About A4988 Stepper Motor Driver #883

Closed gurelsoycaner closed 1 year ago

gurelsoycaner commented 4 years ago

Hi, Just wondering when A4988 Stepper Motor Driver be available for use with .net core 3.0. as it is almost impossible using "Uln2003 motor component" to drive A4988 Stepper Motor.

Note: Not with WindowsIOT but Ubuntu Raspberry pi

Thanks in advance.

@krwq Have you used one of these motors before? I wonder what do you m ean by "almost impossible"

@joperezr I only tried to control stepper directly through H-bridge on Raspbian with different language and my experience was similar unless you rotated it very very slow. AR988 looks relatively simple to write a driver for. I think Uln2003 is conceptually similar to H-bridge so I expect experience to be similar.

I don't think I have any AR988 at the moment. @Ellerbach?

I'm travelling and not at home where I have a large base of components, so I need to check once back end of the week.

Uln2003 is a transistor array. So not really an H bridge. AR988 is made to create steper drivers up to sixteenth of step. To have something smooth to drive motors, better use a real driver. And correct, should be quite straight forward to create a driver. See https://www.pololu.com/file/download/a4988_DMOS_microstepping_driver_with_translator.pdf?file_id=0J450
