#157774 - Low-pass filter
Responding to: ???'s previous message
The peak will be divided by 256, so most of its effect will be lost.

You will not be able to see the difference between 256 samples that are one ADC tick higher and a single sample that is 256 ticks higher.

You also have to think about the (lack of) rounding. An 8-bit ADC sample of 255 may be truncated to zero, if all other samples are zero.
