display.setRotation(0); // Set orientation. Goes from 0, 1, 2 or 3

display.setTextWrap(false); // By default, long lines of text are set to automatically ΓÇ£wrapΓÇ¥ back to the leftmost column.

// To override this behavior (so text will run off the right side of the display - useful for

// with setTextWrap(true).

}

// Convert Variable1 into a string, so we can change the text alignment to the right:

// It can be also used to add or remove decimal numbers.

char string[10]; // Create a character array of 10 characters

// Convert float to a string:

dtostrf(Variable1, 3, 0, string); // (<variable>,<amount of digits we are going to use>,<amount of decimal digits>,<string name>)

display.clearDisplay(); // Clear the display so we can refresh

display.setFont(&FreeMono9pt7b); // Set a custom font

display.setTextSize(0); // Set text size. We are using a custom font so you should always use the text size of 0

// Print text:

display.setCursor(0, 10); // (x,y)

display.println("Hello"); // Text or value to print

// Draw triangle:

display.drawTriangle(40,40, 50,20, 60,40, WHITE); // Draw triangle. X, Y coordinates for three corner points defining the triangle, followed by a color

// Draw filled triangle:

display.fillTriangle(0,63, 15,45, 30,63, WHITE); // Draw filled triangle. X, Y coordinates for three corner points defining the triangle, followed by a color

// Draw line:

display.drawLine(40, 63, 70, 63, WHITE); // Draw line (x0,y0,x1,y1,color)

// Draw circle:

display.drawCircle(47, 36, 20, WHITE); // Draw circle (x,y,radius,color). X and Y are the coordinates for the center point

// Draw a filled circle:

display.fillCircle(12, 27, 10, WHITE); // Draw filled circle (x,y,radius,color). X and Y are the coordinates for the center point

// Draw rounded rectangle and fill:

display.fillRoundRect(58, 0, 18, 18, 5, WHITE); // Draw filled rounded rectangle (x,y,width,height,color)

// It draws from the location to down-right

// Draw rectangle:

display.drawRect(79, 0, 49, 27, WHITE); // Draw rectangle (x,y,width,height,color)

// It draws from the location to down-right

display.setFont(&FreeMonoBold12pt7b); // Set a custom font

// Print variable with left alignment:

display.setCursor(83, 20); // (x,y)

display.println(Variable1); // Text or value to print

// Draw rounded rectangle:

display.drawRoundRect(79, 37, 49, 27, 8, WHITE); // Draw rounded rectangle (x,y,width,height,radius,color)

// It draws from the location to down-right

// Print variable with right alignment:

display.setCursor(83, 57); // (x,y)

display.println(string); // Text or value to print

display.display(); // Print everything we set previously

} // End of loop
