Feb 14, 2020 · In this tutorial we are going to learn how to draw rectangles on a SSD1306 OLED, using the ESP32 and the Arduino core. We are going to use this library to interact with the display using higher level methods that will make our program very simple.

Jul 29, 2012 · To create a solid rectangle with a contrasting outline, use fillRect () first, then drawRect () over it. Likewise, for circles, you can draw and fill. Each function accepts an X, Y pair for the center point, a radius in pixels, and a color: void fillCircle(uint16_t x0, uint16_t y0, uint16_t r, uint16_t color);

Feb 28, 2018 · On the OLED display, I can display the values and small bar graphs using 'display.drawRect' command to draw the box. The problem is with the 'display.fillRect' command, in that I can only get it to fill the rectangles from the top, down.

You can draw and overlap custom shapes on OLED screens to provide your users with a better User Experience. display.drawLine(StartX, StartY, EndX, EndY, WHITE); display.drawRect(StartX, StartY, Width in Pixels, Height in Pixels, WHITE); display.drawCircle(CenterX, CenterY, Radius in Pixels, WHITE); display.drawTriangle(FirstX , FirstY, SecondX ...

In this comprehensive user guide, we will learn to interface SSD1306 OLED with Arduino. We will discuss how to display simple texts, set pixels, draw lines and shapes on OLED display with Arduino. Additionally, we will also display monochrome bitmap images on the OLED screen.

Apr 23, 2023 · The drawRect(x, y, width, height, color) provides an easy way to draw a rectangle. The (x, y) coordinates indicate the top left corner of the rectangle. Then, you need to specify the width, height and color: display.drawRect(10, 10, 50, 30, WHITE); You can use the fillRect(x, y, width, height, color) to draw a filled rectangle

I found that there are a lot of different displays which can be interfaced with Arduino, but my favourite one is the OLED display. I have been using these displays since three weeks ago through the Adafruit_SSD1306 library. With this library you can do a lot of things like draw geometric shapes, display text, etc.

Sep 1, 2022 · display.drawRect(): To draw a rectangle on display. This function draws a hollow rectangle with a 1-pixel border.

Draw a rectangle (border only) or filled rectangle. You specify (x, y) of the upper-left and then the width and height. // PROTOTYPE void drawRoundRect(int16_t x0, int16_t y0, int16_t w, int16_t h, int16_t radius, uint16_t color); void fillRoundRect(int16_t x0, int16_t y0, int16_t w, int16_t h, int16_t radius, uint16_t color);

Feb 3, 2021 · learn how to draw circle, rectangle, triangle on OLED display using Arduino, ESP32, ESP 8266 as shown in the below output images display.drawLine(x0, y0, x1, y1, color); //draw a line display.drawCircle(x0, y0, radius, color); //draws circle
