hummm

some more testing led me to find that disconnecting the usual ground/Power capacitor can help the whole thing to work?!
Also switched to a new regulator but this haven't changed anything.

I couln't get back to have correct display yet. only garbage and ghosts...

I ran a quick test with regular LCDOUT prg and this do work ok. Even the Lines were accesibles in correct order.
I suspect USART sync problems, which I couldn't resolve in other projects :/
How come it is supposed to be the performant solution and 10times more buggy than the software Serin??

And now this thing wants to play PacMan with me!!
All the ghost appeared by themself!
