I cant' resist!

If 13th on a Spectrum (around 1983) now maybe 40 something. But this does not have to do with the attitude. Either you have it or not.

Being polite is a way of life.

Anyway, I do respect every member of this forum, but some deserve a little extra like Melanie.

Did not got exactly all the answers? Why not re-ask? No hurt. Blaiming for un-helpful and no-one is going to help in the future. Why bother? Our time is precious besides...

1. Set up is fine.

2. You got it. But consider to use (if you don't) the Usart for most efficient way to send receive data and also interrupts (look for DT-INTS on the forum).

3. As stated a resistive voltage divider is all that is needed. Simple ohms law to find the values according to your Vin/Vout needs.
