lolin S3 pro with ILI9341

[ced31esp]

Hello,

After years of using a lolin D32 pro, I decided to switch with a lolin S3 Pro . Unfortunately I can't make my ILI9341 working . Could you help me please. I changed the setup 70B like this :
// Typical board default pins - change to match your board
#define TFT_CS 48 // 10 or 34 (FSPI CS0)
#define TFT_MOSI 11 // 11 or 35 (FSPI D)
#define TFT_SCLK 12 // 12 or 36 (FSPI CLK)
#define TFT_MISO 13 // 13 or 37 (FSPI Q)

#define TFT_DC 47
#define TFT_RST 21

It's not working.

It's always rebooting

My arduino version is 1.8.19 .

My program is working with a simple SD test program .

Maybe I'm using the wrong user setup file ?

Could someone give me his configuration with lolin S3pro and ILI9341 .
Thanks a lot.

Is it this one?

If so make note of the flash SPI mode:
16MB Flash (Quad SPI)

This is QSPI (or QIO) but you are using DSPI (mode:DIO, clock div:1).

Try changing this and it might just work.

[ced31esp]

Thanks for your answer
I don't have lots of possibilities .
Where should I change your setting ?
Thanks

[elgerg]

Ok, thats strange, can you try a generic S3 board and see if you can change that setting?

If thats not working you might have to raise a ticket/issue with WiMo.

[ced31esp]

I tried diferrent board on arduino but I can't change that setting too :-(

[ced31esp]

if anyone has already used a tft ili9341 with a lolin S3 pro, I appreciate your advice.

[elgerg]

Did you try a basic blink sketch just so you are ruling out any TFP_eSPI stuff?

It would be useful to determine if it is the flash mode or not.

If it crashes with just a blink sketch then you will want to get it working before jumping into this lib.

Hello sorry it was written in my first message but lost in other lines.
As I said, of course I tried hello world on serial and even a program to test the SD card. It works. That' why I jumped to the tft. My programm works on a lolin d32 pro with tft e spi library (m5 stack in the user setup same pinouts). But on this one its not working.
Thanks for your help

[elgerg]

Ah, sorry.

It would be interesting to know what board package version you are using. If it's above 2.0.14 you might be having the problem described here:
#3384

[ced31esp]

Thanks to your advice, my tft is working !
I add #define USE_HSPI_PORT in the file Setup70b.h

I changed the version of the board package from the last one to the 2.0.13. (Don't know if it was necessary).

I have one more problem now. It wasn't the case with my lolin d32 pro. I can't have at the same time the sd card and the tft working. I tested my sdcard on a program it's ok, I tested my tft it's ok too. But when I mixed both of them , it can't read something on the sd card and display it.

For example :

#include <TFT_eSPI.h> // Bibliothèque pour l'écran TFT
#include <SPI.h> // Bibliothèque pour la communication SPI
#include <SD.h> // Bibliothèque pour la carte SD

// SD pin
#define SD_CS 46

TFT_eSPI tft = TFT_eSPI(); // Initialiser l'écran TFT

void setup() {
Serial.begin(115200);
tft.begin();
tft.setRotation(1); // Rotation de l'écran (1 pour portrait)
tft.fillScreen(TFT_BLACK); // Effacer l'écran
tft.setTextColor(TFT_WHITE, TFT_BLACK); // Couleur du texte
tft.setTextSize(2); // Taille du texte
tft.print("Hello World");

// Initialiser la carte SD
if (!SD.begin(SD_CS)) {
Serial.println("Erreur d'initialisation de la carte SD !");
return;
}

// Ouvrir le fichier texte
File file = SD.open("/test.txt");
if (!file) {
Serial.println("Erreur d'ouverture du fichier !");
return;
}

while (file.available()) {
String name= file.readStringUntil('\n');
name.trim();
tft.fillScreen(TFT_BLACK); // Effacer l'écran
tft.setCursor(0, 0); // Positionner le curseur
tft.println(name);
delay(1000);
}

file.close();
}

void loop() {

}
Hello world is displayed then nothing.

Have a look at this
#2717 (comment)

[ced31esp]

Thanks, I have a look to the discussion above. I'd like to try the vspi and hspi but I have difficulties to find the pins on my lolin S3 Pro corrresponding.

For the TFT I set #define TFT_CS 48
#define TFT_MOSI 11
#define TFT_SCLK 12
#define TFT_MISO 13
#define TFT_DC 47
#define TFT_RST 21

in the program below from the discussion 2717, what pins others thant tft do I have to put spiSD.begin(18,19,23,5) according to my lolin S3 pro
CS: Pin
MISO: Pin
MOSI: Pin
CLK: Pin

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

#include <TFT_eSPI.h> // Hardware-specific library

TFT_eSPI tft = TFT_eSPI(); // Invoke custom library

File root;

int fileCountOnSD = 0; // for counting files

void setup(){
Serial.begin(115200);

spiSD.begin(18,19,23,5);
spiTFT.begin(14,12,13,15);

thanks for your reply

[ced31esp]

After a few tries, it seems ok with digitalWrite (SD_CS,HIGH)' same.with tft.
I 'll try more precisely and I 'll tell you.
Thx
