Hello, I am using the TMC2209 in UART mode (Only serial, no step/dir/en pins) to drive a stepper motor.
i am trying to use the following library (https://github.com/janelia-arduino/TMC2209) to move the stepper right or left until it stals.
I have two questions :
-
there is commande to inverse the dir
stepper_driver.enableInverseMotorDirection())
but is there a way to know the direction (like the dirPin : 0 for one direction and 1 for the other) -
can we use the dirPin/stepPin at the same time as the UART mode.
Thank you
