TSL2560 and TSL2561 are light-to-digital converters that transform light intensity to a digital signal output capable of a direct I2C (TSL2561) interface

    if (argc < 2) {
        printf("Provide loop count \n");
    } else {
        loopCount = atoi(argv[1]);
    }
    upm::TSL2561 sensor;

    for (int i = 0; i < loopCount; i++) {
        fprintf(stdout, "Lux = %d\n", sensor.getLux());
    }

		uint8_t	devAddr = TSL2561_Address,
		uint8_t	gain = GAIN_0X,
		uint8_t	integrationTime = INTEGRATION_TIME1_101MS
	)

Instantiates a TSL2561 object

Parameters

bus	Number of the used bus
devAddr	Address of the used I2C device
gain	Correct gain to use
integrationTime	Time to keep the shutter open

~TSL2561

(

)

GY65 object destructor; powers down TSL2561 and closes the I2C connection.
