Does anyone know how to produce dynamic PWM (according to realtime values being read) using MC68HC05 series micro controllers without using Timer Interrupts ?

- I am already using timer interrupts for other purpose (and tht is high priority task) and I dont have any timing constrain (still got lots of cycles free to use)

task is like..

-read value from sensor
-count % of OnDuty cycle and Off Duty cycle
-generate output on TCMP PIN (PIN 35) (DIPackage)

Thanks

 

Check if your controller has a hardware PWM. If it doesn't you should look into getting one that does. With a hardware PWM you just load the timer values for the PWM and the hardware generates the signal without any software intervention.
