Basic Infos

I'm getting a Exception (3) when i try write text to the Nokia 5110 screen. This screen worked for me a good few months ago when I was on an older version of Arduino IDE (I'm now on 1.8.2) and Esp8266 core.

Does not appear to be a hardware issue as drawing shapes works fine, crash only happens when writing text. I've tried several different sample sketches and they all crash when writing text.

Any ideas how to troubleshoot any further?

More info: The above is on OSX

I loaded up an old windows install on another computer and that worked fine:

Arduino 1.81
Core Version 2.3.0 (According to platform.txt - Installed from Github)

What's at line 165 of bitcoin.ino? The example link you have posted doesn't have line 165...
Suggest posting a minimal example so that others can reproduce the issue you are having.

Sorry about that, here are lines 164 and 165, the first time display.println is used

  display.println("  Powered by");
  display.println("   CoinDesk");

I went to try do a simple example and I'm pretty confused to whats going on! I'm getting the same error (3), but the stack refers to libraries I am not using in the example (ArduinoJson for example). I'm sure it's the right sketch as the serial monitor shows the appropriate messages (EDIT: comment below this contains a decoded stack that looks more applicaple)

Code:

#include <Arduino.h>

#include <SPI.h>
#include <Adafruit_GFX.h>
// Make sure to install the esp8266 version linked to in the first post
#include <Adafruit_PCD8544.h>

// Pins
const int8_t RST_PIN = D4;
const int8_t CE_PIN = D8;
const int8_t DC_PIN = D6;

Adafruit_PCD8544 display = Adafruit_PCD8544(DC_PIN, CE_PIN, RST_PIN);

void setup() {
  Serial.begin(9600);
  Serial.println("\n\nWeMos D1 Mini + Nokia 5110 PCD8544 84x48 Monochrome LCD\nUsing Adafruit_PCD8544 and Adafruit_GFX libraries\n");

  display.begin();
  display.setContrast(60);  // Adjust for your display
  Serial.println("Show Adafruit logo bitmap");

  // Show the Adafruit logo, which is preloaded into the buffer by their library
  // display.clearDisplay();
  delay(2000);

  display.clearDisplay();
  display.setTextSize(1);
  display.setTextColor(BLACK);
  display.setCursor(0,0);
  display.println("Hello, world!");
  display.display();
  Serial.println("You should now see Hello, world! on the display");
}

void loop() {
}

Serial output:

Looks similar to #3140 (comment). This was fixed in #3325 yesterday. Can you try again using the latest git version?
