I'm attempting to share RTC memory variables between ULP & Deep sleep wakeup stubs but im having trouble getting it working. Basically I want to have an easy way to link variables that I can reference in my RISC-V ULP (ESP32-S3) and then also access these in the deep sleep wakeup stubs and during th...

Tried to implement this but it seem to lock up my ulp whenever it tries to call the following. // Read RTC timer SET_PERI_REG_MASK(RTC_CNTL_TIME_UPDATE_REG, RTC_CNTL_TIME_UPDATE); rtc_timestamp_low = READ_PERI_REG(RTC_CNTL_TIME0_REG); rtc_timestamp_high = READ_PERI_REG(RTC_CNTL_TIME1_REG); Full ULP ...

Thanks so much! Ill try to implement this now and just use the interrupts and the timestamp of the RTC in the ulp!

Perfect in that case I could just read that when an interrupt happens for activity and that would be way better than polling....would you happen to know how to do that in the RSIC-V ULP? I found an assembly example here but not sure how to actually accomplish this using the RISC-V https://esp32.com/...

How would you do this in C for the RISC-V ULP?

How would you get the time in the ULP? This would be fine if I had a way to also log the timestamp and back calculate once the main processor is woken up. Ideally without running a while loop in the ULP.

I’m working on using the ESP32's ULP (Ultra-Low Power) mode for activity tracking with an accelerometer, and I’m trying to figure out the best way to implement this. Here’s what I want to achieve: Mark Activity as Active/Inactive: I need to monitor each minute. If a wake-up interrupt occurs from the...

Do you have code showing how you were able to do this with the SARA-R5? I've been trying to do it for awhile now. Thanks
