STM32F103CB ‘Sleepy mode’ and ‘Wake up’ function
[Status]
1. MCU: STM32F103CB
2. CORE1: https://github.com/rogerclarkmelbourne/Arduino_STM32
3. CORE2: https://github.com/stm32duino/Arduino_Core_STM32
hello.
We want to configure it with low power.
1. Enter ‘Sleepy Mode’ through firmware.
2. In terms of hardware, the ‘3.3V’ or ‘GND’ signal enables the ‘Wake up’ function.
3. The firmware re-enters ‘Sleepy mode’ after a certain period of time.
Are there any examples or libraries? help me.

STM32F103CB ‘Sleepy mode’ and ‘Wake up’ function
library is here

you need to use stm core for that
low power is not for novices, to do low power, the simplest way is to consult the reference manual and figure out how to do that from there.
in some low power modes, you need to trigger a reset after wake up from low power.
the simplest way to reduce power is to use
when your code is not doing anything. you can put that in loop(), and that is good as delay(1)
for a properly designed app, stm32 can run for days on reusable AA or Lipo batteries without special low power modes.
and you can re-charge and use again.
normally, things like your leds etc can take more power than a stm32

#include "STM32LowPower.h"
Can I use the above library? 'STM32LowPower' ?

@ag123
Thank you for answer.
How to use the 'STM32LowPower' library?
CORE2: https://github.com/stm32duino/Arduino_Core_STM32
Is it possible to implement it through ‘CORE’ above?

Re: STM32F103CB ‘Sleepy mode’ and ‘Wake up’ function
that is designed for Arduino_Core_STM32
I've not used it prior, hence you would need to review the examples, codes yourself.
beyond the library, review the reference manual for your soc
