As you've probably noticed, there hasn't been too many activity on the DSI Shield project during the past year. Many people were asking me where to buy the boards, how to set them up for a particular display and so on.
Unfortunately, the amount of my spare time does not allow me to contribute to the DSI Shield enough to make it a viable product - that is manufacturing and shipping the boards, providing user support or adding new features. It's just too much for a single person doing this sort of stuff in free time (most of which is already devoted to KiCad development).
If someone of you is interested in manufacturing these boards or firmware development, let me know.
