Below is an example demonstrating the functions used for drawing graphics on the Inkplate 6:

ℹ️

The color parameter in these functions depends on the display mode. In black-and-white mode, use BLACK or WHITE. In grayscale mode, use values from 0 to 7. Refer to the display modes page for more details.

#include "Inkplate.h"
Inkplate inkplate(INKPLATE_3BIT);
void setup() {
    inkplate.begin();
    inkplate.clearDisplay();
    inkplate.display();
    // Draw a pixel
    inkplate.drawPixel(100, 50, 0);
    // Draw a line
    inkplate.drawLine(0, 0, 1023, 757, 1);
    // Draw a rectangle
    inkplate.drawRect(100, 100, 200, 200, 2);
    // Draw a filled rectangle
    inkplate.fillRect(300, 100, 200, 300, 3);
    // Draw a circle
    inkplate.drawCircle(512, 100, 75, 4);
    // Draw a filled circle
    inkplate.fillCircle(512, 100, 75, 5);
    // Draw a rounded rectangle
    inkplate.drawRoundRect(310, 300, 400, 300, 10, 4);
    // Draw a filled rounded rectangle
    inkplate.fillRoundRect(310, 300, 400, 300, 10, 3);
    // Draw a triangle
    inkplate.drawTriangle(300, 500, 700, 500, 512, 200, 2);
    // Draw a filled triangle
    inkplate.fillTriangle(350, 467, 650, 467, 512, 250, 1);
    // Update the display to render the drawings
    inkplate.display();
}
void loop() {
}
