Help with 2 steppermotors controlled by potentiometers

Projects Programming
20

Hi forummembers,

I managed to get my project working. The goal was to control 2 stepper motors separately using potentiometers.
On the display, I needed to see the speed of both motors, ranging from 0-100%.
The speed wasn't crucial. The idea was for motor 2 to spin faster than motor 1 (to stretch a synthetic thread).
In the attachment, you can find my code as well as a link to Wokwi.
All the necessary capacitors and pull-up resistors are mounted in my project. I couldn't draw them in Wokwi.
There are probably still improvements possible.
Feel free to keep me updated.
The dip switches of the tb6600 are set to S1 S2 S3 (6400) Off and S4S5S65 ON (0.5amp).
Sorry for the slow responses, but this was a side project amidst all my other work, so there wasn't much time to reply.

Maybe there are still mistakes, forgive me, it's my second project, I still need to learn some things.

Kind regards

Michel
