Thanks! That looks promising. Indeed these controllers look alike, I just hope the chinese have done a very thorough job imitating this chip
I'll be using the 2 spi ports of the STM32 / Maple, which is able to run spi up to 18 mhz.
I think I'm just have to going to order a strip to see how fast I can push it.
I'll post something as soon I have some results..
