37.1.1.配置PVD监控功能¶ PVD可监控VDD的电压,当它低于阈值时可产生PVD中断以让系统进行紧急处理,这个阈值可以直接使用库函数PWR_PVDLevelConfig配置成前面表38_1中说明的阈值等级。 37.1.2.WFI与WFE命令¶ 我们了解到进入各种低功耗模式时都需要调用WFI或WFE命令,它们实质上都是内核指令,在库文件core_cm3....

HAL_PWREx_EnterSTOP2Mode(PWR_STOPENTRY_WFI)函数,正常应该等到lptime的5s定时到才会唤醒,但实际情况却是几个ms就会被唤醒,然后再进stop2,如此反复.怀疑是systick唤醒,因为我在休眠前加上关闭systick,就不会有这中几ms的唤醒 gXDhn 2023-01-11 15:42:34 在...
