mgalper Posted April 4, 2007 Report Share Posted April 4, 2007 So, after a few misshaps I manage to wire the LCD to the core. I get all sorts of weird lines, complete nonsense. I invert the cable and only get the backlight, no messages, characters, nothing.dead core after all? Quote Link to comment Share on other sites More sharing options...

Lall Posted April 4, 2007 Report Share Posted April 4, 2007 Hi,You can maybe check if the constrast voltage needed by your LCD should be negative or positive.I don't remember exactly what it does when you don't have the right one but if I remember correctly you don't see any character on the screen.Best regards,Lall Quote Link to comment Share on other sites More sharing options...
