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...
Was pyaling around with low poer modes on a STM32L071KZ and I did found out that both HAL_PWR_EnterSLEEPMode() and HAL_PWR_EnterSTOPMode() use what looks like to be a wrong WFI sequence. The functions have the following code (which is not working, uC not going into Sleep/Stop ...
