LCD dead ?
Jinx email (remove spam text)
If I get an LCD without a manual (and I try not to) the first
thing to do is trace the connector back to the 44780. On
more than one occassion this has saved me doing fatal
damage to the LCD. The data pins can be inverted, RS
EN and R/W get swapped around and some mongrel even
made one with the power lines opposite to standard. You
can get the 44780 data sheet here
