mipi dsi interface

Mon Nov 28, 2016 8:29 am

Hi there,

I'm quite new to the RPi business, so bear with me
I was wondering if it's possible to connect a touchscreen which has mipi dsi directly to the Raspberry Pi?

example:

If not which type of connector is needed for this to work ?

Regards,
Passie

I have seen other screens as well, like adafruit pitft.
So to me it looks like other screens are supported as well ?
But I could be wrong.

Uses the hardware SPI pins (SCK, MOSI, MISO, CE0, CE1) as well as GPIO #25 and #24. All other GPIO are unused. Since we had a tiny bit of space, there's 4 spots for optional slim tactile switches wired to four GPIOs, that you can use if you want to make a basic user interface. For example, you can use one as a power on/off button. See below for the link to get the optional tact switches, they're not included.

Thank you for your feedback.
To bad you can't get other display's to work with the RPi :(

Have to find another solution for my project.

You can use other displays for sure (search for my posts showing how to use DPI interface)! Problem with your nice smartwatch (?) screen is the MIPI interface! MIPI interface is (still) closed source on the RPi since it's handled by GPU firmware.

And, I bet your touchscreen is simple I2C and not MIPI.

haha, I don't have a smartwatch but just interested in technology.
At the moment i'm building 2 RPi's for my domotica setup, where 1 will be used for sending and receiving rf signals.
And will be placed in the closet.
The other one will be sitting on my desk which for this one i'm looking for a touchscreen which sends the commands to the first one.
Would be nice to have a touchscreen round or square. ( not sure on design yet )

Seems I have to dig a little deeper on this matter.
