Hi,
I am using a Nucleo F429ZI. I want to use a CR2032 battery with the Vbat pin, just to keep the Nucleo's clock and back-up registers going whenever the board is disconnected from its supply power. At the moment now, I am testing a program that prints to an LCD screen every second. When I disconnect the supply power, I want my program to stop running completely. But it still continues to print to the LCD screen (only now every 30 seconds). I am wondering where I can find how to set configurations to completely stop my program when the supply power is cut. And also if there are any settings to minimize the power consumption when the Nucleo is in Vbat mode, so the battery can last longer. It is currently drawing between 18 and 48 mA when in Vbat mode, which is much higher than I want it.
