It is important that designers of STM32 microcontroller applications can easily upgrade their microcontroller type as well as their firmware solution.
Additionally, since the standard peripheral library is not delivered for the most recent STM32 series, the SPL2LL-Converter migration tool is essential to the harmonization of existing applications with the range of new embedded product features and the ecosystem evolution.
The STM32 standard peripheral library (SPL) to STM32Cube low-layer API migration tool is designed to help developers to easily migrate their source code based on STM32 SPL drivers to any other STM32 series supporting STM32Cube low-layer drivers.
It ensures full migration within a given STM32 series and partial migration across STM32 series.
The migration is possible only for STM32 peripherals covered by STM32Cube LL drivers.
