Storage of text values in Flash

[ptillisch]

Hi @farmer_giles. Some examples of how to use the Mbed OS "KVStore" API in Arduino sketches are provided here:

Persistent storage

And as its only a few variables, probably kvstore will work. Is there an example somewhere? //https://os.mbed.com/docs/mbed-os/v6.12/apis/kvstore.html //KVStore. TDBStore - Default implementation of the KVStore API. It provides static wear-leveling and quick access for when you have a small number of KV pairs. //https://os.mbed.com/docs/mbed-os/v6.12/apis/data-architecture.html #include "KVStore.h" #include "kvstore_global_api.h" void setup() { Serial.begin(115200); while (!Serial); …

Arduino Nano RP2040 Connect Flash memory

Hi @madredman. Although the Nano RP2040 Connect board doesn't have integrated EEPROM memory, it does have flash. Unlike the classic AVR chips which have internal flash memory, the flash is provided by a dedicated IC on the board. This might be the reason why you found information that it doesn't have flash memory (since that is correct if we are speaking of the RP2040 microcontroller alone rather than the Nano RP2040 Connect board as a whole). The "Arduino Mbed OS Nano Boards" platform of t…

Even though those discussions were about other boards, they are equally applicable to the Portenta H7 since the KVStore API is available when using any of these Arduino boards that have an Mbed OS-based core.
