I also added (finally) a 100 nF decoupling capacitor to the right of the #1 LED, which should help eliminate glitches in the future. I bumped the VCC and ground tracks up in size, redid the VCC routing, and just generally cleaned things up to be nicer. Which led me to think a new real of LEDs was bad and waste a couple of days trying to track down what was going on. I could break the pad by hand and get them to work, which through trying to be quick led me creating a circuit that would work for all the colors except white because I didn’t break the trace completely. Well, two of the LEDs worked sometimes, but the third would not.Ĭlever me, I did some led moving and I managed to route the VCC line for LED #2 right across the data out pad when I did some moving. The boards showed up quickly, and didn’t work. I did a rev 1.2 of the board and sent them off to allpcb for a small run (10 IIRC, so 120 of the LED boards and 15 of the end boards). It’s been very long since my last update, and a fair bit has happened.
