Melanie,

I am well aware that I am an amateur, and also I know that there is a lot for me to learn from professionals like you in whom I know there is a lot to give and share willingly and greatfully.

I respect and admire the knowledge you have and some others on this forum have .

So there is nothing personal here,no offense either.

Given my thoughts, I can now learn more from you.

Your technique may seem better in some respect. But in a case with 10 digits more i/o needed. Thus, a more expensive pic or an addition of an i/o extender is in need. This way, creating more expensive and also more complex design, conflicts with your idea.
