I'm running a benchmark to compare performance between the 8080 parallel protocol using 8 lines vs 16 lines.

In 8-bit mode, everything works perfectly, and animations run smoothly without any issues. However, when switching to 16-bit mode, I'm encountering problems with animations: parts of the ...

Hi:

I can't comment on animation issues as my gui stuff is just infrequent as-needed updates, but I did use i80 mode for one project. I was using an Elecrow DLC35010R display/esp32s3 module with 3.5" 320x480 (ILI9488) and cap touch (FT6236-i2c). The ili9488 was configured for i80-16. I had a ...

Probably a speed issue. Tearing happens when the vsync and the display write overlap, but how visible that is in an animation depends on where the tearing happens in all the different frames: if it's more-or-less in the same location, the tearing is really obvious. Could be that the slower 8-bit ...

I don’t understand why, when I use the 8080 16-bit configuration, the LVGL animations show tearing, while using 8080 8-bit with the same display works perfectly.
I’m using the ST7789VI controller and ESP32-S3 module.

Static images look fine in both 8-bit and 16-bit modes.

This is how I have it ...

I would like to know if there is any example in ESP-IDF and ESP32-S3 that uses a TFT with 3-wire SPI (no D/C pin, 9 bit data) with LVGL

Check if your wiring matches the pin definitions in your code:
SCLK → GPIO 14 (TFT DCX)
MOSI → GPIO 47 (TFT SDA)
MISO → GPIO 38 (TFT SDO)
CS → GPIO 45 (TFT CSX)
RST → GPIO 12 (TFT RESX)
DC → GPIO 11
BKLT → GPIO 4


Yes, the wiring matches with the pin definitions.

The screen that I use is that ...

I'm trying to follow this example
https://github.com/espressif/esp-idf/tree/master/examples/peripherals/lcd/spi_lcd_touch
with a ESP32-s3 and the display NHD-2.4-240320AF-CSXP but I only see the backlight on the screen. The connection is:

I want to use an LCD screen with an esp32-s3 with SPI, the question is, should I use the gpios recommended by SPI_HOST (HSPI VSPI) or can I use others.
