- µVision Microcontroller Development Kit (MDK-ARM) toolchain V5.39
- CubeIDE toolchain V1.19.0
Supported Devices and boards
Backward compatibility
Backward compatibility with previous releases is maintained as far as compile switch UTIL_LPM_LEGACY_ENABLED is defined to 1 in utilities_conf.h
/* Enables LPM legacy APIs */
#define UTIL_LPM_LEGACY_ENABLED (1)Dependencies
Main Changes
- Number of low power profiles is flexible and defined by user in interface file
(not limited anymore to sleep, stop and standby) - Unique API to request mode instead of one per mode
