w00ng / esp32-s3-rgb-panel Goto Github PK

I'm on Windows 10, and I've just installed the latest master branch of the ESP-IDF on my system (commit hash 01d014c42def8d0c19e1ce55c07de6761e092ffa).
From within an ESP-IDF 5.0 PowerShell terminal, I've cloned the repository and tried to build it using the following commands:

git clone --recursive [email protected]:W00ng/ESP32-S3-RGB-Panel.git wywy-s3-rgb
cd .\wywy-s3-rgb\
git submodule update --init --recursive
cd .\examples\lvgl_demo\
idf.py build

Unfortunately this results in the following error:

How to resolve this? It seems that this repository is not working at the moment.

When going through the LVGL widgets demo as well as my own LVGL demo, I can see visible "tearing" / glitches.
In other words, you can see which parts of the screen are being updated.

I went through the code supplied in this repository and I noticed that the LVGL display driver was not configured to use Direct mode, which I think it should given that it has an RGB peripheral and you typically only want to update the buffer once the entire frame has been updated.

I changed lv_port_disp_init in components\lvgl\porting\lv_port_disp.c to:

• use a single draw buffer of LCD_WIDTH * LCD_HEIGHT * sizeof(lv_color_t) bytes
• allocate the buffer in PSRAM (MALLOC_CAP_SPIRAM) as it wouldn't fit in the internal RAM
  ** also used heap_caps_aligned_alloc instead of heap_caps_malloc (with 64 byte alignment), but that doesn't seem to make a real difference
• Set disp_drv.direct_mode = 1; before calling lv_disp_drv_register

For my own demo code this improved the experience quite a lot, but the framerate dropped for screens that only had a little animation going on.
For the LVGL widgets demo, the tearing itself became less noticable, but I got a lot of other glitches.

I think both issues might have to do with both LVGL and the RGB peripheral having to access to PSRAM.

Probably it would be better if the frame buffer would only be updated at most once "in between" frame transfers.
I've also posted a question on the Espressif forum related to this.

Please add a schematic.

Would you be so kind to share the part number for the vertical usb-c connector?

Thanks!

Lcd is not working . still is off state

DISP-PIN =3V or NC?
