Spinning screen

Operations/Getting Started Getting Started
1

I thought I read in a post about aog screen spinning, but I can’t find it.
Aog v4.1.12 with button.ino
Its driving decent in the field, but no roll.
I went into roll and chose gps from autosteer, and the screen starts spinning. Choose none and it stops spinning. Using adafruit mma.

You need to restart AOG to prevent from spinning. Do you get good values from the MMA when you check with serial monitor in Arduino Compiler?

Allright… so…
Lets see about the settings:
Set it like this:

Fix from GGA
Heading from fix to fix
Heading correction → none
Roll → from autosteer

Did you set all the values from tractor dimensions like antenna height?
Did you also zero’ed it out after selecting the roll source?

Can you make a video from the screen?

6

Well I did a video but it won’t allow me to send it. All of my settings are the way you asked.
I don’t know what you mean by re zero unless it’s the roll zero.

7

Yes Roll Zero… but that won’t help either…
please upload to YouTube or some and post a link here

Yes there was something with zeroing the roll, but maybe it is also connected to the position set in AOG. Set to your place, restart AND make new field at your place in the world.

9

Okay, here’s the link
I did start a field and ab line, and it still spins.

10

I’m not sure if this helps, but you should set gps rate (hz) the same at aog and gps source.
You could also remove unnecessary nmea sentences. AOG only needs GGA and VTG.

11

Do you have a valid roll source? normally it is possible to ofset/zero the roll, after restart of aog when roll has been activated.
In sim it also spins like you show, if roll is activated without any roll source connected.

12

Roll is constantly changing with a huge amount of data. The serial string shows:

Current steerangle,setpoint,heading,roll,switchstate
As you can see the roll value keeps counting upwards. Something isn’t good with the data from your pcb. Looks like a bad connection or something.

13

I was tilting the steer box to show it was working. Was at 8 and I tilted it to 50 and back

14

I changed the frequency
Still learning on how to change the nmea

15

I have good stable roll coming out of steer box.
Was thinking about going back to 3.09 and try that.
I should have 3 or 4 weeks till I need this tractor. Have been thinking about trying the relay from led pin and going back to md13 drive to drive the danfoss, and trying to go back to 4.3.10. That would simplify things a lot.

16

Switched to v3.09 and now have roll

17

Are you also switching Arduino versions to match your AoG version?

18

Ya, I’m running coffeetrac.ino due to danfoss valve

19

I’m pretty sure people have been using the new version with the danfoss?

20

4.3.10?
If so, would someone let me know if they are using the md13s and how you have it wired. I’m determined to aog ino. Thanks

21

Larsvest, did you put the danfoss lines into the pcb ino ?

22

I did not, I don’t have a Danfoss valve or a cytron. But read here what grabik did in this thread.
.ino for PCB+MD13S+Danfoss valve

I think it is in the pid. Ino

23

Thanks. I’ve been reading that post and with your questions I thought you might have done that mod.
I have those sections printed out to study. My plan is to add danfoss pwm to pcb ino. I have never written code for arduino, but I think it’s doable, and Brian’s reply to put 50% cycle to the drive make me more confident.
If we can make it work, it would be nice to have a pcb revision that adds a relay to power the md13s.
