How can I track the status of the onboard LED (STM32LO) and write that data to the EEPROM?

Hello everyone,

I have an STM32LO discovery board. Using it for a big project in IoT. How can i track the status of the onboard LED and write that data to the EEPROM? 

Say the led is on, saves that status and duration, then sends it as a packet to TTN.

As it is your application that drives the LED, you already have all the information, and you can therefore save it.

Thanks, i will need to read more on EEPROM.
