I've got a 2x16 LCD but although I initialize it with 2 display lines, It only shows 1 line, and I've looked it over and over again for hours now, but I can't find the problem.

connection LCD <> uC:

D0 to D7 are connected to P1
P3.5 = RS
P3.6 = R/W
P3.7 = Enable

the program shows 16 t's and let them scroll.

I've tried 3 LCD's but none of them gave text on the 2nd line.

thanks in advance,
