INTERNAL RTC ALARM STM32 WAKE UP INTERRUPT 20 related questions found What is RTC wakeup? RTC_WAKEUP and ELAPSED_REALTIME_WAKEUPwill wake up the device out of sleep mode. If your PendingIntent is a broadcast PendingIntent , Android will keep the device awake long enough for onReceive() to ...
• A pulse (≥ 30.5 μs) must be applied to the WAKEUP pin (active high). When the WAKEUP pin is asserted, the voltage on the DSP_LDOO pin will start ramping up and it is monitored by the internal POR. Until the voltage reaches to the threshold level, the internal POR will hold...
When the customer used the internal RTC timer to test the wake up function, it was found that the timing time was off by 20%.The clock tree output is as follows.Thanks!0 Kudos Reply All forum topics Previous Topic Next Topic 2 Replies 05-29-2023 11:31 PM 774 Views Senlent...
I believe 1KHz internal oscillator can get you out of STOP. (From section 3.2.2 of PT60 Reference Manual: The LPO (≈1 kHz) for the real-time counter clock allows a wakeup from stop3 mode with no external components.) 0 Kudos Reply 04-04-2017 04:56 AM 1,065 Views IlConte...
