Is there noise on A/D when switching pins

robert_linder_2000

Hello,

I am currently using ATmega1284P controller board to control my the solar furnace.
The problem I have with that board that the analog (A/D) has noise on the pins when switching pins, so there is extra code to average out the readings.

Is there any problem like that with Esquilo?

Thanks,
Robert

I guess it depends on the source of the noise. If the noise is in the signal that the ADC is sampling, then Esquilo will need filtering just the same. If the noise is coming from the act of switching ADC inputs, then Esquilo has a different ADC architecture to the AVR and I have not seen a problem such as that on Esquilo.

Thanks for the quick response.
