Using the SD card and the TFT_eSPI driver, the system crashes or in other cases performs a hard reset on loading

[suntchi2018]

I apologize in advance, I'm a beginner with this type of product and I don't know exactly what data could be useful for you to understand this strange behavior.
If you need the whole program and a complete debug and the User_setup.h.

Everything works fine until I add the SD.h library, if I use SPIClass spi = SPIClass(VSPI); before setup().
The system does not finish compiling:
c:/users/admin/appdata/local/arduino15/packages/esp32/tools/xtensa-esp32-elf-gcc/gcc8_4_0-esp-2021r2-patch5/bin/../lib/gcc/xtensa-esp32-elf/8.4.0/../../../../xtensa-esp32-elf/bin/ld.exe: libraries\TFT_eSPI\TFT_eSPI.cpp.o:C:\Users\admin\Documents\Arduino\libraries\TFT_eSPI\Processors/TFT_eSPI_ESP32.c:17: multiple definition of `spi'; sketch\Gestione_Stagionatore-ota.ino.cpp.o:C:\Users\admin\Documents\Arduino\Gestione_Stagionatore-ota/Gestione_Stagionatore-ota.ino:126: first defined here
collect2.exe: error: ld returned 1 exit status

If I don't put it, it compiles but ESP- WROOM 32 - 38 pin keeps resetting itself:

The version of all libraries are updated to the latest version. I'm using Arduino Ide 1.8.19

These are the libraries in use

#include <Wire.h>
#include <FS.h>
#include <SD.h>
#include <SPI.h>
#include <TFT_eSPI.h>
#include <WiFi.h>
#include <WebServer.h>
//#include <ArduinoOTA.h>
#include "AiEsp32RotaryEncoder.h"
#include <BME280I2C.h>
#include <TimeLib.h>

I'm using the ST7789 external display similar to the one inserted on the TTGO D-display the dimensions are 1.14' RGB 135x240 - DRIVER IC:ST7789V 4WIRE SPI PORT
With the following ports GND-VCC-SCL-SDA-RES-DC-CS-BLK
I look forward to your response if possible.

The library creates an spi instance for the VSPI channel unless #define USE_HSPI_PORT is in the setup file.

To create a different spi instance you need to use a different varaible name, for example:

SPIClass sdspi = SPIClass(VSPI);
    if(!SD.begin(22, sdspi)){
        Serial.println("Card Mount Failed");
        return;
    }

That was my problem!
I have applied that solution with different inctance.
tft.getSPIinstance()
has changed to
SPIClass sdspi = SPIClass(VSPI); ...
(!SD.begin(5, sdspi))
Now the ESP32_SDcard_jpeg demo works with SUNTON CYD 2.4inch_ESP32-2432S024C version.

Hi, thank you very much Bodmer for your help and your quick reply, but maybe I'm too incompetent, I tried to use pin 22 (GPIO8) for the SD card CS, but it still doesn't work, however the system does not crash, and this is a great improvement.
Where am I going wrong, if it's not too much trouble for your kindness.
This is the wiring diagram i used.

Ciao Bodmer,
nothing to do, I couldn't get the SD to work, it doesn't work I did a thousand tests but without results, he doesn't want to know. Leaving everything connected, rotary_encoder (which I need to manage the menu), the 6 relays, the SD and the display, if I use a test program for the SD it works, if I use a test program for rotary_encoder it works, if I try a program test to make the 6 relays work and the display always works without problems, if I use everything except the SD everything works, if I add the SD nothing works anymore.
I wanted to use the SD to avoid using the EEPROM, but I see that I'm not able to use it, I think it's just a dispute with the SD and honestly I'm not able to resolve.
It will mean that I will use the EEPROM, too bad!
Thanks anyway for your support.

See this example.
https://github.com/Bodmer/TFT_eSPI/blob/master/examples/Generic/ESP32_SDcard_jpeg/ESP32_SDcard_jpeg.ino

Note that the chip selects are set high before the SD and TFT are initialised to avoid conflicts. Try that example.

[Bodmer]

I just realised you have the SD card on the same SPI pins, so creating a new SPI instance will cause problems.

The SPI instance must be the same as is used by TFT_eSPI, so this should work:

tft.init()
if(!SD.begin(22, tft.getSPIinstance())){
    Serial.println("Card Mount Failed");
    return;
}

It is also a good idea to set the chip selects high as the start of setup as shown in the ESP32_SDcard_jpeg example linked to above.

Bodmer, thank you very kindly, but you are dealing with a naive, I can not solve the problem with this SD, I'm going crazy.
I tried using your solution but I can't get it to work.
I don't even want to waste your time you have already helped me so much and I thank you so much.
Unfortunately it's my fault, I pretend to do, but I don't have the experience I need in this environment.
I have to lower my expectations.
If you want, when I've finished it, I'll send you the project if you're interested in making salami and bresaola.

OH MY GOD, this solution solves my problem AT FIRST SHOT. Iam was struggling with this in few days. THANK YOU.
For the information:
I have Pico-Wave screen and RPi Pico. With this simple SD initialisation I get success status and simple example with new file "testing 1,2,3" WORKS.
I have ordered SDcard module in ten minutes before find this post.....
You definitely should include this info in main page :)
Thanks for GREAT library.
