B4R Question [SOLVED] 64 x 48 OLED Display

[Computersmith64]

EDIT: Solved - it turned out that the ssd.InitializeI2C(4, 0x3c) was the problem. For the 64 x 48 display, it needs to be ssd.InitializeI2C(0, 0x3c).

Hi All,

I have a 64 x 48 OLED display shield that I've been trying to get working using the various examples in the forum, however have had no luck.

In the end I ran the I2C scanner in the Arduino IDE (that Erel suggested in another thread) & confirmed that the display was correctly connected to my Wemos D1 R2, however I still couldn't get the bouncy ball (or other) demos to work.

Finally I downloaded the code below & compiled & uploaded it in the Arduino IDE & it worked. So my question is, what is the B4R equivalent to this? I suspect that the "magic ingredient" is the Adafruit SSD1306 library, but I'm not sure...

#include "SPI.h"
#include "Wire.h"
#include "Adafruit_GFX.h"
#include "Adafruit_SSD1306.h"

#define OLED_RESET 0  // GPIO0
Adafruit_SSD1306 display(OLED_RESET);

void setup()   {
  Serial.begin(9600);

  display.begin(SSD1306_SWITCHCAPVCC, 0x3C);
  // init done

  display.display();
  delay(2000);

  // Clear the buffer.
  display.clearDisplay();

  // text display tests
  display.setTextSize(2);
  display.setTextColor(WHITE);
  display.setCursor(0,10);
  display.println("Hello");
  display.println("World");
 
  display.display();
  delay(10000);
  display.clearDisplay();
}


void loop() {

}
