MIMXRT1170-EVK How to setup MIPI Dsiplay in Video mode

[PIHL]

Hello,

I am working on a custom project with MIMXRT1170-EVK. I would like to drive a MIPI LCD screen that supports only Video mode but I can not get the setup right.

I tried code from csi_mipi_rgb_cm7 project example. But I am not sure if it is a Video mode of MIPI. Do you know where in the code I should search for a property that is responsible for mode configuration of LCD Display MIPI.

Regards,
Piotr

Hello Piotr,

your post was a while ago, but did you get your LCD screen working?
I think the difficulty is to transmitting DCS commands via video mode

Hello Piotr,

The MIPI DSI does support both command and video modes, as mentioned briefly in the i.MXRT1170 Reference Manual. The MIPI_DSI_Compliant_Test examples run in Video Mode.

I hope that this information helps!

Thanks,

how about csi_mipi_rgb_cm7 example code?

What property in setup is responsible for switching between video and command mode?

Regard,

Hello Piotr,

I might be misunderstanding your use case, but the i.MXRT1170 has a CSI input for video devices. The csi_mipi_rgb_cm7 project example then uses this port for a camera interface

If you will be using a display, you have on the i.MXRT1170 a MIPI DSI interface and a Parallel LCD interface. The MIPI DSI examples run in video mode and the driver does have a setting for the video/command mode.
