stm32-config

Framework for reliable storing of configuration data in STM32 and MSP430 embedded flash

It supports storing of fixed size data in non-volatile storage using 2 flash sectors with atomic updates. The data is protected by CRC16 checksum. Additional measures are taken to ensure the durability of updates in the presence of power failures during flash writing and erasing.
