ok yeah it was the GPIO mode.

In the end the new library is to rought and not precisely enought, even with time.sleep().

Now i got a new question. Is it possible to modify the old library to let me use release.

sorry for so much trouble and posts

by adafruit_support_carter on Tue Jul 30, 2019 12:19 pm

The old library repo is there if you want to fork and modify the code:
https://github.com/adafruit/Adafruit-Mo ... on-Library

In the end the new library is to rought and not precisely enought, even with time.sleep().

Can you elaborate on this. Is the motor not turning smoothly? Did you try tweaking the value of the delay?

Thanks i will look at it tomorrow and hopefully i can get where i want to :D

i have a little switch which is pushed once in a revolution of a rotating table. Just the command kit.stepper.onestep() is enough that this switch wont be registered when pushed. Even if i place the same or lower speed on the motor it wont be registered. But in the old library it is fin and get registered. Additonaly i dont get any issues with stuttering stepper motors at higher speed then used with the new library.

Hope my english is good enough to understand everything.

But when i use release i got an Attribute error.
With Adafruit_MotorHAT.RELEASE the stepper is giving a high frequenz sound after work is done.
With both function i do not get any of what i wanted.

Do you see any mistakes i may have build here

i have a little switch which is pushed once in a revolution of a rotating table. Just the command kit.stepper.onestep() is enough that this switch wont be registered when pushed.

Can you post a photo of this hardware. It's not clear what is happening and if this is step resolution issue or step speed issue. Or something else.

by Skydromer on Mon Aug 05, 2019 2:30 pm

Adafruit_support_carter for your efforts but i will focus on rewriting parts of the old library.

But do you know anything about my newest issues?

Can you restate what the newest issues are?

This it is. By adding those section the stepper motor is howl or python is responding with not attribute found in this class.

by adafruit_support_carter on Thu Aug 08, 2019 11:05 am

It may be how you are calling it? What line of code is giving you the attribute error?

In general, it would be best to move to the newer driver which is the one we are going to be supporting.

by Skydromer on Thu Aug 08, 2019 2:21 pm

the attribute error is coming from

def release(self):

I know but somehow the new does fit as well as the old does.

by adafruit_support_carter on Thu Aug 08, 2019 3:09 pm

I don't see how the function def could lead to the attribute error. In general, you can take and modify the old code as much as you want, but support is limited.

The new library is the one we are currently maintaining. If it doesn't work, you can open issues and we can work them.

That is what i dont understand ^^'.
Or did i added the wrong file somehow or need to change every file?

by adafruit_support_carter on Fri Aug 09, 2019 12:05 pm

In general, you should grab all the files for the old library.

by Skydromer on Wed Aug 14, 2019 1:30 am

I think i i got the problem. I use 2 different kinds of Stepper motor. One got 4 and ther other 6 wire. Just the one with 6 wire is noise with the release. Any idear why this might be. Otherwise i have to investigate more.
