Store Data without Soft Device

[Inspectron]

I have to store some data in the flash. Because I need to keep data when I power off and power on the device. Now I found on the SDK 11.0/peripheral a falshwrite example. Is this for application which needs to store data, but dont use softdevice?

I know for pstorage. But I'm not sure, if I can use pstorage without softdevice.

Hi,

pstorage (and the newer fstorage/FDS) does not work without a softdevice. You can use the non-volatile memory controller (NVMC) driver, or you can base your application on the flashwrite example that you mention.

Best regards,

I would recommend that you use a similar method to what is used in the flashwrite example:

• Select a free location in memory to store your data. In example, last page is selected.
• Calculate start address - addr = (uint32_t *)(pg_size * pg_num);
• Increase the address for each write

You do not have to "change pages", when you have filled one page, your address will point at the next page in flash.
