esp32-p4 hdmi extension board

[chegewara]

Hello community.
As i mentioned in other topic expressif is making DSI to HDMI extension board and i am the lucky one who have a sample.
Today i made some quick test, nothing fancy, but i would like to share the results.

First of all we have driver code in this bsp branch:
https://github.com/espressif/esp-bsp/tree/feature/hdmi

At the moment we have exposed only one resolution (1280x720x30hz), but no worries, we can find configurations for many other modes (up to 192x1080x60hz)
https://github.com/espressif/esp-bsp/bl ... _lt8912b.h

The simplest example display_usb_hid with connected mouse is utilizing about 12% CPU when have to refresh screen (moving mouse cursor), which is not bad in 1280x720.

I wish you all to get this extension asap and to make some cool projects.

PS here is picture from another demo code (taken with smartphone)

Thanks again for all the P4 updates.

Can't wait ! The p4 is really an exciting mcu !

Excellent news! Having DVI/HDMI and dual 400mhz makes this a potential perfect candidate for high-speed DAQ over HDMI.

It depends on exactly what the hardware will support for output to determine the actual data rate, but a Raspberry Pi Pico 2 can do 128MB/s.

As far as i know it is using 2 lane MIPI which should be 3Gbit capable.
Its hard to tell how its going to work in real life app.

Yes, it is cool.
Sad there is no driverless (actually app-less) solution to extend screen.

Also i wish that someone with passion and better than me can make a driver for this cheap extension to give us full set HDMI to P4 to HDMI

Would anyone be interested in this board? I'm planning to order some for myself (mabye trying to shrink the board a bit and getting rid of the LVDS pins) and if anyone wants one i can easily order some more and send them to you for the manufacturing price + shipping as a group-order.

Cheers!
