Question from AVR keypad tutorial. I wanna join keypad and lcd in my project with your lcd and keypad drivers from tutorial. The problem is how to display pushed key on LCD display. I study your project and found statements like this:

while(!(key = getkey()));
key = translate (key);
lcddata(key);

I understand all this statemnt, but not working in my project. LCD display different characters. Can you tell me, what I'm doing wrong.

regards
