Use static const or move array definitions to a .c file and keep only declarations in the .h . Part 6: Alternatives and When Not to Use a .h Font Library While arial_black_16.h is lightweight, it is not suited for all scenarios: arial black 16.h library
| Scenario | Better Alternative | |----------|--------------------| | Needing many font sizes | Use a vector font renderer (e.g., stb_truetype) | | Supporting Unicode (Chinese, Emoji) | Use a full GUI library (LVGL, u8g2) | | Anti-aliased text | Store 4-bit or 8-bit glyphs, but memory increases 4–8x | | High-performance scrolling | Use a framebuffer and blit pre-rendered text lines | // arial_black_16
