SD card log groups and variables

[anoopk18]

Hi,

I am logging groups and variables using sd card and I have vicon setup for localization. Firstly, I would like to thank all previous discussions regarding sd logging, all those have been extremely helpful for my setup.

1. I referred to this documentation: and I wanted to clarify the difference between stateEstimate group and vicon data. In other words, I am trying to understand where the stateEstimate group variable gets data from and how it differs from vicon data.
2. based on the same documentation above, I was trying to understand the difference between stateEstimate and stabilizer groups. The description says that it stores the same data as stateEstimate.
3. how does stabilizer.thrust compare to motor.m1 - m4 groups? Does stabilizer.thrust equate to thrust from the entire crazyflie in Gs
4. Lastly, is there a timestamp attached to each of these groups and the data that is being stored? I didn't see one described in the config file.

Thanks!

2. I think there may be some overlap between logs from the stateEstimate and stabilizer groups. It's probably easiest to verify this by finding the relevant log parameters in the firmware.
