The U8x8 library, a sub-module of the popular U8g2 graphics driver, is the go-to solution for developers who need to display text on OLED or LCD screens while consuming as little memory as possible. Unlike the standard U8g2 mode which uses a memory-intensive RAM buffer, U8x8 writes directly to the display. This efficiency relies entirely on its specialized collection of "8x8" pixel fonts.
Whether you are working with an Arduino Uno, an ESP8266, or a tiny ATtiny85, understanding how to select and implement these fonts is key to a successful build. The Architecture of U8x8 Fonts The Basic Sets (ISO 8859)These are the standard
