#define OLED_RESET 4 // Reset pin # (or -1 if sharing Arduino reset pin)Īdafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET) OLED I2C Display Arduino/NodeMCU Tutorial: The very first program you write when you start learning anew programming language is: 'Hello World'.The program itself does nothing more than printing a. Declaration for an SSD1306 display connected to I2C (SDA, SCL pins) #define SCREEN_HEIGHT 64 // OLED display height, in pixels #define SCREEN_WIDTH 128 // OLED display width, in pixels This is example of how you draw a rectangle in this OLED display #include Drawing shapes code examples in OLED display
Draw a Triangle drawTriangle(x1, y1, x2, y2, x3, 圓, color) fillTriangle(x1, y1, x2, y2, x3, 圓, color) Įvery x,y is the coordinates of each points of triangle. X,y indicate the center coordinates of circle and you should specify the size by radius. display.fillRect (x, y, width, height, color) Draw a Circle display.drawCircle(x, y, radius, color) display.fillCircle(x, y, radius, color) And if you want your rectangle to be filled use fillRect instead. X, y indicate the rectangle position and you can specify the width and height. Draw a Rectangle display.drawRect(x, y, width, height, color) X1, y1 is the start point and x2,y2 is the end of line point. X, y is indicate the position of pixel Draw a line display.drawLine(x1, y1, x2, y2, color)

If(!display.begin(SSD1306_SWITCHCAPVCC, 0x3C)) How to Draw shapes in arduino OLED display Draw a pixel display.drawPixel(x, y, color) SSD1306_SWITCHCAPVCC = generate display voltage from 3.3V internally The address that we got from i2c scanner. Serial.println(F("SSD1306 allocation failed")) Ĭhange the default address 0x3D to 0x3C.

While (!Serial) // Leonardo: wait for serial monitor Devices with higher bit address might not be seen properly. This sketch tests the standard 7-bit addresses Added waiting for the Leonardo serial communication. As version 4, but address scans now to 127. according to the i2c scanner by Nick Gammon Scanning addresses changed from 0.127 to 1.119, Adapted to be as simple as possible by user Krodal Version 2, Juni 2012, Using Arduino 1.0.1 This program (or code that looks like it) If you don’t have one, you can copy the sketch below. To do this you can use the i2c scanner sketch.

You need two library of adafruitĪfter download the libraries, install them and restart the arduino IDE.īefore we start using this OLED display, we need to know the address of this device. But in this tutorial, I will use the adafruit library. There are some library available you can download. To run the I2C scan on a different bus, change this line of code: Download File. I2c OLED 128×64 arduino wiring Library and code explanation The example sketch above uses the default Wire bus.
