Could someone please help me how to convert PWM signals to analog voltage using pic16F676 ? I'd like to take constant analog voltage output from PWM.
If they are fixed width pulses at a fixed frequency, what is changing?Are you sure it's PWM, not just fixed-width pulses at 10Hz?
The vehicle's Body Control Module send PWM with 10 Hz frequency to vehicle's fuel sender unit (which actually was a rheostat).
As I said earlier, more information needed.Old car 'electronics' used a crude electro/mechanical 'regulator' to provide a regulated voltage for the instrument panel
Current change, as a consequence of resistance change.What can change the reading on the meter?
Agreed.Current change, as a consequence of resistance change.
