Got mine today!  Thanks Rob for setting this up.

 

Got it working with Rickta's version of oPossum's ASM code on a G2553, and finally on my F5172 after some finagling with the FLL and DCORSEL settings ... need to work more on figuring out the F5xxx UCS clock system though (some time with my logic analyzer verifying clock outputs is in order).  F5172 board is nicer b/c it has the 5V rail and they get nice and bright.

Mail came late this evening, but got my 4m strip! :thumbup:

 

Now I just have to decipher the code you smart guys wrote, so I can do some cool stuff myself.  I might have a go at that 1-D Pong game. :grin:

Oh wow those WS2801's look awesome, good idea for the tree... Also another crazy idea, have them strung on the eaves and change their color in direct proportion to the outside temp :grin:

 

Getting the F5172 to talk to them was easy with oPossum's ASM code, the trick seems to be giving the FLL + DCO time to settle properly, just waiting for the OFIFG flags to clear doesn't cut it... I added a 5ms delay before issuing my first write_ws2811_hs() call and then it was reliable.

 

The output at 5V is sick!  I compared a cyan (0xFF, 0x00, 0xFF) set of 4 pixels in a dark room pointed at the ceiling, LED Vcc = 3V3 vs. 5V and the difference was profound.  They just look "bright" when you look straight at them but the light intensity reflected off the ceiling was way better at 5V.

Do another one!  j/k, I missed this as well.

 

I'd like to go all out and get 50m of this stuff, but I want to test out a few meters first to make sure it's what I want.  It looks like I'll just try out a 5m lot from aliexpress for now.
