Adafruit 16-Channel 12-bit PWM/Servo Driver reversing things?

[ianm1981]

Hi I think Ive done something silly to my PWM controller. I had it working fine on my raspberry pi controlling an RGB led strip quite happily using a mosfet to up the output levels to something capable of driving a 10m led strip. then I started playing with the java drivers for it, i think Ive set the wrong address to the wrong setting or something as it seems to be now doing the opposite of what I tell it. so when back using the adafruit library that came with it setting the 3 channels im using to on

Code: Select all

setPWM(12,0,4095)

seems to almost turn the channel off now whereas

Code: Select all

setPWM(12,0,0)

seems to put it on
I dont know quite what Ive done or if there is a simple way to factory reset this thing or if its fubard now i suspect I've changed it from one mode to another but Ive no idea how do fix it.

Any help please ;o)

ok panic over seems that while pulling power from it wasnt enough to reset it shorting the VCC, OE and GND pins all together did the trick.
