STM32L152RBT6A, 80 byte backup register

[p_arbov]

Hello everyone,

we are using STM32L152RBT6A for our development. Our PCB has a battery and we use the RTClock, no matter of the way of work - frequent power  Off/ On.

           We kindly request some help in using „80 byte backup register“ like an energy independent memory, as we don't find any other suitable parameter in our processor

Has anyone tried using this memory?

Thank you in advance

Have you seen this example for use of the RTC Backup registers?
