How save non-volatile data in Winstar WL0F000430xx... - STMicroelectronics Community

Hi,

I'm developing a SW project in a WINSTAR display (MCU STM32F750) and using the STM SW (TouchGFX Designer, STM32CubeIDE and STM32CubeProgrammer).

Until now, I design different screens and some parameters are saved and managed by means of the Model.cpp & Model.hpp.

But now I need to save some values in the non-volatile memory because I need the screen starts with specific values stored.

What I need to configure and add in the code (and where) to enable the writing and reading in non-volatile memory?

Thanks in advance for your time :)

Hello Josep,

Do you have any other non-volatile memory than the internal flash available on your board?

I would handle this in the model just like the rest of your data.

Hi mathiasmarkussen,

I don't have any other non-volatile memory.

How I can manage that non-volatile values in the model?

As I know, the model save values while the screen is switched on. How I can save a specific value and get that value in the next screen wake-up?
