Hi. I'm building my reef-pi using the ML hat and his viparspectra controller to hopefully control my two 165w viparspectra lights. The lights are new and work fine out of the box. My reef-pi and ML hat are working with great an ADJ power strip, three temp sensors, and some float sensors for ATO and overflow warning. I've wired up the viparspectra controller to the Light1 connector using gnd, pin 13, and pin 14. I added the PCA9685 driver to reef-pi using address 64 and a frequency of 150 (default, I think). The lights do not come on when I set either/both channels to anything above 0. I'm also not getting any voltage on pins 13/14. I've checked all of my soldering and wiring for opens/shorts. I also tried switching to Light2 and pins 11/12, same result.
In playing around, I did notice that the light flickers briefly (less than a second) when I plugin the connector from the pi hat to the light controller, so it's getting a voltage very briefly it seems.
I've been emailing Michael Lane, about this, and he's giving great customer support, but thought I'd put this out here in case anyone else ran into this issue already as I sit here pondering why it's not working!
Here's some pics if it helps. I was playing around with the frequency and some other stuff to see if anything changed, so the pictures may not match exactly what I stated above:
