| The Adafruit_GFX library for Arduino provides a common syntax and set of graphics functions for all of our LCD and OLED displays. This allows Arduino sketches to easily be adapted between display types with minimal fuss…and any new features, performance improvements and bug fixes will immediately apply across our complete offering of color displays. | The Adafruit_GFX library for Arduino provides a common syntax and set of graphics functions for all of our LCD and OLED displays.

| After setting everything up, you can use ''print()'' or ''println()'' — //just like you do with Serial printing!// For example, to print a string, use ''print("Hello world")'' - that’s the first line of the image above. You can also use ''print()'' for numbers and variables — the second line above is the output of ''print(1234.56)'' and the third line is ''print(0xDEADBEEF, HEX)''. | After setting everything up, you can use ''print()'' or ''println()'' — //just like you do with Serial printing!// For example, to print a string, use ''print("Hello world")'' - that’s the first line of the image above.

| + | By default, long lines of text are set to automatically “wrap” back to the leftmost column. To override this behavior (so text will run off the right side of the display — useful for scrolling marquee effects), use setTextWrap(false). The normal wrapping behavior is restored with setTextWrap(true). | ||
