Servo control?

**inh** · 11-11-2007, 05:00 AM

I think I remember being told that you guys were working on thise.. Any updates?

I'm going to need something to control two cables for my HVAC controls and would much rather do it through the brain than having a seperate serial controller..

i'll probably reveal my ignorance of the fusion brain system in it's entirety, but why can't you use a digital output to do it? All you need is a pulse between 1 and 2 ms. At least that's how i did it with my BS2. I don't think it even has to be a constant pulse unless it needs to maintain it's position against an opposing force.

Because the brain cant output that fast.

maybe you could sell a small add-on thing, based off of this: http://members.tripod.com/Sarconastic/servodriver.html

I really need servo control =/

I have not forgotten it, it's on my list.

then again, so is graduating...

Hehe just checking. I need a COM interface, and some way to play with servos to get my climate control working how i'd like =D I'll help with homework!

you sure?

this is my contribution to an undergraduate biomechanical engineering research group.

it's a collision avoidance environment for surgical spinal imaging.

and this is optional research. you can imagine what real homework is like

There is a COM interface available. See these threads for more info:

Let me know if you need more info - I've spent many hours during the last week working with this.

I'd like to add, I check once a day to see the status of this, and analog out. I'm wating, patiently.

Upon searching for a while, I found the Aircon2 by Mastero. From the sounds of it, it would do what I want, which is to control servos attached to the HVAC mechanisms to change temp and output position. The mechanical part makes perfect sense to me. I understand I need some sort of PWM output to control a servo, to do what I want and as I understand it, the FB doesn't off this natively. Also, Mastero seems to have disappeared from the board, or at least I haven't seen any recent posts. Since the FB does a bunch of other stuff I want (not relating to HVAC controls) I will probably go this way.

Has anyone figured out how to do this yet? I know H3rk was working on something similar, but he's taking it to the nth level compared to what I need.

I follow alot of what's going on, but the last time I programmed anything was when I could still program in BASIC or Assembly on my TRS-80 Color Computer 2/3's.

So, some of the software stuff is over my head.

But I have time to learn.

Thanks.
