Parameters

x1: the x-coordinate of the starting point of the line.

y1: the y-coordinate of the starting point of the line.

x2: the x-coordinate of the ending point of the line.

y2: the y-coordinate of the ending point of the line.

Example Code

The code draws a diagonal line from the top-left corner to the bottom-right corner of the chip.

void setup() {
    int width = chipWidth();   // gets the width of the chip
    int height = chipHeight(); // gets the height of the chip
    
    drawLine(0, 0, width, height); // draws a diagonal line from the top-left corner to the bottom-right corner of the chip
}

void loop() {
}

Notes and Warnings

All coordinates must be inside the chip boundaries, use the functions chipWidth() and chipHeight() to get the chip dimensions.
