I got my LVGL project to work on the ESP32-S3-Touch-LCD-4.3B device. I just copied the Touch-LCD-7 JSON file and modified the extra_flags to match the pins and values for the 4.3" version (based on the values from the esp_panel_board_custom_conf.h file in the 09_lvgl_Porting Arduino example from the demo files). I'm still trying to work out issues with screen jitter and such, which is probably due to needing double buffering or something |

Nice, if you found the right pins/plclk I can put it into the definitions so it will work out of the box! |

For sure, the only pin variations I found between the 4.3B and the 7 are the VBP and VFP being 16 for the 4.3B. The flash size also bumped the flash size to 16MB. Now I'm down to solving the jitter issue, which I can't seem to nail down. The LVGL porting examples in the Waveshare demos contain instructions that explicitly handle double buffering + full/partial/direct mode rendering, so I'm toying around with that. It may just be something as stupid as how I'm handling the tick in my code lol so I guess I'll see. |

I've resolved the jitter issue, and all my code is now working properly. I modified the original lvgl_panel_st7262_par.c to utilize double buffering and full rendering, then adjusted the PCLK value from 16 MHz to 14 MHz in the board JSON. https://github.com/xBurningGiraffe/Gauge_Dashboard/blob/main/esp32-s3touchlcd4p3.json - Board config |

i see you have support for the 7" version that is similar so should be a quick add.

i tried adding a board conf for it but i might have missed something as i just have a black screen where previously i got a display with the same project with board ESP32-2432S032C.
Thanks for a great project that really helps with these ESP32 Displays :)
