A basic question,
how can i configurate time& date synchro for dataflash log:
i have tried this with no success:
Mavlink inspector:
GPS & mavlink usb wire connected
thanks all
GPS receiver needs to have a GPS lock before arming the vehicle.
Then the timestamp on the Dataflash logs is correct.
Without GPS also it works if the GCS sends the systemtime message but for some reason, it doesn’t work every single time though
Needs to be done before arming the vehicle. And the LOG_DISARMED parameter should be 0.
Not sure. I never practically use LOG_DISARMED = 1 for flight but still I mostly get logs timestamped correctly if connected to MissionPlanner at least
Dont stm32s have builtin rtc which drifts but can probably give the correct day?
Also, in the bitmask, what does the HW flag indicate?
edit: i saw that the lsi is inaccurate and there is also no VBAT on the board so it would reset as soon as power goes out.
It would require constant power to be operational.
No, they do not. Any RTC needs a RTC battery . I do not know of any FC that has a RTC battery.
yeah i realized that but it would draw like a very small current and for most users who probably power it once in a week, a large supercap like 5-6farad might be good? I have no idea tbh
from some calc, it should run for ~98 days theoretically (which should be atleast 30 days in practice I think) on 5f capacitor, which could be pretty useful. but, might not justify the extra weight for some users.
