Data Log Formatting - nickywongdong/wombat GitHub Wiki
The structure of the various textual data logs are described below.
obd_log.csv
From left to right:
Field | Units |
---|---|
Timestamp | Date/Time (24hr) |
Engine Load | Percent |
Engine Speed | RPM |
Vehicle Speed | KPH |
Throttle Position | Percent |
Relative Throttle Position | Percent |
Runtime Since Engine Start | Seconds |
Fuel Level | Percent |
Coolant Temp | Celsius |
Ambient Air Temp | Celsius |
Barometric Pressure | Kilopascal |
Note: Timestamp field uses the Axolotl's time/date.
ahrs_log.csv
From left to right:
Field | Units |
---|---|
Timestamp | Date/Time (24hr) |
Pitch | Degrees |
Roll | Degrees |
Yaw | Degrees |
Note: Timestamp field uses the Axolotl's time/date.
Note: AHRS orientation is based on the PCB facing right-side up and the serial port end facing towards you. Positive pitch means below horizon, negative pitch means above horizon. Similarly, positive roll means roll to the left, negative roll means roll to the right.
master_log.csv
Collated obd_log.csv and ahrs_log.csv after Axolotl has been exited. OBD connection must be successful for this log to be produced (i.e. obd_log.csv for the current boot cycle must exist).

DTCs
DTCs are displayed as code number and code meaning, listed as tuple list, one per line.
Dashcam Footage
Dashcam footage is saved in 5-minute segments in the .mp4
format. The number following front_dashcam
in the dashcam files' names indicates the segment number of that dashcam video. The date and time of the video file's creation correlates to the exact date and time of which video capture began.
