Proteus idle stepper setup

[Krakert]

Hey, everybody!

I got a Proteus V0.4 and I want to configure the stepper motor to control the idle adjustment on the throttle body.
For that, I need to configure some things, but not sure what is correct.

When I burn this configuration, I get:

Somebody here that could help me out, or can share their configuration.

Please always include a URL of your full tune while posting those amazing settings screenshots.

Of course, here are the latest settings:

Let's change these to "idle valve"? We maybe/probably need better parameter validation here. I know that some work is planned in this area under https://github.com/rusefi/rusefi/issues/3657

Overall the problem is that you are more or less the first person to try use this I am not aware of a reference configuration.

Kind of good news I need to try this _soon_ but soon could mean 4 or 12 weeks.

Ahh, oke, that's is a bit of a bummer, but good for the project, is there a way I could help out?
I'm not really familiar with the code or any, but I do understand those languages.

Here are PD11 and PD8 already configured, but I am not running an ETB, should I just set these all to NONE?

I do not know. I've asked Matt to help with https://github.com/rusefi/rusefi/issues/3661

This weekend I did some experimenting myself.

The current tune is online:
https://www.rusefi.com/online/view.php?msq=769

I have wired the stepper motor as following:

ETB1 negative: yellow tube (coil A)
ETB1 positive: yellow tube (coil A)
--------------------
ETB2 negative: Black tube (coil B)
ETB2 positive: Black tube (coil B)
See:


In the ETB menu, I remove all the pins that were assigned there.

And assigned them in the idle Valve menu:

When I upload this tune, I hear the steppers, power-up, and they do become a bit hot, after half a minute, so they are doing something.
But I don't know how to test/set-up them further.

You can move position slider in open look idle valve control. If it does not move without RPM you can enable self-stimulation of RPM, but i think it should move even with zero RPM?

The menu is saying:

But still, with the internal trigger simulation, it is not doing anything.

BTW my hard-coded tune of same is at https://github.com/rusefi/rusefi/blob/master/firmware/config/engines/gm_sbc.cpp

OMG this was all pretty broken on the UI side?!

I moved away from using the build in H-bridges, and started using a TB6600 driver.
Those drivers a cheap, and have optocoupler build in, so dont need to worry about destroying the driver.

I supply the driver with 5V of the proteus, and use 3 lowside drivers to pull down the signal.
Took me a while to get it working tho
