EMLIB

Detailed Description

Low-level peripheral library.

EMLIB is a low-level peripheral support library that provides a unified API for all EFM32, EZR32 and EFR32 MCUs and SoCs from Silicon Laboratories.

EMLIB modules are provided for all peripherals and core features. The library implements no interrupt handlers. Static data, critical sections and module interdependencies are kept at a minimum.

Note

EMLIB functions assert on error if DEBUG_EFM is defined. See ASSERT for more information on error handling and default assertion and how to implement a custom handler.

Note

EMLIB does not implement support for radio features. Please refer to stack documentation for more information on RF support.
