actually I changed the cystal from a 4 to a 20Mhz, changed everything,
I get weird result, but I will work on it and try many things.
Also if you have a link on a tutorial that explains the different
possibilities of sending signlas , that would be appreciated, here is
what I have to deal with and I am not sure 100% on why I should choose
on over another.
