U8x8 Fonts -
To render the fonts, you'll need to write code that can read the font data and draw it on the screen. This typically involves:
Once you've chosen a font set, you'll need to convert it to a format that can be used by your device or application. This may involve converting the font data to a binary or hexadecimal format.
No, this isn't a typo. The "3x6" refers to the character spacing, not the tile size. The tile is still 8x8, but the visible glyph is squeezed into a 6-pixel width. This allows you to cram more text onto a single line, but it is almost unreadable for Western languages.

void setup() u8x8.begin(); u8x8.setFont(u8x8_font_8x13_1x2_n); // Set the font u8x8.clearDisplay();
void loop() u8x8.drawString(0, 0, "Hello U8x8!"); u8x8.drawString(0, 1, "Line 2"); delay(1000);
In the world of embedded systems, where memory is measured in kilobytes and processing power is a luxury, displaying text efficiently is a challenge. When you purchase a small 0.96-inch OLED display or a classic 16x2 character LCD, you are interacting with a specific type of font rendering system.
At the heart of this system lies a critical specification: u8x8 fonts.
Whether you are an Arduino hobbyist, a firmware engineer, or a retro-computing enthusiast, understanding u8x8 fonts is essential for getting text onto your screen without crashing your microcontroller. To render the fonts, you'll need to write
A common beginner mistake is using U8g2 (graphics) for everything because it "can do more." However, U8g2 requires a framebuffer. On a 128x64 display, U8g2 consumes:
U8x8, by contrast:
Verdict: If you are displaying text only — menus, debugging output, sensor readouts, terminal logs — U8x8 is always superior. If you need to draw circles, bitmaps, or graphs, you must use U8g2. void loop() u8x8
In the world of embedded systems, DIY electronics, and retro computing, screen real estate is often measured in millimeters and pixels. When working with small monochrome OLEDs, LCDs, or LED matrices, a specific format of typography reigns supreme: the U8x8 font.
U8x8 treats the screen as a grid of tiles.
