Remember my weather station project;
As always I have  questions  about about the 16F877, here are the questions:
1. Can I have wireless transmission of data from the '877 if yes how can
implement that with RF signals?

2. Do I need an external oscillator or not, I figure the most favored is an
XT.

3. Since the '877 accepts analog signals do I need ADCs for the pressure,
humidity and temperature sensors or the built in ones(if there are any) will
work.

More questions later.
