Hi Marshall,
Could you please double check that the wiring of the sensor is correct? What is the I2C address of your sensor?
I am using a cheap TSL2561 sensor module that I bought from ebay. After attaching it to Raspberry Pi I can see the sensor as:
pi@raspberrypi:~/rpi-examples $ i2cdetect -y 1
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- 39 -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --
After that the usage of the examples is straight-forward. The second example uses library wiringPi:
pi@raspberrypi:~/rpi-examples $ cd TSL2561/c/example
example/ example-wiringpi/
pi@raspberrypi:~/rpi-examples $ cd TSL2561/c/example
example/ example-wiringpi/
pi@raspberrypi:~/rpi-examples $ cd TSL2561/c/example/
pi@raspberrypi:~/rpi-examples/TSL2561/c/example $ make
gcc -c -o TSL2561.o TSL2561.c -I.
gcc -c -o TSL2561_test.o TSL2561_test.c -I.
gcc -o TSL2561_test TSL2561.o TSL2561_test.o -I.
pi@raspberrypi:~/rpi-examples/TSL2561/c/example $ sudo ./TSL2561_test
Test. RC: 0(Success), broadband: 80, ir: 13, lux: 8
pi@raspberrypi:~/rpi-examples/TSL2561/c/example $ cd ..
pi@raspberrypi:~/rpi-examples/TSL2561/c $ cd example-wiringpi/
pi@raspberrypi:~/rpi-examples/TSL2561/c/example-wiringpi $ make
gcc -c -o TSL2561.o TSL2561.c -I.
gcc -o TSL2561 TSL2561.o -I. -lwiringPi
pi@raspberrypi:~/rpi-examples/TSL2561/c/example-wiringpi $ sudo ./TSL2561
Lux: 10

Good morning Leon,
Well, this is a little embarrassing, but I didn't want to just leave you hanging - it turns out that the device I've been working with is actually the TCS34725, not the TSL2561 at all! When I used the appropriate code for the device - everything works as it should! Sorry for the confusion!
Just the same, my thanks to you for the code I did successfully use for the HTU21D-F, not to mention your response above. Have a great day!
Sincerely,
Marshall

Hi Marshall,
Thank you for the feedback and no worries. Btw feel free to add an example about TCS34725 to this project. I will be more than happy to review and merge a GitHub pull request with such an example :)
Best regards, Leon
