Electrical Characteristics

Parameter	Symbol	Min	Typ	Max	Unit
Supply Voltage	VCC	2.8	3.3	5.0	V
Operating Current	ICC	-	10	20	mA
Sleep Current	I_sleep	-	0.06	0.1	mA
Logic High Voltage	V_IH	0.8VCC	-	VCC	V
Logic Low Voltage	V_IL	0	-	0.2VCC	V

Communication Interfaces

• SPI Interface: The SPI communication involves SCL (Serial Clock), SDA (Serial Data), RES (Reset), DC (Data/Command), and CS (Chip Select) pins.

• I2C Interface: The I2C communication involves SCL (Serial Clock) and SDA (Serial Data) pins. The default I2C address is 0x3C.

Usage Instructions

1. Initialization: Ensure proper power supply (3.3V / 5V) is provided to the module.

2. Interface Selection: Configure the display module for SPI or I2C communication as per your application needs.

3. Data Transmission: Use the appropriate protocol (SPI or I2C) to transmit data to the display. Follow the SSD1306 controller datasheet for detailed command instructions.

Example Code

c复制代码#include <Wire.h> // Include Wire library for I2C
#include <Adafruit_GFX.h> // Include Adafruit graphics library
#include <Adafruit_SSD1306.h> // Include Adafruit SSD1306 library

#define SCREEN_WIDTH 128 // OLED display width, in pixels
#define SCREEN_HEIGHT 64 // OLED display height, in pixels
#define OLED_RESET -1 // Reset pin (or -1 if sharing Arduino reset pin)
Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);

void setup() {
  Wire.begin();
  if(!display.begin(SSD1306_I2C_ADDRESS, OLED_RESET)) { 
    Serial.println(F("SSD1306 allocation failed"));
    for(;;);
  }
  display.display();
  delay(2000); // Pause for 2 seconds

  // Clear the buffer
  display.clearDisplay();

  // Display a message
  display.setTextSize(1);
  display.setTextColor(SSD1306_WHITE);
  display.setCursor(0,0);
  display.println(F("Hello, World!"));
  display.display(); 
}
void loop() {
