Why not drive the valves directly from some more electronics that avoids the mechanical jitter?


Some valves require different voltages and amps than others for one. Second, they all require more output than this board can provide.

We could barely drive the relay with the output of the board ...

I realize there will be delays in the hardware, but I would imagine they would be fairly consistent. As long as they are consistent, and we don't try to go faster than those delays, we should be ok.

For example, if it takes 8ms for a relay to respond. Our program says turn on for 10ms. After 8ms ...

We're not reading any data from the IO Warrior yet. We're just writing. I haven't seen a 3 ms time delay. When only one thread is running it can be accurate to the millisecond. I must have a OHCI host controller.

I firmly believe the problem is rooted in our program, but I don't know what to do ...

Hello everyone. Just a heads up, this will be a lengthy first post of mine. First of all, I've been working with this IO Warrior for about a month now and I've learned quite a bit about it during that time.

However, it seems that I'm running into a limitation of the board, the computer or maybe ...
