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.

#Arduino i2c example sketch serial

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.

#Arduino i2c example sketch install

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. The first line will display “I’m Arduino” and second the “Hello world!” message.I2c OLED 128×64 arduino wiring Library and code explanation This sketch will make a connection between Arduino and I2C LCD display and then print a text on two lines. Now, you will develop a simple Hello World program. You can do directly from the Arduino IDE, select Sketch > include Library > Add.

Download the library, a zip file (you can download it from here) and extract the contents in the libraries folder of the Arduino IDE. The name of this library is Liquid Crystal I2C. To use the I2C protocol with an LCD display and Arduino, there is a special library to be downloaded and included in the code. To do this, connect the pins as follows: Arduino UNO/ZEROįrom sketches of Fritzing, you can look at the connections to be done in a simpler way: Writing the code Building the circuitīefore you write the code you have to build the circuit. While the LCD display alone is around € 2-3 (see here ). The LCM1602 it can find on the market, whether sold individually or along with the LCD display, the LCD1602 (see here ) form. A classic standard LCD display HD44780 16×2 (16 characters on 2 lines). The LCD1602 module consists of two parts. The usage voltages are standard as 5V and 3.3V. Both must be connected via pulled-up resistors. I2C is a type of serial bus developed by Philips, which uses two bidirectional lines, called SDA (Serial Data Line) and SCL (Serial Clock Line). The LCD1602 display has an integrated microchip that manages this type of communication, and then all of the input and output information are limited to only two PINs (excluding power supply). This problem has been solved thanks to the communication on the I2C bus. When they are connected to a microcontroller (such as Arduino for example), these displays require virtually many connection PINs occupying practically almost all available IO and leaving the multiprocessor few outputs for any other devices and sensors. However, these displays have a small problem. These values can be either a simple text or numerical values read by the sensors, such as temperature or pressure, or even the number of cycles that the Arduino is performing.

The integration of an LCD display greatly facilitates the interactivity of the project you are developing, allowing the user to directly read some output parameters. The LCD1602 – a I2C Liquid Crystal Displayer Finally you will see how to program it with a simple example showing how to display text on the display. In this article you will see how to mount a LCD display on your Arduino using the I2C communication. During the building of your projects for Arduino, you’ll often need to read the output data directly from a LCD display.
