Topic: Stepper motor control and button handling with bluetooth app
Hello everybody,
This is my first time in this forum and was not sure if I chose correct category.
I have issue with button handling by using RemoteXY.Handler With this simple code provided below I want to rotate shaft of stepper motor by definied number of steps, in example 200 steps. I created simple app with to buttons: forward and backward (I wanted to use desired arrows but it did not work). With microstepping 1/16 it should rotate shaft by 1/16 of full revolution. I my case however, after tapping the button (forward or backward) in bluetooth app, it rotates by 400 steps, doubled. I would appreciate for hints why motor is rotating more than required. The execution of accurate number of steps is required by some marco slider.
