Fonts | U8x8

U8x8 is a text-only rendering mode included in the U8g2 graphics library. Unlike U8g2, which uses a full memory buffer to draw individual pixels, shapes, and complex graphics, U8x8 communicates directly with the display's internal page architecture.

U8x8 fonts are "tile-based" or "fixed-size" fonts designed for the of the U8g2 library.

You are not limited to the default fonts. Using the or manual byte arrays, you can create custom U8x8 fonts: u8x8 fonts

Using U8x8 fonts in an Arduino project is straightforward. The library can be installed directly from the Arduino IDE‘s Library Manager. Once installed, the basic pattern for displaying text is simple:

If your project only consists of text menus or simple numeric readouts, the complexity of full graphics is unnecessary. Popular U8x8 Font Categories U8x8 is a text-only rendering mode included in

To achieve this efficiency, U8x8 fonts adhere to strict formatting rules that differ from the broader U8g2 library: : All glyphs are exactly

: It communicates directly with the display controller, placing characters into a fixed grid—typically 16 columns and 8 rows on a standard pixel display. Font Characteristics and Limitations You are not limited to the default fonts

If you’re building a clock or a speedometer, you need visibility from a distance.

When using large 2x2 fonts, remember that they occupy two rows and two columns. Adjust your next drawString coordinates accordingly so characters do not overwrite each other.
