Anyone used Arduino and Linistepper controller together?

[Astroman]

Hi all,

Interested to know if anyone has used an Arduino board and been able to control the linistepper driver with it? I have the linistepper driver and stepper motors etc.. and wondered if it's possible to connect the Arduino to it for something like, simple focuser control... Looking at something to see me through until I can afford a robofocus or sharpsky controller.

I haven't connected a linistepper, but I have connected a similar bipolar driver. Step and direction on the schematic are inputs.

Andrew,

I have used the Arduino to drive a stepper driver (Big Easy Driver) for a camera tracker. It was very easy and I am sure that you will be able to modify the program with a few switches and conditional loops to use it for a motorised focusser.

Look at the following links:

Thanks Theo for the information, I will check it out in depth a little later. Had a quick skim over it and yes it looks like it should work with the linistepper, it is pretty much using the exact same principal as the big easy driver.
