I ordered a 1 meter NeoPixel Digital RGB LED Weatherproof 60 LED strip from Adafruit. I downloaded the library, dropped it in my libraries folder and loaded the strandtest program on one of my UNOs. I verified that I was calling the Adafruit_NeoPixel library correctly. I used a regulated 5V 2A bench supply. The hardware is wired correctly. The sketch compiled and uploaded correctly. The LED strip remained dark. I verified everything (correct) and tried running the sketch on a Mega 2560. The LED strip remained dark. I tried different pins, to no avail. Wiring three connections is absurdly simple, so there are NO wiring errors. I tried running the sketch in the Arduino ERW 1.0.3 and Visual Studio 11 environments. It made no difference. I scoped the output of the pin and found the voltage loaded down to 4.1VDC with pulses ringing about 200mv p/p. I would love to debug but can't do much with the assembler code.
Has anyone else tried the NeoPixel 60 LED strips and managed to get one to work? Did you have good pulses on the digital pin?
I appreciate any help I can get.
BTW, I am a BSEE with coding and hardware experience. I am fairly new to Arduinos, but I have developed and debugged several complex sketches. So I am not a n00b.
