This is a comprehensive guide to understanding and using u8x8 fonts within the U8g2 library for Arduino and embedded systems.

Advantages

1. Low memory usage: U8x8 fonts require minimal memory to store, making them suitable for resource-constrained systems.
2. Fast rendering: Bitmap fonts are quick to render, as they can be directly copied to the screen.
3. Simple implementation: U8x8 fonts are easy to implement, with a straightforward rendering process.
