[S.5] Log time with every pressure and acceleration reading #13

Closed nlundquist1 closed 3 months ago

Write acceleration and pressure reading data to the log file in csv format

nlundquist1 commented 4 months ago

Is this to every individual value or for every group of channel readings or? How does this get formatted into the csv?

It should be thought that each line of readings happens at the same time. That time should be logged in a column in the CSV.

Please see the MPRLS implementation for getting T+ from the RTC. (I.e. `rtc.geTPlusMS()). However, this might be too slow for the needed realtime datastream. What you can do instead is get the time of the first and last read, and then interpolate it over that buffer's samples.

We will not be logging the time with each acceleration. This due to:

  1. We have sunk multiple weeks of full work into this feature, yet we are still seeing incontinous timings. To continue with it would be with the sunk cost fallacy.
  2. We can get the time of launch from the G-switch, or other methods, and extrapolate over the entire sample, since we know the data itse is continuous (#18)
