I am looking for a way to read digital inputs in my software that is running on a PC.
For an application I use an incremental encoder (line drive RS422) to count the speed of a conveyor belt.
Now I connect the encoder to an Arduino Uno that is reading the digital output of the encoder and "translate" it to a serial signal, so that I can read it with my PC/software.
This works, but is not a solution I like. I prefer to read the digital inputs directly on my PC and translate it there to a readable signal for my software, without using an external micro controller.
Does NI have PCI cards or other solutions that are able to do this?
I hope some can help me with this.
