Hi.
It’s fritzing.

Thanks for any assistance

#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>

#define SCREEN_WIDTH 128 // OLED display width, in pixels
#define SCREEN_HEIGHT 64 // OLED display height, in pixels

// Declaration for an SSD1306 display connected to I2C (SDA, SCL pins)
Adafruit_SSD1306 Display1(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, -1);
Adafruit_SSD1306 Display2(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, -1);

void setup() {
if(!Display1.begin(SSD1306_SWITCHCAPVCC, 0x3C)) {
Serial.println(F(“SSD1306 allocation failed”));
for(;;);
}
delay(10);
Display1.cp437(true);
Display1.clearDisplay();
Display1.setTextColor(WHITE,BLACK);

if(!Display2.begin(SSD1306_SWITCHCAPVCC, 0x3D)) {
Serial.println(F("SSD1306 allocation failed"));
for(;;);


}
delay(10);
Display1.cp437(true);
Display2.clearDisplay();
Display2.setTextColor(WHITE,BLACK);
}

void loop() {
// Correction: 248 is code for Degree Symbol…not 167
Display1.write(248);
// Correction: 37 is code for Percent Symbol…
Display1.write(37);
}

Hi Pascual it may not be my place to say this but this is what I think you should do.

Start a new project in IDE , delete the lines at the top that come with a new file.
Go to the project in RNT below the code is a button “raw code” click on that and the code opens in a new page. Copy and paste that into your new project.
You cannot copy code off a web page as you can get all sorts of weird errors.

Hope that helps Iain.

Actually the full error message is :

Any help would be appreciated, as i am a beginner 🙂
Thank you

That library is an Ethernet Library which I don’t think is used in that project…
