Hi all,

long time no see, because i'm o the business trip and really didnt have a time to meet you.

I have a question.

First of all i havent open a new thread because it is already one here.

Now let me explain you what i would like to do.

I have the following parts in my lab and would like to do some experiments. Simple not very difficult in the begining.

1) Big Easy Driver
2) Stepper Motor with Cable

Then to control the easy driver i have a pic16f88. I hope that is enough or do i need a bigger microcontroller with 4 different ports?

I understand that i need to connect from the controller to the Big Easy Driver 3 pins.

The GND, the STEP, and the DIR.

My question is: The step has to be a PWM signal? The direction pin is only high or low?

It is would be nice if anyone has a similar questions and will discuss several options.

i just want to give to the stepper motor a simple directions and basic step rotation....not microstep. I know that i can do with the Big easy driver, but i would like to start from the very basics.

thanks a lot for any help in advance.

regards,
