Tearing Effect signal

[Ricko]

Hi,

we are planning to use the display shown in the attached datasheet.

It is MIPI-DSI and also has a Tearing Effect Output signal. How is the Tearing Effect signal connected to the micro? I could not find any dedicated pin but from reading online about that signal, it looks like it is for syncronization which makes me think that is needs to be very high speed (MIPI-DSI speed?) and no latency. But there is no such pin on any of the micros we looked at.

Does that signal need to be connected to a specific pin?

If so, which one?

Thank you

Hello @Ricko ,

You do not need a specific pin for the tearing effect, a general gpio is enough. it is because the screen will update every 16.6 ms, so the latency of the tearing effect will have little to no effect on the refresh rate.

I hope this helps!
