I've followed your wirings and I can't make it work. I can't even run 1 motor.
Can you please help me? I figured it could be the GPIO numberings that is the problem but i tried using board numbering and it still doesn't work.
Also, does the location of the library (AMspi.py) you created matter for this one?
It seem that with this library the motor not run max speed? Is that the common issue when control motors using Shift Register?
Hi guys! I waste all the day for connecting it with pi zero w, but nothing. I ve tried all what I have found on rpi forum, the Last lib was your but nothing happens.
Then, I Just change pi from zero to 3b+ and it works!
Why it cant work with pi zero w?
Thank you
Upd: I tried to use sd card from 3b+ on zero, but still nothing

How to use this code for pan and tilt setup using 2 servos on a Raspberry Pi 3
could u pls me help me with the connections and what part of the code shld me removed to make it work?
I can't figure out what's wrong, because I've tried everything... pleeaasse update the script to allow use for the raspberry pi 3 model B+...
This library was my last resource on a hobby project & now I don't think I'll be able to complete this project of mine :(
Hi, i'm trying your library with a Raspberry pi 3 and it's not working. The script runs ok but nothing happends. You think it should run anyway (so it's something with my connections) or it might be a difference with the Rasp versions?
Regards,
SC
I would like to ask everybody who is using this library and did some improvement if you can send me PR. Or if there is somebody with time to help with this project.
Sadly, this project is not a priority for me due to lack of free time. And also I do not own newest Raspberry Pi 3 so I can not solve/test lot of issues.
I am open to any kind of help.
Thank you!

Hi Jan,
I'm try to using but I've a problema when I try turn on just a M3 motor. It start very slow or not start. When I turn on the four motors, everything is ok.
I'm using raspberry pi 4 model B
Other issue, when I turn on the raspberry and motordrive together some motors start work unexpected
coding working:
amspi.run_dc_motors([amspi.DC_Motor_1, amspi.DC_Motor_2, amspi.DC_Motor_3, amspi.DC_Motor_4])
time.sleep(3)
amspi.stop_dc_motors([amspi.DC_Motor_1, amspi.DC_Motor_2, amspi.DC_Motor_3, amspi.DC_Motor_4])
Not working propely :
amspi.run_dc_motors([amspi.DC_Motor_3])
time.sleep(3)
amspi.stop_dc_motors([amspi.DC_Motor_3])
The image with the wiring diagram seems t obe missing. Can you upload another version?
