Common Pitfalls & Solutions

| Problem | Likely Fix | |----------------------------------|------------------------------------------| | Garbled text | Wrong font type (U8g2 font used in U8x8) – use u8x8_font_* only | | Some characters missing | Font is “restricted” (ends with _r) – switch to _f (full) | | Text too small / large | Choose a different base font or use scaled version (1x2, 2x4) | | Display flicker | You’re mixing U8g2 and U8x8 – use one mode consistently | | No Cyrillic / special characters | Pick a font with _cyrillic or _extended in name | Row 0: 0b00000000 (blank) Row 1: 0b00011000 (

Key Features

• Every character is the same size (usually 8x8 or 8x16 pixels).
• No RAM buffer required – renders directly to the display.
• Very fast – ideal for simple text interfaces, menus, or debug output.
• Supports only ASCII + extended characters (some fonts include Cyrillic, Japanese, etc.).

The "Small" Family: Why 8x8 Pixels?

You might wonder: "8x8 pixels is tiny. Why not use 8x16 or 12x16?"

• Uses 0 bytes of RAM for the buffer (writes directly to display pages)
• ~800 bytes Flash for an 8x8 font
• Extremely fast (writes characters at bus speed)
