Hi All

Looking to clock 16 stepper controllers from a UBW32.
Does anyone have any idea as to what the frequency limit
would be if I simply drive 16 outputs On / Off.?

PWM command would be handy if it was available for 16 outputs.

Regards

Do you mean servos, because you mention PWM?

I found it easier when i used MMBasic for the overall control and leave the timing critical parts, when using more then 2 servos, to other small microcontrollers connected to the i2c.
Microblocks. Build with logic.

Hi All

TZAdvantage, I meant Stepper.
By using PWM with 50 % duty cycle it is basically a good clock generator.
