Another consideration might be hardware related. I am planning to use a 74HC147 to control the Xtall, but it only covers 0-9. I am trying to have a switch control with 9 positions, but 15 and 10 will be outside the range of the IC. Does anyone know of an off-the-shelf IC that does 16-to-4 binary encoding? I have been unsuccessful in finding one.
