Self-Hosting Mini C Compiler for ESP32 The xcc700 is a very small, lightweight C compiler designed specifically for the ESP32 microcontroller. It is like a mini version of GCC or clang, but this system has some limitations. Instead of generating Windows .exe files, it produces ELF binaries for the Xtensa CPU, which is the processor architecture used in ESP32. Because it is so small, the compiler itself can run on the ESP32 and… |
