FlashStorage_STM32F1 library

Why do we need this FlashStorage_STM32F1 library

Features

The FlashStorage_STM32F1 library, inspired by Cristian Maglie's FlashStorage, provides a convenient way to store and retrieve user's data using emulated-EEPROM, from the non-volatile flash memory of STM32F1/F3, including non-genuine CH32F103xx, CS32F103xx, etc. boards.

The flash memory, generally used to store the firmware code, can also be used to store / retrieve more user's data and faster than from EEPROM. Thanks to the buffered data writing and reading, the flash access time is greatly reduced to increase the life of the flash.

Currently, the library supports both new STM32 core v2.0.0 and previous STM32 core v1.9.0

[Juraj]

maybe now you have the know-how to add support for STM32F1 to ArduinoOTA library's InternalStorage?

support stm32duino boards

[khoih-prog]

Thanks @Juraj

I'll definitely have a look there, spend some time to learn new knowledge and tricks as I currently haven't done anything with OTA yet. Just can't promise anything.

Regards,

[Juraj]

only the flash storage needs to be added in InternalStorage and the base classes. there are already 3 ARM platforms including SAMD21 implemented so plenty of examples.

EDIT: btw, @khoih-prog the ArduinoOTA library is now used in Blynk.Edgent examples (for non esp boards). These complex examples show WiFi provisioning and OTA sketch update with download of new binary from the Blynk Cloud. Blynk's Volodymyr recently added SAMD51 support to my ArduinoOTA library.
