Hi Franz-Peter and everyone
The code below. The ratio needs to be check out I am sure it is incorrect. That will help. Other things like does speedDir need to be included etc. The loop etc works ok. the settings need a change or two! Once we know correct gear ratio and how to show it for speed steps etc I can experiment with output speed. Should I e using bipolar or monopolar?
Thanks for your patience.
