Help with the Little Step-U and Simple_Serial.spin

ispear

Hello,

I am trying to use the Little Step-U stepper controller with the propeller. Can someone help me with initalizing and calling the simple_serial.spin object? I am having trouble getting a straight "serial output" that the controller is looking for.

Regards,

-Isaac

Isac,
I played around with a Little Step-U about 8 yrs ago.I found some code I had used then.I hope this will give you some idea.
I used Full Duplex Serial object.
I also used a level shifter as Stepper driver require 5V logic and prop is is 3.3V.

I hope it helps.I am not a any type of programmer so This is all the help I can provide.

Regards,

Siri
