logic false (HIGH Voltage) of those Cards is 5 Volts. Will it give problems if I just hook it up to it? Or do I need to attach a resistor or something?
I need a pulserate about 100 Hz but I want to be able to change this frequency in real-time (10-100 Hz).
We have Labview 7.1 here. I would like to avoid the DAQmx and use the traditional legacy. And I already have four of the eight Digital I/Os in use.
Thanks a lot
Ok, shall I start a new thread after all or did I fail to express my problem or are you just not knowing ? Whatever it is, it would really help me, if you say it. 🙂
