HI, Ytai. I tried my app with oscilloscope. The dir pin is able to work
when i connect it to a led and also tried it with oscilloscope.
The problem is there is no pulse output from the step pin after i connected
it to oscilloscope. I tried to look over the code but i can't find out
where is the problem.
