oops! ok! thank you!!
how can I help??
@DanielCuartas, the port is done and the IDE library updated. Let me know how it works! 
Couldnāt get it to work,
Exact same error as before 
Maybe is not updated in the build platform yetā¦
@DanielCuartas, you may need to ādetachā the existing library and re-attach the new one which is version 1.1.0. Are you using the GFX or mfGFX version of the library? I havenāt yet updated the mfGFX version.
@peekay123 I just used Particle Dev and everything went smooth!!! Perfect!!! Awesome!!! Youāre the best!! Thank you for the fast response!!

Hello,
Iāve the exact same LCD as @rlacerda83 and I canāt get it to work. I tried several libraries : Nokia5110 and Adafruit_PCD8544. The screen doesnāt display anything.
I first suspected a faulty screen but when I tried it with my Arduino Nano, it worked like a charm, on first try.
I tried several pins configuration (hw and sw SPI), but stil nothing.
I have the latest v0.7 firmware, and Iām using the 3.3V from the photon to power the screen. I checked the voltage and itās at 3,3V.
I configured it with the same setup as @DanielCuartas, but still no luck 
So if anyone manage to get it work, or is willing to help me, please let me know.
@YbuQc can you list your wiring or post a good picture of your setup? I believe @DanielCuartas was powering the display from Vin, not 3V3.
So here is my setup
LCD Photon
VCC +3.3V
GND GND
SCE A4
RST D3
D/C D2
DIN_MOS A5
SCLK A3
LED : NC or +3.3V
And in the code, I declared the following:
Adafruit_PCD8544 g_Display = Adafruit_PCD8544(A3, A5, A4, D3, D2);
Then I try a simple:
g_Display.begin(); // This will setup our pins, and initialize the LCD
g_Display.display(); // with displayMap untouched, SFE logo
I donāt have any compilation error and the firmware upload works fine.
I also checked the LCD power voltage. Without LED connected I have +3.3V, with LED connected I have +2.9V. This LCD is supposed to work within the range +2.7;+3.3.
But you are right @peekay123, on the picture, the LCD is powered through Vin. I just checked and Vin on my Photon is +4.7, which is too much for my LCD.
@YbuQc, which library are you using?
I tried with the following libs:
- Adafruit_PCD854 with Adafruit_GFX
- Nokia-5110-LCD
Not at the same time of course 
And also, Iām using th WEB IDE.
In my loop() function, I add the following lines, which is from the demo code:
g_Display.clearDisplay();
delay(1000);
g_Display.setTextSize(1);
g_Display.setTextColor(BLACK);
g_Display.setCursor(0,0);
g_Display.println("Hello, world!");
g_Display.setTextColor(WHITE, BLACK); // 'inverted' text
g_Display.println(3.141592);
g_Display.setTextSize(2);
g_Display.setTextColor(BLACK);
g_Display.print("0x"); g_Display.println(0xDEADBEEF, HEX);
g_Display.display();
delay(2000);@YbuQc, I noticed that the D7 LED is on in your picture. Is this expected? Also, are you certain your system firmware and your app are at the same version?
@peekay123, yes the D7 LED is on, and itās done on purpose. Iām building with IDE set to use firmware is 0.4.7. Just checked with the
Serial.printlnf("System version: %s", System.version().c_str());
And the answer is
System version: 0.4.7
I tried with the example from the Adafruit_PCD854, just changed the pin for the init with my setup:
Adafruit_PCD8544 display = Adafruit_PCD8544(A4, D2, D3);
Still no luck. The serial terminal displays the value from the function testdrawbitmap() but nothing happens on the LCD.
Also re-tried the Nokia-5110-LCD lib, same result.
I switched bread-board (opposite side) just in case, but no luck.
Well, I must admit Iām quite confused 
Edit: I noticed that the setContrast method didnāt do anything when I connect A0 to LED LCD pin, even if I set the contrast value to 200.
Edit 2: With th Nokia-5110-LCD and the following setting :
Nokia5110LCD::Display nokiaLCD(D2, D3, D4, blPin, A5, A3);
I can see a very quick and brief display update once. Seems to be a partial logoā¦ ā¦ even more confused!
@YbuQc, you canāt 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 donāt 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? 
@peekay123, I bought my LCD here. As itās using the PCD8544 I assumed it was ok
I will try this evening the software SPI with the exact same wiring as you suggested, using the Adafruit librairies.
Oups, I forgot indeed to specify the LCD wiring. Here we go, from left to right (on the previous picture)
Row LCD
20 VCC
21 GND
22 SCE
23 RST
24 D/C
25 DIN_MOS
26 SCLK
27 LED
@YbuQc, the display is a Nokia5110 and should work. Looking at your wiring, I am confused with āRowā numbers. What do these represent? Your wiring should be:
PHOTON NOKIA
VCC 3V3
GND GND
A2 (SS) SCE
A3 (SCK) CLK
A5 (MOSI) DIN/MOSI
D2 D/C
D3 RST
LED NO connection!!
My previous wiring list was a backwards! For now, donāt connect anything to the LED pin of the display. Give this a shot
@peekay123, the ārowā was the row on the breadboard
So, just compiled the example with Adafruit_PCD8544 (and the GFX). Wiring setup as required.
I can see a quick āglitchā during the logo display, but after that nothing :ā(
I checked all the connections (continuity with the multimeter), between the pins on the Photon and the pins on the LCD.
The voltage VCC/GND is at +3.3V
@YbuQc, are you running the demo app that comes with the library?
@peekay123, yes Iām running the demo app. Nothing changed, only add a
while(!Serial.available()) Particle.process();
to wait for the āenterā on the keyboard to continue the program. But I tried first without and doesnāt make any difference.
@YbuQc, I would say that you either have a wiring, power supply or defective display issue. Are you powering the LED input of the display and if so, how?
