if you can provide me a link to where the code is for the original firmware that was on it I can put together a display driver for your display. I am going to guess that the NV3047 would be similar to the NV3041a needing only a few small changes to be made. I also believe that the display might have an SPI 3 wire connection to configure a bridge IC. The only way to know is I need to see the data sheet and software that is made for the display. You also do not need to compile with these arguments They are not needed as all of this is hammered out by the build script. |

That's not from the company that made the display. |

Hello,
being new to the "forum" it might be a stupid question to ask because it might be only a L8 problem .
Above stated display came with a micropython version 1.19 with lvgl compiled but a broken imagetools implementation .
I wanted to build a audiobook for my son and decided for a newer micropython version with imagetools correctly compiled into it .
The display comes with an esp32-s3-wroom-1-n4r2 chip and i successfully compiled
LVGL (9.2.2) MicroPython (1.24.1) Binding compiled on 2025-05-19; Generic ESP32S3 module with ESP32S3 .
The board states a NV3047 (with xpt2046 as touch) driver to be used - no being able to find it if decided to build like this
python3 make.py esp32
BOARD=ESP32_GENERIC_S3
DISPLAY=rgb_display
INDEV=xpt2046
CONFIG_SPIRAM_SUPPORT=y
CONFIG_SPIRAM_SIZE=2MB
CONFIG_ESPTOOLPY_FLASHMODE_DIO=y
CONFIG_ESPTOOLPY_FLASHFREQ_80M=y
CONFIG_FREERTOS_HZ=1000
CONFIG_ESP_DEFAULT_CPU_FREQ_MHZ=240
PORT=/dev/cu.wchusbserial1440
BAUD=115200
--flash-size 4
deploy
RGBDisplay however refuses to initialize complaining about one of the parameters - long story cut short, am I completely mistaken (wrong build) or just missing something ?
Any input welcome as my wife is about to cut my screen time ;) ,
regards oliver
