Hello,

I couldn't find stepper motor API.

Is there any intent to include stepper drivers like simple 2 wire drivers?

 

Greetings,

Ali.

A specific stepper palette has not been added yet.  However, most are very simple control using Digital I/O.  We had a demo at NIWeek last year controlling a 2D stepper table and it was completely designed with digital outputs using the Arduino Compatible Compiler for LabVIEW.  Let us know if there is a specific driver you are referring to.

Thanks Steffan,
I use drivers like the DRV8825 and similar others all require a STEP and DIRECTION digital inputs.
It is not hard to generate those digital signals, but for acceleration and deceleration of steppers I don't think it is straightforward.

Is it possible that you share some of your codes?

Yes, the demo actually used similar drivers, the A4988.  I attached the xy table project that took commands over a serial port or read points from an SD card and commanded 2 steppers to move to a specific xy coordinate.  This code was running on an Uno.  Hope it helps.
