Writing Drone Telemetry to CSV

The DroneStatusMonitor class supports writing status information to a CSV file at defined intervals:

monitor.StartCapture("path_to_file", interval_in_milliseconds);

For example, the following will write status information to a file called "tello.csv" in the current working directory at 1 second intervals:

monitor.StartCapture("tello.csv", 1000);

To stop capture:

monitor.StopCapture();

If the file does not exist, it is created and column headers are written to it before starting to write status records. If it already exists, it's appended to and the column headers are not written to it.

The columns output to the file are as follows:

Column Order	Name	Contains
1	Date	Date and timestamp for the record
2	Sequence	Sequence number (see Monitoring Drone Telemetry, above)
3	Pitch	The pitch of the drone
4	Roll	The roll of the drone
5	Yaw	The yaw of the drone
6	Speed X	The speed of the drone along the X axis
7	Speed Y	The speed of the drone along the Y axis
8	Speed Z	The speed of the drone along the Z axis
9	Temperature Minimum	Drone temperature minimum
10	Temperature Maximum	Drone temperature maximum
11	TOF	TOF sensor distance tothe ground
12	Height	Drone height in dm
13	Battery	Battery charge as a percentage
14	Barometer	Barometric pressure
15	Time	Time of flight
16	Acceleration X	The acceleration of the drone along the X axis
17	Acceleration Y	The acceleration of the drone along the Y axis
18	Acceleration Z	The acceleration of the drone along the Z axis
19	Error	Any errors generated reading the status or an empty string if none
