I am having trouble getting my Nokia 5510 LCD screen to work with my Arduino Uno. I have wired up 3-7 on the screen to 3-7 on the Arduino board. I had wired power (1) back light (8) and Gnd (2) to Gnd, but I burnt out the back light so now I have it set to 3.3v. I have downloaded the Adafruit libraries for this screen, but I cannot get anything to work on it. Can someone please tell me how to get this screen to show something, or how to even test if it works?
Hi,
It's hard to say what you'll need to do without knowing more about your circuit. You say you've burnt out the backlight LED how how do you now expect it to work again? Are you using a 5V tolerant board with the display on it, or a conventional 3.3V board and external level shifter (eg CD3040 or equivalent) ?
If you've let the magic smoke out of a 3.3V module you may need to get yourself another before you continue.
Cheers !
