Hi everyone.

I'm currently building a battery-powered device, so it's only natural that I started exploring STOP MODE. Due to issues with the buttons in the simulator (they don't trigger the EXTI interrupt), I wanted to create a component with multiple checkboxes to indicate which STM32 blocks can be turned off and which events trigger the wake-up.
I believe this feature will be important and useful for use with various battery-powered devices.

Hi

Further to a previous reply I changed the target to a 32F030Nucleo64 and can simulate the interrupt. Which target are you using?

Regards

The update arrived now and the program works. I don't want to roll back.
The target is STM32F030F4P6.
Now, how about the STOP MODE?

Hello,

You could try calling these using a C icon.

Code: Select all

HAL_SuspendTick();
HAL_PWREx_EnterSTOP0Mode(PWR_SLEEPENTRY_WFI);

Some information on it here.
