Nokia 5110 DIsplay (Graphic LCD 84x48 from Nokia 3310) [SOLVED]

@YbuQc, you can’t drive the LED directly from a Photon pin as it draw too much current. You should drive the LED through a resistor to limit current or don’t connect it at all. You need to use a single library so we can go from there. I suggest the web IDE ADAFRUIT_PCD8544 library along with the ADAFRUIT_GFX library (making sure to add it to the demo app NOKIA5110.INO).

I suggest you use software SPI to begin so un-comment line 34:
Adafruit_PCD8544 display = Adafruit_PCD8544(A3, A5, D2, A2, D3);

and comment out line 43:
//Adafruit_PCD8544 display = Adafruit_PCD8544(SS, D2, D3);

The wiring should be (best guess since your picture has no pin names):

NOKIA      PHOTON
Vcc         3V3
GND         GND
A2 (SS)     CE/CS
A3 (SCK)    CLK
A5 (MOSI)   Din
D2          DC
D3          RST

The wiring is key so check your connections well. Can you provide a link to where you purchased the display? :smile:
