I got my DRV8825 today. I got it working with my 12v 0.4A bipolar stepper motor. However, I don’t know the current setting of the limit current. Can someone please share to me a step by step instructions on how I would find out what the setting is? I read the Current limiting section in pololu.com/product/2133/ about 15 times but I still couldn’t understand it. I’m new to electronics. There was a mention of ref pin voltage on that link but I couldn’t find it on my DRV8825. Please let me know where to put my multimeter.
Any help would be greatly appreciated.
