This article explores the u8x8 font system, explains how to use them, and highlights the best fonts for your next project. 1. What are U8x8 Fonts?

// Define the rendering function void render_font_char(uint8_t char_code, uint8_t x, uint8_t y) // Load the font data for the character uint8_t *font_ptr = &font_data[char_code * 8];

Though packed into an 8x8 container, the actual glyphs are tiny. This allows you to space characters manually or embed micro-indicators. u8x8 fonts

To use these fonts, initialize the U8x8 version of your display driver instead of the standard U8g2 driver.

#include #include // Initialize the display using hardware I2C // (Replace with your specific screen driver if not using SSD1306) U8X8_SSD1306_128X64_NONAME_HW_I2C u8x8(/* reset=*/ U8X8_PIN_NONE); void setup() // Start the display hardware u8x8.begin(); // Power save off allows the screen to light up u8x8.setPowerSave(0); void loop() // 1. Select your U8x8 font u8x8.setFont(u8x8_font_chroma48_f); // 2. Print simple text at Column 0, Row 0 u8x8.drawString(0, 0, "SYSTEM READY"); // 3. Switch font for a different style or icon set u8x8.setFont(u8x8_font_amstrad_cpc_e_r); u8x8.drawString(0, 2, "Temp: 23.5 C"); // 4. Demonstrate inverted (reverse video) text u8x8.setInverseFont(1); // Turn on invert mode u8x8.drawString(0, 5, " WARNING! "); u8x8.setInverseFont(0); // Turn off invert mode to restore normal text delay(5000); Use code with caution. Advanced U8x8 Font Techniques Displaying Icons via Text

When you install the U8g2 library, you get access to dozens of u8x8 fonts. Here are the critical ones:

Below is an example sketch for an I2C SSD1306 OLED display (128x64 pixels, which creates a grid of 16x8 tiles):
