This is just a quick one.
I am using a stimulation device which is operated through the parallel port. In order to program the intensity of the stimulation, I need to set the control pin to "high" for 0.5ms or less, and then set it back to "low". This tells the device that I'm about to send it intensity data.
However it doesn't seem possible to send sub-millisecond pulses through the parallel port using Inquisit 4. Can anybody confirm this?
