Happy Pongal

தைப்பொங்கல் வாழ்த்துக்கள். I really wanted to finish this before Pongal but instead I'm one day late. Anyway, I've posted my improved demo of broadsheetfb. I've reduced latency quite a lot (I haven't measured but it should be quite significant) and the more important change is host cpu utilization is now a lot lower. I've posted a video of this here and you can contrast that with the demo that I made during CELF. I've posted code for both the things that I did to improve this. The gpiolib changes need to be split to make review easier and hopefully I'll then be able to convince everyone that its a decent idea and not shortsighted. I've also just posted the damage interface code. I'm very excited about these displays and watching them improve is great fun.
