The geeekus 0.96'' OLED Display is an OLED monochrome 128×64 dot matrix display with I2C Interface, with characteristics of high brightness, self-emission, high contrast ratio, slim outline, wide viewing angle, wide temperature range, and low power consumption.
The driver chip SSD1306 communicates via I2C only. It is compatible with any 3.3v-5V microcontroller, such as the Arduino.
The OLED display doesn’t require backlight, which results in a very nice contrast in dark environments. Additionally, its pixels consume energy only when they are on, so the OLED display consumes less power when compared with other displays.
Specifications:
-Supply Voltage: 3.3V to 5V
-Number of Pixels：128 × 64
-Color Depth：blue
-Communication way: IIC
Connections for OLED to Arduino
- Vcc - 5V
- Gnd - Gnd
- SDA - A4
- SCL - A5
Sample Code
#include <SPI.h>
#include <Wire.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>
#define OLED_RESET 4
Adafruit_SSD1306 display(OLED_RESET);
void setup() {
// by default, we'll generate the high voltage from the 3.3v line internally! (neat!)
display.begin(SSD1306_SWITCHCAPVCC, 0x3C); // initialize with the I2C addr 0x3D (for the 128x64)
// init done
// Show image buffer on the display hardware.
// Since the buffer is intialized with an Adafruit splashscreen
// internally, this will display the splashscreen.
display.display();
delay(2000);
// Clear the buffer.
display.clearDisplay();
}
void loop() {
display.clearDisplay();
display.setTextSize(1);
display.setTextColor(WHITE);
display.setCursor(0,0);
display.println("Hello,world!");
display.println("Hello,keyestudio!");
display.setTextSize(2);
display.println("Hello!");
display.println("keyes!");
display.println("keyestudio");
display.display();
delay(250);
}
To control the OLED display you can use the adafruit_SSD1306.h and the adafruit_GFX.h libraries.
