PDP Current Log

[DrewTheRat]

Goal:

Log the current from each PDP channel to a CSV for later analysis. THe main goal would be to diagnose brownouts.

Acceptance Criteria:

• [x] Subsystem class for the PDP
• [x] Periodic method to capture current levels for each PDP channel once per second
• [x] Write current levels to a CSV file that can be retrieved later if necessary

With yesterday's (untested) changes, the log files will be in ~/logs/ directory, with log file names in pdp-MMdd_HHmmss.csv format (ex: pdp-0110_173042.csv), and the file is created every time the command's initialize is called (the idea is to have separate files for auton and teleop).

The format is

Time,TotalCurrent,Temperature,TotalEnergy,TotalPower,Voltage,Channel 0,Channel 1,Channel 2,...,Channel 15

logging with minimum 1 second in between each line.

TODO: use match number in file name when/if available along with match time when available.

I'd recommend using ss.SSS in the status line format to allow subsecond logging to capture short transients. Also, include a raw milliseconds columns to make graphing easier (unless excel can make sense of a human readable timestamp)

Don't forget to close this if its been tested and works
