Hello! I've got 40x4 LCD, so I conected it to my arduino, using liquid crystal library. Firstly, LCD was showing weird characters, so I changed library to liquid crystal 440, but when I compile my program I get this error:
In file included from sketch_jul12a.ino:1: C:\Users\Macu\Desktop\arduino-1.0.5-windows\arduino-1.0.5\libraries\Liquidcrystal440/LiquidCrystal440.h:95: error: conflicting return type specified for 'virtual void LiquidCrystal::write(uint8_t)' C:\Users\Macu\Desktop\arduino-1.0.5-windows\arduino-1.0.5\hardware\arduino\cores\arduino/Print.h:48: error: overriding 'virtual size_t Print::write(uint8_t)'
And now my lcd with liquid crystal shows only 2 white lines ;(
Any ideas, what I'm doing wrong? Maybe arduino needs external power source, to power up that big lcd. My lcd model is:
Btw. sorry for my bad English, I'm trying!
