I’ve a RQH100030 WAS, when testing with a multimeter, wheels straight ahead gives 2.5V, full lock to the right 4.9V and full lock to the left 0.4V which seems correct to me.
However in AOG it gives a steering angle of +175 degrees to the right and -170 degrees to the left. Adjusting the Counts per turn has little effect.
I think ino should be 5.5
EDIT: my bad, it is only machine that is ino 5.5 or UDP then ino 5.6
USB is still ino 5.0
Byt why not use last stable version 5.6.2 ?
and it is not 5.6.13: The .2 is before .13, but .2 could be seen as twenty
The 1115 just convert the analog signal to a digital one. Sends it to nano by i2c , nano then divide by a number set in the ino. But that number is controlled from AOG. Years ago you did have to set the number in the ino. And you still can if you want to.
So I believe your problem is connection from computer to nano, or somehow using wrong ino.
Because I hear you say that steer angles change in AOG (from positive to negative) when you turn wheels from right to the left
What is the steer angle, when you set counts per degree to the maximum values.
I can see 28 seems better, and 1 will definitely not be enough.
That actually means that your system work correct.
You should set counts per degree, so a real life measurement over wheel almost matches, what AOG tells you in the top steer angle barr.
Normally that would be around 40 deg to each side.
