This Arduino library provides a way for logging a flight in the format of an IGC file to a Stream (typically on an SD card).
For more information on the igc file format, some good resources are:
- Aerofiles igc writer
- Igc file spec from xp-soaring
The A-Record to identify the device requires a manufacturer ID, a logger ID (to tell the difference if there are multiple devices from the same manufacturer), and an Optional Id Extension string to identify either the device or the flight.
Unless your device is tested or registered with GFAC, the manufacturer ID should start with an 'X'.
Manufacturer_id: XSI ... for (S)cottyob/(I)gc-Logger
logger_id: Igc
id_extension: LoggerLib

AXSIIgcLoggerLib
Before you can start logging position updates, "I" records, or, any additional attributes to a location update must also be defined.
the logIRecords method does this. If you want to log the GPS Fix Accuracy (FXA) to be between bytes 36 and 40 (just after the manditory fields), and Satellites In Use (SIU), you'd call the following
// Add I records to extend our fixes with "FXA" and
// "ISU" records (GPS Fix Accuracy, and Satellites In Use)
const IRecordExtension extensions[] = {IRecordExtension(3, "FXA"), IRecordExtension(2, "SIU")};
logger.writeIRecord(sizeof(extensions) / sizeof(extensions[0]), extensions);
Comments can be logged and useful for however you want to display or parse them.
A popular mobile tool uses formats such as:
LXNA::PHASE:onGround
To do such a comment as this, you simply need to:
logger.writeLRecord("::PHASE:onGround");IgcLogger logger(Serial);
// Write the header the header
strcpy(logger.date, "012025");
logger.pilot = "Some Pilot";
logger.glider_type = "Awesome Glider 19";
logger.firmware_version = "1.0.0";
logger.hardware_version = "Some Variometer";
logger.logger_type = "Igc-Logger based Vario";
logger.gps_type = "uBlox 7";
logger.pressure_type = "MS5611";
logger.time_zone = "-8";
logger.writeHeader();
// Add I records to extend our fixes with "FXA" and
// "ISU" records (GPS Fix Accuracy, and Satellites In Use)
const IRecordExtension extensions[] = {IRecordExtension(3, "FXA"), IRecordExtension(2, "SIU")};
logger.writeIRecord(sizeof(extensions) / sizeof(extensions[0]), extensions);
// Write some B records

GNotImplemented
This library is currently pretty minimal. Currently, these record types are supported:
A - FR manufacturer and identification
B - Fix
G - Security
H - File header
I - List of extension data included at end of each fix B record
L - Logbook/comments
C - Task/declaration
D - Differential GPS
E - Event
F - Constellation
J - List of data included in each extension (K) Record
K - Extension data
