Almost any standard pinout 44780 will work. The pinout on the far right of **broken link removed** is standard. The only optional part would be the BL (backlight pins), and even they seem to be fairly standardized.Today I received and assembled my unicorn LCD experimenter, and was wondering what LCD does it use and what controller, because when I plugged in my Hitatchi 44780 LCD it did not even power up. Thanks
Set RB3 high to turn it on. Look on the schematic and you'll see there's a 2N2222 controlling the ground line.The backlight is software controlled
