Topic: [MIPI DSI-2] When will the Arduino support MIPI Display Serial Interface? (Read 1 time) previous topic - next topic

The Arduino MKR Vidor 4000 surprised me by having a MIPI camera connector,

But I was disappointed to see that it had no MIPI display support,

Many designs are being done with displays, and many of these monitors are parallel, many wires, slow, low resolution, and so on.

Knowing that many phones are being manufactured from years ago with the MIPI type connection screen, it would be wonderful if the Arduino offered a board with support for this type of screen.

Imagine what quality could achieve a project with Arduino with a display like the one used on an Iphone.

Look at this chip, it seems MIPI is here to stay:

Hi rtek,
Mipi DSI is feasible hooking up to HDMI connector and on the same it's also possible to drive lvds panels.
We don't have that on the roadmap yet but your request will for sure be taken into consideration. In the meantime someone in the community may want to take the challenge...
