Waiting for O(1)

Due to a misconfiguration the notification emails from my blog weren't reaching me, so I missed a couple of interesting comments on my earlier HL1606-related posts. The ones from Dan from over at Waiting for O(1) were particularly interesting, and he's written a SPI library for driving the HL1606 as well as other similar LED drivers such as the LPD6803 and WSC2801 - if you are looking for alternatives to the HL1606 he has some links on the googlecode page for his project. Dan is actually doing PMW fading of the strips, so he's driving them via timer-generated hardware interrupts. Dan has a lot of useful tips and observations about speed and power limitations he's run into and how he's solved them that are well worth checking out, check out his blog.
