I'm quite new to the world on Arduino and i'm testing a lcd 16x2 now .. I tried but get strange thing, i'm using the liquidlibrary and the helloworld example. When i upload it i get full of Sharp then full of 3 then full of C then full of S I verified 20 times the wiring and it' ok.. (4bit wiring) the LCD is a LM093LN and compatible with HD44780 he have 2 ICs :HDD44780a00 and HD44100H.
Tried aother example or the 4bitlibrary but none is working .. Is my LCD dead ? Thanks in advance. Nico
