rvt 2:ae7a31a3c618 8 ButtonDecoder.
rvt 2:ae7a31a3c618 9 I was planning to make a r2R ladder network but I couldn't find any very accurate resitors here in Ecuador (no Señor, no tengo ... sigh)
rvt 2:ae7a31a3c618 10 so I bought some 5% resitors but they didn'0t work well enough. So this decoder sinply decoder the end value and this
rvt 2:ae7a31a3c618 11 it means only one button at a timn can be detected reliable.
