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...
超低功耗产品必然涉及到“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STM32...
WiFi module, with STM32 development board to control each hardware module; the software module is based on the Android platform development of mobile APP, and users can login through the mobile APP, connect to the server, send instructions to the lower Computer, set the wake-up time, etc. ...
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, ...

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....
Battery-buffered real-time clock (RTC), can also be used for wake-up Beeper Status LEDs for CAN channels, memory cards, and power supply Microcontroller STM32F765NIH6 (based on Arm® Cortex® M7) 32 MByte SDRAM in addition to microcontroller RAM Aluminum casing with flange 8 to 32 V...

ST25R3916 driver In the AutoDevKit, the driver used to manage all the ST25R3916 features is the same as the one developed for the STM32 ODE. The X-CUBE-NFC6 driver has been reused by changing only the low-level driver API...
