Hi, I am a bit confused on the lora STM32WL sequence protocol system, I want my device to sleep and wakeup according to the periodic values I want. I have made my own sleep function (stop 2 mode & radio sleep) with wake up triggered usin...

Sys_Standby函数用来是STM32进入待机模式,在该模式下,STM32所消耗的功率最低。 //进入待机模式voidSys_Standby(void) { SCB->SCR|=1<<2;//使能SLEEPDEEP位 (SYS->CTRL)RCC->APB1ENR|=1<<28;//使能电源时钟PWR->CSR|=1<<8;//设置WKUP用于唤醒PWR->CR|=1<<2;//清除Wake-up 标志PWR->CR|=1<<...
In this phase, the RTC alarm is used to wake up the system after the requested interval on the timer. Figure 3. Current consumption simulations using STM32CubeMX for smart timer Note: Refer to Cube examples: PWR_STANDBY, PWR_EnterStopMode, ...

必然涉及到“唤醒”机制,唤醒后执行 正常的功能代码,这个“唤醒”动作有多种,基本上有外部中断、中断事件、RTC自动唤醒等,外部中断多是IO口中断,比如按键触发,而RTC自动中断相比较“智能”一些,倒计时一定时间后,自动唤醒CPU,所以RTC自动唤醒基本上就是 为超低功耗定制 的,用起来非常方便,先看下STM32L151的RTC...

Read this application note to learn how to switch the STM32F7 running Linux to the Linux "suspend-in-RAM" mode. When in suspend, the entire STM32F7 System-On-Module consumes as little as 2mA @ 3.3V, at the same time allowing immediate wake-up from events on various I/O interfaces....
