Hi All:
I'm looking for an algorithm or flowchart or PIC ASM to handle ADC sampled voltages and perform AGC on them.
thanks.
 
Please give us more information.
AGC = automatic gain control.
What are you wanting to do?
 
Are you using the ADC to sample audio signals and keep them fixed to a given level?
 
basically yes Jon...but I am doing it a stepped way now. If the adc values are approaching the limit....I just change the default Vref to a larger one as I am using an enhanced midrange PIC.
