C++ (Cpp) Compass::set_declination Examples

Example #1

File: AP_Compass_test.cpp Project: 08shwang/ardupilot

void setup() {
    hal.console->println("Compass library test");

    if (!compass.init()) {
        hal.console->println("compass initialisation failed!");
        while (1) ;
    }
    hal.console->printf("init done - %u compasses detected\n", compass.get_count());

    compass.set_and_save_offsets(0,0,0,0); // set offsets to account for surrounding interference
    compass.set_declination(ToRad(0.0f)); // set local difference between magnetic north and true north

    hal.scheduler->delay(1000);
    timer = AP_HAL::micros();
}

Example #2

File: AP_Compass_test.cpp Project: ArduPilot/ardupilot

// to be called only once on boot for initializing objects
static void setup()
{
    hal.console->printf("Compass library test\n");

    board_config.init();
    vehicle.ahrs.init();
    compass.init();
    hal.console->printf("init done - %u compasses detected\n", compass.get_count());

    // set offsets to account for surrounding interference
    compass.set_and_save_offsets(0, Vector3f(0, 0, 0));
    // set local difference between magnetic north and true north
    compass.set_declination(ToRad(0.0f));

    hal.scheduler->delay(1000);
    timer = AP_HAL::micros();
