Using a display through the Dsi port

Fri Jul 24, 2020 3:09 pm

I've got an old TFT display (with touch) and i wondering if i can use it from the dsi port like the official raspberry pi screen is doing?
If possible, what are the options?

do you know details of your display? Is it MIPI-DSI at all?

well, you need to have the data sheet for the timing and init sequence, a Raberry Compute Moduk (as there is the risk that yoir display will use more than 2-lane MIPI) and some knowledge in how to interfave it. Last but not least you will have to write a display driver ...

Sounds like I've got a lot of work to do and a lot to study :)
Few more questions
Is the compute module is for testing or it has a different job?
can i convert between different lane count?
Where can i best learn about writing driver?
