anyone have working nokia5110 lcd library for aurduino .
i have downloaded 3 libraries but they are not workinng.
How likley do you think it is that 3 published libraries do not work ?
Did you consider that you may be wiring it wrong or the display is broken ?
The Adafruit_PCD8544.h library definetly works.
Adafruit_PCD8544.h library works for me, too. Maybe you could provide more information besides "it won't work". Which Arduino are you using? Is it is a 5V Arduino? If so, do you have level shifters on 5110 pins?
