Data Logger in internal flash

[Tom]

I would like to make device that collects data from sensor. I would like to use internal flash memory. Is there any library that will help me?

Nordic's pstorage would be a good foundation for storing data. Do you mean something beyond that? (pstorage just handles the reading/writing to flash. The user code still have to manage the business logic, like when it's ok to overwrite, how to retrieve it, etc.)
