Due vs PCD8544 (LCD Nokia 5110)

Official Hardware Mega Due
1

Hi,
I have good experience with this LCD and Uno. Everything works OK.
But now I ordered Due and I am not able get this LCD working. I tried several libraries on net but without success.
Thank you for help

2

you might check the voltage levels ... 3.3V versus 5.0V

3

My LCD is 3.3V capable, I think it is not problem.

4

can you post the datasheet of the LCD?

is the LCD I2C ?
or parallel?
8 or 4 data lines?

5

This tutorial work on Uno but not Due: Arduino Playground - PCD8544

6

there might be some pins different on the DUE?

7

I tried several configurations and pin mapping but without success

8

time for a multimeter and verify voltages and signals?

Can your Due drive leds on those pins?

9

Yes, all pins are OK and Led is working. It seems like the problem is caused by Due architecture different than Uno

Thank you.
This one works. But why not other?

It is the pin level different between DUE and Arduino after boot up.
please read Nokia 5110 PCD8544 + Due -> display not working - Arduino Due - Arduino Forum

YES! You are right. Now it works on all tutorials. Thank you very much.

Hello, I hope you can help me, my lcd 5110 worked perfectly with my arduino DUE, I was doing some testing and time began to fade and since then none of the sample codes work.

I tried with arduino pro mini and it works perfectly. any idea what could be happening?

I already reinstalled the Arduino IDE, the libraries and does not work. thanks in advance
