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