Is there a place where I can get basic trouble shooting?

Is there a place where I can get basic trouble shooting? I have an APA102 LED strip and when I connect it to the Uno, all the LEDs turn white - cool but not what I was going for with the ColorPallete sketch that came with the library.

I have checked all my connections and put this line in:
FastLED.addLeds<APA102, DATA_PIN, CLOCK_PIN, RGB>(leds, NUM_LEDS);

Any thoughts?

Thanks,

Chip

This is a good place. I’m sure there are others such as the forums at arduino.cc
Unfortunately I don’t know the apa102

Try this: FastLED.addLeds<APA102, DATA_PIN, CLOCK_PIN, RGB, DATA_RATE_MHZ(12)>(leds, NUM_LEDS);

Jason, Thank you for the suggestion, I did see that data rate can be an issue. However, this did not fix my problem. I am using the Arduino 1.6 release on a Mac - do you think there could be an incompatibility with the FestLED 3.1 library and this setup?

Are the Arduino and the LEDs sharing a common ground?

Jon, Yes, I have connected the Arduino and 5V power supply grounds. So the Arduino has three connections to the strip (ground and data and clock through 330 ohm resistors). The Power is connected with a 1000uF electrolytic capacitor. I am sure I am doing something basic wrong as I have two strips and they both act the same. Just not sure what my screw up is.

Thanks, Chip

Have you tried the Master 3.0 FASTLED library code instead of the 3.1 with the same results?

What pins on the Uno are the data and clock connected to?

Sorry for the confusion, I was using 3.0.3 not 3.1. The data pin is 12 and the clock pin is 11. Does it matter as long as I define them up front?

Might try it with Arduino 1.0.6, I think FastLED is still being tested with 1.6: https://plus.google.com/102282558639672545743/posts/5h51wXJWFbe
