Show HN: Header-only ASCII font renderer for embedded/SDL/terminal

2 Den1996 0 8/6/2025, 11:57:41 AM

I built a minimal, header-only ASCII font renderer for embedded systems and microcontrollers. It requires zero dependencies, supports monochrome and RGB565 displays, and uses an 8×8 pixel ASCII font (chars 32–126).

Useful for low-power devices, debug UIs, console demos, or any resource-constrained environments.

Single header (embedded_ascii.h)

Callback-based & buffer-based rendering

No heap allocation, <800B font footprint

Includes basic text measurement & demo mode
