Product overview
Description
The X-CUBE-RC-CALIB Expansion Package describes how to measure and calibrate internal oscillators. It also describes which internal features are used for calibration or measurement.
Each oscillator trimming functionality is implemented in a separate file, so that users can easily select the file they need, without using the whole software package.
The X-CUBE-RC-CALIB Expansion Package is built on top of the STM32Cube HAL drivers.
