New software filter for adc reading

[aratti]

Hi Darrel here the version 2. In this version, I am using the mean instead of single data and then I select the median. Let see how it perform.

Charlie:

With a 12 bits ADC there is the possibility of overflow, with a 10 bits ADC you are ways within the word size, even if you sample 1023 which is the maximum value.

Cheers
