How to store information permanently

Question

How do I store information permanently so I can access them after a reboot or shutdown? For example, something like volume or display brightness settings.

Hello,

first of all, you need some suitable storage (non-volatile memory) in order to store the desired data e.g. a flash memory, EEPROM, SD-Card...

From your GUI project you can read the persistent data after the application has been started or when the different settings are needed. Each time the settings have changed you can store them immediately or just before shut-down.

The access to the non-volatile memory should be handled like any other communication by implementing a device interface. Let me refer to our comprehensive documentation about this topic: Integrating with the device and Implementing a Device Interface.

I hope this helps...

Best regards,

Manfred.
