Reading Step/dir with Arduino
I am looking to read the step/dir going to each driver with an Arduino. I am aware that it is not recommended to use the step/dir test points but this would be my ideal solution.
Questions:
What is the reason for not using these test points?
If it will work are the drivers fine being triggered without a motor attached?
If it wont work can a get the remaining step/dir pins off the expansion header directly or will I need the breakout board? Glancing over the current limit of these pins and the current draw from the arduino digital pins it looks like I will. This seems a little silly though for what is a data pin...Thanks in advance!
