Prizm 5.1 and Ledstrip problem
« on: September 16, 2017, 04:02:43 AM »
Racking my brain over this, any help appreciated.

I have two WS2812B led strips wired up to the prizm 5.1. Prizm board fires up and everything else functions as normal but the led blade does not light at all. It does the initial, quick flash, when the board comes out of sleep mode. I've set the number of LEDs to 126 in the override config. I also have a 390ohm, 1/4w resistor on the data line, right next to the led strip. The strips are also facing the correct direction as indicated by the arrows on the strips. Pos pads are wired correct and go to the bat pos on the board. Both neg are wired right and one goes to the L1 and the other goes to the L2 pad, on the board. Data line goes to the LS pad.

Double checked all my wiring and even rewired it twice, just to make sure.

The leds will fire up if I don't change the Ledstrip setting from the default 0 setting, high powered LED. Obviously this is incorrect but they are getting power.

Is there some other setting I'm missing?

as you're using an external resistor, did you bridge the onboard LS one ?
