Dear,

I have two problems: 1) SD Card cannot mounted
2) Screen display blue color.

On Arduino IDE 2.3.5 with this screen: https://fr.aliexpress.com/item/1005008263739345.html
Library esp32 (v2.0.17) i use GFX library which works fine with others model of screen, here it's ST7262:
https://sourceb.in/Cg85xIg4Yy

I follow this tutorial: https://www.waveshare.com/wiki/ESP32-S3 ... #Resources

and i try demos, compilation failed , ex: project 08_DrawColorBar i get this error: /home/james/Arduino/libraries/ESP32_Display_Panel/src/drivers/lcd/esp_panel_lcd.cpp:14:10: fatal error: esp_memory_utils.h: No such file or directory
#include "esp_memory_utils.h"
^~~~~~~~~~~~~~~~~~~~
compilation terminated.
exit status 1
Compilation error: exit status 1
for this project 03_SD_Test:

Thank you for your help

The library is written for arduino-esp32 v3.x. The header it is looking for is part of IDF5.
If you want help with the SDCard you need to provide a lot more information.

2) the screen display now

For my SDCard, its formatted with FAT32

Code: Select all

SPIClass spi2(HSPI);

  spi2.begin(12, 13, 11, 4);
  if(!SD.begin(4,spi2)){
    Serial.println("Card Mount Failed");
    return;
  }

What SPI is the display using? The default bus is typically HSPI. Try using FSPI (aka bus0) for the SD card instead.
Does the SD Card work if you run just a basic example with reassigned pins?
The SD library is not set up to use ExFAT, so you should reformat the card to FAT32 if needed.

SD card is formatted with FAT32. i try this link i get :

What is your hardware? Some sdcard modules may be set up as SDIO (aka SD_MMC). Some don't have pullups on the necessary pins.

Hi, I think I have the same product a waveshare esp panel 7 inch, the 2 examples: "03_SD_Test" and "08_DrawColorBar" work for me, you have to use the libraries downloaded with the examples, any update no longer allows you to use the examples, including lvgl.
