EMDRV
Detailed Description
energyAware drivers
EMDRV is a set of function specific high performance drivers for EFM32, EZR32 and EFR32 on-chip peripherals. Drivers are typically DMA based and are using all available low-energy features. For most drivers, the API offers both synchronous and asynchronous functions. The APIs are fully reentrant and callback based.
Most drivers are compile-time configurable to allow the highest possible code size optimization for the application. Compile-time configuration is defined in *_config.h files. Templates for the configuration files can be found in emdrv\<driver>\config.
- Note
-
EMDRV APIs use
Ecode_t
to return status.
With the exception of ezradiodrv, EMDRV does not implement RF support. Please refer to stack documentation for more information.
