Hello colleagues,
I need some clarification viz :
I am using a 8051 based derivative of Philips.I need to drive two steppers simultaneously with minimal code overhead.
I am planning to use a PWM output , since I have 4 PWM outputs possible.Unfortunately they all have the same time base.
So is it possible to use a single time base and clock the 2 L297s with different duty cycles and thus generate different speeds independantly?
In other words does the L297 work only with a 50% duty or is it immaterial as long as it gets square pulses ?
Any suggestions ?
Thanks for reading
Thomas
