OLEDs need only 4 pins
Arduino VCC -> OLED Module VCC
Arduino GND -> OLED Module GND
Arduino 4 -> OLED Module SDA
Arduino 5 -> OLED Module SCK
In order for your OLED to display an image, animation, or text you need to be familiar
with the display function.
display()
display.clearDisplay() – all pixels are off
display.setTextColor(WHITE)
display.setTextColor(WHITE)
display.setTextColor(BLACK, WHITE); // 'inverted' text
FontColor,BackgroundColor
display.drawPixel(x,y, color) – plot a pixel in the x,y coordinates
display.setTextSize(n) – set the font size, range from 1 to 8
display.setCursor(x,y) – coordinates to start writing text
display.print(“message”) – print the characters at location x,y
display.println("Hello world!");
display.startscrollright(x, y);
display.stopscroll();
display.startscrollleft(x , y);
display.setTextSize(n) – set the font size, range from 1 to 8
display.setCursor(x,y) – coordinates to start writing text
display.print(“message”) – print the characters at location x,y
display.println("Hello world!");
display.startscrollright(x, y);
display.stopscroll();
display.startscrollleft(x , y);
display.startscrolldiagright(0x00, 0x07);
display.display() – call this method for the changes to make effect
There are also a number of basic shape functions worth remembering
Rectangle
display.drawRect(X, Y, Width, Height, Colour);
Round Rectangle
display.drawRoundRect(
X, Y, Width, Height,radius of round corner, Colour
);
Circle
display.drawCircle(20, 35, 20, WHITE);
//
(X, Y, radius, Colour);
Filled Circle
display.fillCircle(20, 35, 20, WHITE);
//
(X, Y, radius, Colour);
Triangle
display.drawTriangle(30, 15, 0, 60, 60, 60, WHITE);
//
(x0, y0, x1, y1, x2 , y2, colour).
//
(X0,y0) represents top vertex,
// (x1,y1) represents left vertex and (x2,y2) represents right vertex.
Filled Triangle
display.fillTriangle(30, 15, 0, 60, 60, 60, WHITE);
