I can switch the relay off while the program is on and I manually switch it, but that's not the normal behavior I presume. Should I be doing something special to get the relay to switch off before standby?

From green: Copy/paste this PM into a post in the open forum, and we'll add functionality to the program!

So, what I'm wishing to do is get the FB software to switch the amps off before I go into standby and then auto switch them on after standby. I haven't tried fiddling with HibernateTrigger yet, but that may work out. The FB unit should switch the relay off if the software is turned off? I'm not sure mine is doing that. I'll have to test some more.

I was going to wire my FB to the psu's 12v line, but opted not to since I don't know which line would die first, the 12v line to the amps (thump) or the FB (no thump)...

Thanks.

closing the software should turn off the output. what version are you using?

HyperZulu · 04-17-2008, 02:39 AM

Pretty sure I have 2.2.1 running. I'm going to run and check that I'm not a liar right now.

greenman100 · 04-17-2008, 02:47 AM

2.2.1 should turn off the outputs. are you using the timer tag?

HyperZulu · 04-17-2008, 02:54 AM

I left the defaults. TIMER is set to 30. I just checked it out, as long as the brain has power and I turn on the software, the pins switch on and don't shut off unless I press off from within the program. I just put the computer into standby and the pins are still lit.

Set the timer to 0.

You're basically setting the brain to stay on for like a day

HyperZulu · 04-17-2008, 11:06 AM

Wasn't in the manual

It was set to 30 in the tutorials section. Is there a document outlining different properties and what their values can be set to, what they mean, etc?

What should I set TIMER to in my case?... 0, 1? Not sure how this variable increments. I guess I'll experiment.

greenman100 · 04-17-2008, 01:48 PM

woops, i mean set the timer to 0. sorry

HyperZulu · 04-17-2008, 07:49 PM

Set timer on that port to 0 and I am still having the same response. I've tried older versions of the software with the same issue. Not really sure if this is hardware or software. On one hand it seems like software... but I don't know how the unit is programmed on the PIC. Is it set to look for the *.exe and if missing, turn off all ports? Or are all ports supposed to be switched off when the program shuts down? In any case, the brain leaves the port(s) on. I say ports since I tried other ports and they all behave the same way.

greenman100 · 04-17-2008, 08:14 PM

The software should shut everything down on exit, wait for 2k1's response on that.

are you sure you're actually closing the software (check task manager)

what happens when you unplug the unit, with all timers set to 0?

HyperZulu · 04-17-2008, 09:17 PM

I've checked task manager for to see if the process was still running, but there was no sign of the fcc executable. It does end when I exit the application. I've stopped the computer to make sure. I have also tried unplugging the USB cable, but it seems as long as the unit itself has power, the port stays lit. I haven't done these things with the new TIMER settings, so I'll try those things now and post back.

So far the only two things that switch the port off are toggling it off from inside the GUI or cutting power to the FB.

On a side note. I noticed that the FB doesn't need to be grounded. It looks like it can ground itself through the USB, which is kind of scary to me for some reason. I saw this when I went to cut power to the FB by severing the ground wire and it stayed on. As soon as I pulled the USB cable, it went cold. A ground is a ground is a ground?... or is this concerning?

HyperZulu · 04-17-2008, 09:34 PM

So I just tried everything and the same deal. Turn port on, set machine to restart... thump, check out the FB. Port still lit.

greenman100 · 04-17-2008, 09:36 PM

How are you powering it?

The brain has to share the ground with the computer, part of USB spec.

When did you buy your brain?

HyperZulu · 04-17-2008, 09:50 PM

I've powered it both on its own power from a fused distro block and also off the PC's psu (a DSATX). I purchased the brain on january 13th of 08.

greenman100 · 04-17-2008, 10:00 PM

that's the newest firmware, which should shut off it's outputs, as well as the software.

powering it either of those two ways, it can return through the USB cable

you're absolutely right, it's behaving that way. I'm not sure why.

nick.......?
