The DSI shield consists of two PCBs - the main board, where all the cool stuff is and a small adapter board, usually different for each display, connected through a 30 pin 2mm pinhead. The main board is a typical Arduino shield. I routed the design on 4 layers, with the signals on the 2 outer layers, a contiguous ground plane and a split power plane. The adapter boards simply route the DSI lanes, power and backlight signals to the display's connector. There's completely no standard governing DSI LCD panel connectors and power, so for each display type you'll need a separate adapter board.
The prototypes were made by Itead studio:. The intestines of the FPGA are shown below. The CPU is responsible for initialization of the display and controlling the framebuffer. It can also do some simple drawing operations although not too fast. I chose a Lattice Mico32 soft-processor due to maturity of the design and because other successful OSHW projects use it e. The CPU controls the following peripherals through a Wishbone interconnect:. The first 2 kB are reserved for the bootloader, the remaining 14 kB is the actual application.
Tells the HDMI source of the timing requirements of our display. Used pretty much as a black box here. Just as the name says, it puts together the images from HDMI and the framebuffer using simple color keying and outputs the final pixel stream for the display. Display resolution and blanking timing is programmed by the CPU through Wishbone interface. The clock lane data output is simply fixed to 0xaa, resulting in a DDR clock at the output of the SerDes.

I am working on an encoder for the former. The only DSI mode currently supported is Command Mode, Video Mode is still being worked on and is not as well documented for the target panels. This panel works in dual DSI mode, so two transmitters are used each transmitting half of each line.
A demo project is included for the afforementioned panel and config. Unfortunately a signal integrity issue on this board means I have to run the DSI link at its lowest rate, Mbps, which limits the framerate to about 30fps.
Nonetheless, the design files for this board are included if you want a circuit to run the display, although in any system you develop the MIPI DSI translator resistors should be located much closer to the FPGA to avoid the issues I've had. The final intended use of this interface is for a larger project I am working on, the openMixR 4k headset. Skip to content.

But not as amazing as building the thing in the first place.
I love your project.
I want to know more about this project so I want to know if I can ask more. I want to take this project as reference about how to implement FPGA real application interface, you should work at hardware because what you did is not easy at all. So it's really a study case. Great work! I would love to interface the same way with a mobile camera module. Do you think it's feasible? Maybe using the spartan chip can be done both with your card.
