Does anyone know which CPU/controller has a built-in MIPI DSI interface for connecting a small TFT?
I know that the Broadcom CPUs used on the Raspberry Pi have DSI, but there is still no driver available after all these years...
It should be able to run a Linux system as I would like to build a small clock like mini computer with BT and WLAN...
The other option is to hook my round TFT to a FPGA which connects to a small Intel Edison module.
You can find RGB to MIPI DSI chips fairly cheap.
Hmm..i.MX6 is a little overkill with its graphic capabilities for a small 320x320 round TFT display (o;
STM32F4 series looks nice...as I already have a board running a Linux distro....
Another option would be to use a Cyclone V SoC FPGA, as their hard wired core has a really good performance...and DSI interface could be integrated in same chip as well....
First I need to do a small PCB for interfacing the small 0.4mm Mezzanine connector of the display to my Cyclone V SoC board and start experimenting with the timing and the capacitive touch controller...
hey davorin,
I'm quite interested in your implementation of the MIPI DSI.
Over at mike's electronic stuff, you can find a reverse engineering
effort succes of an ipod LCD.
That uses the same MIPI-DSI interface, and can come in handy.
You can also take a look here. There is code posted on his github as well.

ST also has new STM32F7 series MCUs, these are Cortex M7, should run 200MHz, has MIPI.

Which particular device? Is it going to be CSI and DSI?
Isn't the manual available on ST pages? (I don't know, I have access to internal stuff :-) )
I can't tell now, bcs I don't know. I haven't toyed much with F7 yet, last time I toy with L4 mostly.
And I think that the new F469 should also have the MIPI and the DS and RM should be available on the web.
//EDIT: Saidly, no manuals available for public, only NDA. But it is MIPI DSI. Both F479 and F746. (these two should share the same peripherals).
Does this mean the STM32F7 manuals will never be publicly available because it contains a display interface normally used for mobile devices?
Ofcourse not, sorry if it wasn't clear. But with our company policy it's quite not sure "when or where". I tried to ask, but even internal people couldn't give me any specific answer about that. We must only wait. And wait... The F7's are imho still in test-production.

Do you know if any of F7 will be automotive qualified?
Dont know anything about that, but possibly not. No STM32 has automotive certificate as I know. But I can ask tommorow.
