flight_recorder module

Record flight data according to your telemetry file.

Data are stored on a SD card with the pprzlog format. Currently only supported on Apogee/Fixedwing using chibios implementation. The selected telemetry file should include a FlightRecorder process.

Example for airframe file

Add to your firmware section: This example contains all possible configuration options, not all of them are mandatory!

<module name="flight_recorder">
  b'<define name="FLIGHTRECORDER_DEVICE" value="dev" />\n  '
  b'<configure name="FLIGHTRECORDER_SDLOG" value="TRUE|FALSE" />\n    '
</module>

Module configuration options

Configure Options

• name: FLIGHTRECORDER_SDLOG value: TRUE|FALSE
  Description: Enable/disable logging on internal SD card (default=TRUE)

Define Options

• name: FLIGHTRECORDER_DEVICE value: dev
  Description: Device to be used when not internal SD card (ex: uart0)

Module functions

Init Functions

These initialization functions are called once on startup.

• flight_recorder_init()

Periodic Functions

These functions are called periodically at the specified frequency from the module periodic loop.

• flight_recorder_periodic()
  • Running at maximum module frequency.
  • Autorun: TRUE
    Periodic function automatically starts after init.

Datalink Functions

Whenever the specified datalink message is received, the corresponing handler function is called.

• on message INFO_MSG_UP call flight_recorder_log_msg_up(buf)
