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, Includes basic text measurement & demo mode
