My Tektronix 2445 failed me a while ago. Of course it is a custom IC that is pure unobtanium.

Good news is that I have a 2465 coming Tuesday. Isn't ebay great!

In the mean time, I'll check...

Well, here's what I have so far:
I'm going to throw it on a LabX1 and see what happens.

What I'm not seeing is a way to connect the 0-500 A/D reading to the 165uS rollover of the timer.

Setting one of the timers so that at max Z, it will rollover at 165uS, I can adjust that timer...

So here is the path that my mind is headed down:

Pulley Circumference 2.375"
Rev/Sec 4.21
Travel/Sec 10"
Pulse/sec 6063
Counts/bit A-D 12.126
Freq...

OK, Bert, I just got sucked into your site for the past few hours! Shame on you for distracting me! I'm suppose to be cranking out code!

That's neat stuff, I and never considered some of these...

Sorry about that, all of this made prefect sense in my head, I didn't do a very good job of explaining it to you.

The comment about Mach3 should have been clarified. The control panel will have...

More reading.... I'm thinking we are looking at this a bit differently.

For normal CNC, I can control the position accurately with Mach3 with limits and such. What the joystick is for is...

I will have to study your reply more when I have a bit more time, but for clarification, I need to give a few more details.

The intent of the analog of the joystick is to variably control the...

I had been playing with the idea of reading a PS2 mouse but that became cumbersome. When I realized that an old joystick had the pots directly available at the connector, it seemed like it was worth...

I'm coming up with about 6000 pulses per second for max travel speed (2.375" travel/rev, 360cpr encoder X 4, 10"/sec Max jog), so that is about 167uS as the quickest pulse repetition.

That helps...

Thanks for the hint Walter, After some sleep, I will study it and see what I can learn. I remember seeing that post once, but didn't study it or think to apply his solution to my problem. He's...

I have found a need to read an old PC joystick and generate some movement commands.
The joystick is the older type with a 15 pin DB (DA actually) connector. Mine makes 3) 20k to 80k pots and 4...
