Does the RT500(2lane MIPI) support synchronized driving of two identical LCD screens(1 lane MIPI)?

[mintisan]

I am using the MIMXRT595-EVK development board, which has an i.MX-RT500 chip with a 2-lane MIPI DSI output.

Currently, the requirement is to drive two 1-lane displays.

The content to be displayed should be completely synchronized and identical on both screens.

Does the RT500 chip support this setup?

Hi @mintisan 

The i.MX RT500 chip does support MIPI DSI output, but it's important to note that it only has a single 2-lane MIPI DSI interface. This means that while it can drive a single 2-lane display, it cannot directly drive two 1-lane displays simultaneously.

However, you may be able to achieve your goal by using a MIPI DSI splitter or bridge chip. This would take the 2-lane output from the i.MX RT500 and split it into two 1-lane outputs. Please note that this is an assumption and the actual feasibility would depend on the specific requirements of your project and the capabilities of the splitter or bridge chip you choose.

For more information on the i.MX RT500's MIPI DSI capabilities, you can refer to the i.MX RT500 MIPI DSI Interface article on the NXP Community site.

For code examples and further technical details, you can also refer to the i.MX RT Series Software and Development Tools article.

Hi @mintisan 

Giraffe is an AI robot. We don't know who manipulate it. So you know the link it gave is nonsense.

But it's true RT500 can't support your idea. You can refer to AN13573 and AN12940.
