Sorry about that

The same thing happens with
Brian and Weder (switch-button) .ino
At the moment, I can not say precisely what are the readings,
(I do not have AutoSteer PCB with myself)
but it changes depending on what I set in .INO.

When i changing values in .INO
the reading of raw values in AOG is also changing
and whatever values to set the readings are always stopped in the middle (between full left and full right) on W.A.S.
on 2V

I doubt the bad ADS1115.

Hi all,
Just want to share some advice. Don’t buy a clone Nano, always go for genuine Arduino. I had a cheap clone and yes it did work but I had lots of connection problems and had to do things in a set order. I just replaced it with a genuine Arduino and now i just switch it on and everything works! Unbelievable difference it’s great.
Thanks all just had to share this.

Alright so after a year I have dabbled in my spare time enough to build a setup.

Before I install it in a tractor is there a way for me to make the steer motor run in the program well its on my work bench to make sure it works?

I can see my wheel angle sensor input working .

Cheers,

Hello ,
After a few tries of my autosteer, I have a lot of trouble to reach good settings to follow the line. ca derive and corrects too late, or so it zigzag violently .... I have a steerpointzero very good, however, count by degree defined by steer wizard, very stable angle sensor, stable mma ... No hardware problem. But if anyone could give me a description of the method to use for PID setup and steer ... I would like to take a look at it from here, but my english is not good enough to understand everything orally. But if someone very nice could write such a description, I will have no difficulty in translating it into French. So please help me .

I've replaced the A/D converter and everything is fine now

I have a very basic 12 volt steer motor system with cutting driver.
I use look ahead 2.5 prop gain 42 output 22 min pwm 45. This works quite well at 10 to 12 kph. Might not be so good slower. Watch Brian’s utube video on pid settings. I find if prop gain is too high it weaves. I use quite high pwm because I only have 12 volts powering the steer motor. Get a rough setting then just try changing one thing at a time.
Good luck.

Thank you kuridge for your answer .

Every installation is different, mine is a phidget 24v engine with an RC wheel on a Fendt tractor. The values ​​you tell me frighten me, they seem to me too high in view of the test that I did. But maybe I'm wrong I'll try.
My request for help is not to have precise values, but rather a method to find the one that will work for me. I do not understand English well orall, I need a method or information in writing to translate correctly. I am French .

In Brian’s videos he says the two most important settings are look ahead (2-2.5) too far takes long time find line, too close weaves. And counts per degree (get a protractor and measure how much turn on front wheel and make sure that is what it says on AgOpen. Then just fine tune other settings.
Hope this helps. Kevin
