以 C 扩展 MicroPython ¶
This chapter describes options for implementing additional functionality in C, but from code written outside of the main MicroPython repository. The first approach is useful for building your own custom firmware with some project-specific additional modules or functions that can be accessed from Python. The second approach is for building modules that can be loaded at runtime.
请参阅 library section for more information on building core modules that live in the main MicroPython repository.
