Here's what I've been doing tonight - managed to get the LPD6803 based LED strip to work nicely using FastSPI_LED v1 (v2 doesn't support this "old" strip) and then I moved some helper functions from some other code wot I wrote, with some help from the ShiftPWM library functions. I'm pleased so far, now to do some more with the effects and I will have my slave unit completed :-)
