Make Your Own Compiler This Way

Make Your Own Compiler This Way is a hands-on, engineering-focused guide that walks readers through building a working C compiler toolchain for 8-bit microcontrollers, with primary emphasis on Microchip PIC16 (enhanced PIC16) and a dedicated section on STM8. It breaks the compiler into practical, buildable components, preprocessor, parser, assembler, and linker, and explains how each piece fits into a complete workflow that produces deployable binaries for target MCUs. The book teaches compiler construction using real tools and a real build environment, including GNU toolchains (MinGW) and the classic parsing stack Flex + Bison, making it especially valuable for embedded developers who want to understand what happens "under the hood" between C source code and microcontroller machine code. A full section extends the same concepts to STM8 compiler tools, highlighting architectural differences and how those differences shape compiler design decisions.
