Faithful Rust port of Maurycy's mcufont.h — a 5x5 monospace pixel font (~350 bytes of bitmap data) covering A-Z, a-z, 0-9, and the punctuation set - + . , ? ! : = '. - no_std, forbid(unsafe_code), zero deps with default features. - Public glyph tables (UPPER / LOWER / DIGITS / SYMBOLS), SYM_* index constants, and a glyph(c: char) lookup. - Each glyph row is packed in bits 7..=3 MSB-first so the bytes are byte-for-byte compatible with embedded_graphics::ImageRaw. - Optional `embedded-graphics` feature exposes MCU_FONT (MonoFont<'static>), FONT_DATA, and McuGlyphMapping for drop-in use with MonoTextStyle / Text on any DrawTarget (SSD1306 over I²C, ST7735, etc.). - Per-category feature flags (upper / lower / numbers / symbols, all on by default) so users can drop unused glyphs from flash. Licensed CC BY-NC-SA 4.0, inherited from the upstream font data. An email is out to the upstream author asking for a permissive software license (MIT / Apache-2.0); if granted, the crate will be relicensed and a new version published.
