Adjustable clock generator

[mattg]

Hello! I am trying to use a stepper motor driver chip (STK672-330) to drive a stepper motor. Can i use a 40X1 to generate an adjustable clock signal (0 to 50Khz)? if so, how? Thanks!

Hallo mattg, and welcome to the Forum

An adjustable signal sounds perfectly feasible, with a 40X1

Can you post a link to the driver datasheet please?

Then it will be easier for folks to offer advice.

Here you go!

These are pretty cool little devices!

thanks.

Thanks matt.

Are you familiar with the pwwmout command?

It'll provide a background "clock" from ~3900 Hz to 50 kHz

Below 3900, other methods are available.
Can you give a little more background to your project please?

You should use the PWMout command to make the signal, probably with a duty cycle of 50%.

Bear in mind that this can only be used on certain pins.

Thank you for the advice, i will look into it. I am new to microcontrollers alltogether and am just starting to play with these.
As for a project, i really dont have anything specific planned, i just want to see if i can get this to work.

OK.

Please download the Programming Editor,
then you can use the excellent manuals
and the Simulator.
