Using TFT_eSPI is causing the SD card to not function properly.

[bh3dkn]

When using both the TFT_eSPI and SD libraries with the esp32, the SD card will not function. Although the interfaces for these two modules are independent, how can the issue be resolved?

hello,

try this and adapt your tft wiring in the user setup and in the sketch,my settings are differents

user setup:

the sketch:

```

SPIClass spiSD(VSPI);
SPIClass spiTFT(HSPI);

#include <TFT_eSPI.h>      // Hardware-specific library
TFT_eSPI tft = TFT_eSPI(); // Invoke custom library

// -> Do your stuff!!


void setup(){
    Serial.begin(115200);
//(SCK,MISO,MOSI,CS);
spiSD.begin(18,19,23,5);//adapt to your wiring and setup
spiTFT.begin(14,12,13,15);//adapt to your wiring and setup

// Initialise the TFT screen
  tft.init();
  // Set the rotation before we calibrate
  tft.setRotation(2); 
  // Clear the screen
  tft.fillScreen(TFT_BLACK);
  

// -> Do your stuff!!


while (!Serial) {
    ; // wait for serial port to connect. Needed for native USB port only
  }

  Serial.print("Initializing SD card...");

  if (!SD.begin()) {
    Serial.println("initialization failed!");

  }
  Serial.println("initialization done.");

Previously, the pin layout of my SD card was the same as yours, and the order of the TFT pins was as shown in the diagram. I will test your method when I have some free time, and I appreciate your help.

[TangerineDreamer]

I forgot to say that the sd card i used was not a part of the tft,but real outside,hope it can helps somehow.

[bh3dkn]

My SD card is also an external one, but after integrating it with your program, it now functions properly. Thank you, brother!

[TangerineDreamer]

Glad to hear it!
can you test with the internal sd card too?
I remember a discussion with bodmer about it some years ago,he did something i think different
to declare the internal sd card ,saying the speed between sd card and tft was alright,but you know,
this forum is a nearly a lost treasure in the deep sea of internet memory... but for one who knows what to search about :)

I'm currently attempting to display a JPEG image on the TFT screen using an SD card, but I've been unable to do so. Even though I've managed to retrieve the name of the image via the serial port, the image still isn't being displayed on the screen.

[TangerineDreamer]

Have you tried with the bodmer examples?
The image could be placed in memory buffer before being pushed no?

have you tried this?
