OH!  By the way!  This does not work: LEDS.addLeds<LPD8806, 6, 7, BRG>(leds, NUM_LEDS);

OH! By the way! This does not work:
LEDS.addLeds<LPD8806, 6, 7, BRG>(leds, NUM_LEDS);

But this does:
LEDS.addLeds<LPD8806, 7, 8, BRG>(leds, NUM_LEDS);

Notice the pin change.

With the string on pins 6 and 7, the strip turns white and you can barely make out some changes on it. On 7 and 8 it works fine.

I am using RC2 (dated Jun 27th on the download page).

Yes, because I haven’t fixed the issue with AVR’s and using two pins on the same port for software/bitbang’d SPI. I thought it was a chipset issue and it appears to be more likely an MCU issue - I don’t have problems with this on the teensy here.

It’s not a trivial fix to get right (without torpedoing the performance), so I haven’t gotten it done yet.

Aha. For some reason I thought RC2 fixed that. Okie, no biggie. It’s not stopping my development.
