ok i will try later this afternoon to blink an led.

Do i need capacitors for the ceramic 4 mhz resonator? I have also used a ceramic with 2 legs resonator at 4 mhz.

In any case i will try to blink an led.

As i mentioned on my previous posts, i have tried also the code from elektor, and works. (i just dont have the right sensor DS1820 which is very old and i dont get the right results. but i have something in the screen at least.

With the code from Mr. Fratello, i dont have anything on the screen. That mean that there is something wrong, either with the hardware or software.

Thank a lot again for your help.
