I’m new to m2tklib and I’m trying to make UI using OLED display to control the movement of stepper motor with A4988 driver.
I tried to use U8NUMFN but when I enter any number and then call it the number can be printed using serial monitor but can’t be used in any other function.
The code is attached , I hope any body help me soon because it’s kind of graduation project.
