Need help decoding (C)
In the above example (links) is a "C" program to decode a KeyPad
using the Analog to Digital converter of an AVR..
Thing is (Not knowing) "C" if my life depended on it..
What are the "Answers" for the Formulas.. (To build the data table)
what is the "%" (Does that mean Integer) ??
also (u16) is confusing to me.. (Is that just a variable)
or is it a "Subroutine" label. ??
Like I say.. Can't follow "C" if my life depended on it..
Any Guidance to understanding these "Formulas"
and or loops would be great.
