Whats the best way to generate a 49 Hz PWM with the ability to change the duty cycle. Is there a chip that can do that? Im currently using the Axiom 8Mhz Hc12 microprocessor. The smallest pulse i was able to generate was 120hz.    |

| Have a look here : Simple PWM Generator I ended up going for the 8038CCPD - Precision Waveform Generator which gives me a range of between 0.01 to 300KHz, but there are some great suggestions in the thread above. Good luck. Russell. |
