Controlling a Stepper Motor Through Arduino and LabView

[peregrin5]

Hi guys,

I'm fairly new to LabView, and all these wiring diagrams are kind of boggling my brain.

I'm trying to control a stepper motor using an Arduino and LabView. I'm using this motor shield from Seeed Studios and a OSEPP Uno R3 Plus microcontroller Arduino clone.

I've installed LabView interface for Arduino, and have looked at the stepper motor examples, which I think I kind of get but I'm not sure I fully understand how the case structure works or why certain things are where they are. The examples seem to permit moving the stepper over continuous motion for specified numbers of steps.

I want the stepper to move a step, delay, move a step, etc. for the specified number of steps. I'm kind of confused with how I would accomplish this. 

Firstly, there are several time delay type blocks in the Timing palette, and I don't know which to use. Secondly the case structure has this array of parameters on the side of it, and they seem to be different for different cases, and I don't really know what they reference. Is this case structure a loop? How do I make it move a step, delay for a specified time, de-increment the total number of steps by 1, and then do it all over again until the steps remaining is false?

Hey Peregrin,

There is a forum dedicated to LabVIEW Interface for Arduino that is more appropriate for this question. Please try posting there to get the correct eyes on your questions!

hello everybody i need help on motor control... i am using sensor-less field oriented control techniques for 12v BLDC motor and 48v BLDC motor. For 48v bldc motor i made the motor run but its target speed doesn't match with speed of motor..for 12v bldc motor it is difficult to start up the motor..and iam really confused to measure the back emf constant of 12v, A2217-8T,1100kv motor...if you guys can help me.
