Code to Read the Binary Inputs on Analog Buttons

[Kingofl337]

Does anyone have example code on how to read the binary digits from the OIs analog inputs? According to Mike only the first 4 binary digits are used to determine buttons being pressed.

For Example:

1000 0000 = Button 1
0100 0000 = Button 2
0010 0000 = BUtton 3
0001 0000 = Button 4

The trouble is the last four digits are random and fluctuate greatly
depending on what mood the chicklet is in so sometimes

1000 0000 = Button 1
or
1000 0001 = Button 1
or
1000 0010 = Button 1

The problem is we really don't want to make 4 cases for every button.
So we just want to ignore them.
