#90435 - Freq. or duty cycle or both ? Responding to: ???'s previous message |
Not sure if I follow your query.
If you want to generate fixed frequencies with a 50% duty cycle, then the easiest way would be to use Timer2 in the "Programable Clock out" . Read the data sheet for more details on this. The concerned equation is , Freq = (Oscillator Freq ) / ( n x (65536 - RCAP2H,RCAP2L)) where n=2 for a 6 clocker and 4 for a 12 clocker. I am not clear where did PWM enter the picture. Raghu |

| Not at all! | 01/01/70 00:00 | |
| Varying both frequency and duty cycle. | 01/01/70 00:00 | |
| possibly this way | 01/01/70 00:00 | |
