Hello,
As part of my first attempt at developing a PCB I am working with the A4988 stepper motor controller from Allegro Microsystems and there are a few things I don't understand about the chip (Datasheet Attached):
View attachment A4988-Datasheet.pdf
In the suggested usage diagram there are resistors connected to SENSE1 and SENSE2, but they are not assigned a value, how do I determine what to put there? I have the same question with the resistor on the ROSC pin.
What do these three pins do? The datasheet's description was not clear to me. My background is in mechanical engineering, so sorry if these are trivial questions.
Thanks,
