Gentlemen, My comments are not focused on real time. An analogy may be helpful. In our shop we have 3 axis mills, 4 axis mills and 5 axis mills. I tell the shop to put everything on the 5 axis mills until they are full and then let the overflow (3 axis work) move to the 3 axis mills. I want

My Voltmeter computer interface is the parallelport and the pyvcp component that I loaded is my-meter. I like to ask 1. Can this voltmeter be used to measure AC voltage up to 1000VAC 2.Can it also be used to measure DC voltage on another count,   If yes. Do I need step-down instrument

I think the easiest way to do this is for a point to point network or even a network with a hub is to use raw ethernet packets. An ethernet packet has a payload of up to 1500 bytes. That should be large enough for most things we would want. On top of the payload we have around 20 bytes of

could you use 3 outputs from a parport to control the sync. motors? an enable pin, and then 2 of them on H bridges pulsing 90 degrees out of phase to run the motors? also, am i missing something big here, or would these motors run kinda like bipolar steppers, but designed to turn constant speed
