Among the accessories available for the Raspberry Pi, the TFT touch display is quite interesting. By combining it with a dedicated enclosure, one gets a tiny all-in-one computer, well suited to monitor various sensors. We like it even more since our YoctoVisualization app now runs on Linux :-) There is only one minor issue with it: brightness control...

So we have kept our word, and this has now been implemented as well. Let's see how this works...
