hello,

I know people like to filter the VACC pin on the mega128.. i know they normally put put an inductor between VCC and the AVCC pin, and also a capacitor between the AVCC pin and GND.

my question is.. what values for inductors and caps do you guys use to do this?

Thanks

The filter makes the AVCC cleaner.... how much cleaner depends on if the 5V was noisy! Just an R and a C is better than nothing! f=1/(2piRC)... make the freq as low as you can... 1Hz
