I understand the STM32 F4 has 4K of battery backed RAM. Can we store data in this area and retreive it after a power reset?
You can access it in multiple ways. The easiest would be through using the register class on our extended library.
It would be fairly trivial to build a driver for the RAM, either using the Register class from the OSH SDK, or “bare metal” in the PK.
Great 
Thanks for your help.
