Hi, thanks for that reply, thats a nice testing technique, the weird thing is that i did steps 1-3 and they all passed than hooked up the circuit again to see if it works and "voilla", it worked. really weird, nothing different with connections or anything. The only thing is that when i type something "de" displayes and than a new line is started, the problem is that it doesnt go back to the begining of the new line, rather it just continuse. What do you mean by loosing "floating point". Im using an 8Mhz Crystal btw.
thanks for your help.
