Understanding OLEDs
Organic Light Emitting Diodes (OLEDs) are a type of display technology that is becoming increasingly popular in the electronics world. Unlike traditional LEDs, OLEDs use individual pixels that emit their own light, eliminating the need for a backlight. OLEDs can be found in a variety of sizes and shapes, and can communicate via SPI or I2C protocols.
The SSD 1331 Integrated Circuit
The OLED display used in this tutorial is a seven-pin colorful SPI device with an SSD 1331 integrated circuit. This integrated circuit is important to note, as it will determine which library is used. The pins are VCC, ground, SCL, SDA, RES, DC and CS. It is important to note that SPI devices are not always consistent in their naming, so the SDA and SCL lines may be labeled differently on other devices. SCL stands for Serial Clock Line and SDA stands for Serial Data Line, which is the MOSI pin on SPI devices. The RES pin is a reset pin, DC is the Data Command Selector pin, and CS is the Chip Select pin.
Installing Libraries
In order to use the OLED display, two libraries need to be installed. The first is the SPI library, which comes pre-installed with Arduino. The second is the Adafruit SSD 1331 library, which can be found on the Adafruit website. Once the libraries are installed, the OLED display can be connected to the Arduino board and programmed.
Programming the OLED Display
Once the OLED display is connected to the Arduino board, the display can be programmed to display text, images, and other data. To do this, the Arduino IDE must be used to write code that will control the display. This code will include commands to set the display size, write text, draw shapes, and more. Once the code is written, it can be uploaded to the Arduino board and the OLED display will be ready to use.
Installing Libraries
In order to use the OLED display, it is necessary to install the Adafruit gfx and Adafruit SSD 1331 libraries. The gfx library provides graphics for the display while the SSD 1331 library is specific to the type of display being used. If a different type of display is used, the user must ensure they search for the appropriate library. To install the libraries, the user must go to Tools, Manage Libraries and search for the name of each library. It is possible to install dependent libraries when one is installed, so any additional libraries should be installed at this time.
Components Needed
For this project, the user only needs the OLED display and seven male to female jumper wires.
Displaying Colors and Shapes
The first step is to include the three libraries and set the pins. The user must then define colors with hexadecimal digits. A useful link is provided in the description which gives the user a hexadecimal value for any color they select. Next, the user must create an object which references the physical display. The Adafruit SSD 1331 class manages the hardware interface for SSD 1331 ICS and instantiates the driver with Hardware SPI. The SPI argument is a pointer to the Arduino’s primary SPI bus and the following three are referencing the chip select, data command and reset pins.
Setup
In the setup, the user must first put the display. This is followed by setting the rotation of the display, setting the font size and finally clearing the display. The rotation of the display is important as it determines how the text and shapes will be displayed. The font size should be set to the desired size. Finally, the display should be cleared to ensure the display is blank before any shapes or text are added.
Adding Text and Shapes
Once the setup is complete, the user can begin adding text and shapes to the display. The text can be added using the text command and the shapes can be added using the draw command. The user can also add a background color to the display by using the fill command. The user can also add a border to the display by using the drawRect command.
OLED Display
Organic Light Emitting Diode (OLED) displays are a type of display that are used in a variety of applications, from small portable devices to large displays. OLED displays offer a number of advantages over traditional LCD displays, including higher contrast ratios, faster response times, and lower power consumption. OLED displays are also thinner and lighter than LCD displays, making them ideal for applications where size and weight are important.
Using an OLED Display with Arduino
Using an OLED display with an Arduino is a great way to add visual feedback to your project. OLED displays are easy to use and can be controlled using a variety of Arduino libraries. In this tutorial, we will be using the U8G2 library to control an OLED display. This library provides a number of functions for controlling the display, including functions for drawing lines, rectangles, circles, and more.
Drawing on the Display
The U8G2 library provides a number of functions for drawing on the display. The most basic function is the fill screen function, which can be used to fill the entire display with a single color. This can be used to create a background for the display, or to clear the display before drawing new content.
The library also provides functions for drawing lines, rectangles, triangles, circles, and more. These functions take parameters for the position and size of the shape, as well as the color. For example, the vline function takes parameters for the x and y axes, the height of the line, and the color.
Displaying Text
The U8G2 library also provides functions for displaying text on the display. The setCursor function can be used to set the position of the cursor, and the print function can be used to print text at the current cursor position. The library also provides functions for setting the font size and style, and for displaying text in different languages.
