A user flash parameter library for Raspberry Pi RP2040
GitHub user Elehobica has coded a C++ code library to store user parameters at the end part of flash memory of a Raspberry Pi RP2040 microcontroller. With microcontrollers lacking EEPROM for parameters, having a small amount of Flash can be used in a similar manner. An overview:
Store user parameters at the end part of flash memory of RP2040
Allow parameter to have one type out of various primitive types
Provide default value for factory reset
Provide flash address auto calculation, otherwise allow to designate arbitary flash address
Serve direct access setter and getter linked to the parameter’s type
Also serve access setter and getter by id, which requires to select the correct type
