esp32-p4 hdmi extension board

Postby chegewara » Tue Oct 22, 2024 7:03 am

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)
