Hi. I am using STM32L010C6Tx. I want my microprocessor to sleep for 10 seconds after processing. I want to use Sleep Mode. I don't have any interrupt pins. I want it to wake up after 10 seconds. How can I do? Solved! Go to Solution. Labels: Power STM32L0 Series ...
Otherwise the Systick interrupt will wake up the device within 1ms (HAL time base) */HAL_SuspendTick();/* Request to enter SLEEP mode */if(mode == LP_SLEEP) HAL_PWR_EnterSLEEPMode(PWR_MAINREGULATOR_ON, PWR_SLEEPENTRY_WFI);elseif(mode == LP_DEEP_SLEEP) HAL_PWR_EnterSLEEPMode(PWR_...

STM32的低功耗模式有三种, STOP, SLEEP, STANDBY. 其中SLEEP没啥用, 好处是一戳就醒. 最低功耗是STANDBY模式, 据说只有2ua电流, 但是每次醒来, 就相当于重启了, SRAM全重置, 另外一个坏处是需要指定一个PA0脚, 即WAKEUP脚的上升沿唤醒. 最好用的应该就是这个STOP模式, 寄存器跟SRAM都保存状态, 连IO都保持...

I set up EXTI so I get interupt on the correct pin GPIO B.6. But I cannot get it to wake up from stop1 mode. I call WFI and RTC wakes upp the
SCB->SCR |= 1<<2; //使能SLEEPDEEP位 (SYS->CTRL) PWR->CR|=1<<1; //PDDS置位 break; } } PWR->CR |= 1<<2; //清除Wake-up 标志 PWR->CSR |= 1<<8; //允许写入RTC和BKP寄存器 WFI_SET(); //执行WFI指令 } //系统软复位 ...
设置PWR_CSR的EWUP位,使能WK_UP用于将CPU从待机模式唤醒 PWR_WakeUpPinCmd();④设置SLEEPDEEP位,...
2、设置 WK_UP 引脚作为唤醒源。 代码语言:javascript 复制 PWR_WakeUpPinCmd(ENABLE);//使能唤醒管脚功能 3、设置 SLEEPDEEP 位,设置 PDDS 位,执行 WFI 指令,进入待机模式。 代码语言:javascript 复制 PWR_EnterSTANDBYMode(void); 4、最后编写 WK_UP 中断函数。
