TFT 3.5 ILI9488 esp32 S3 does not work & white screen

[mhmdrfki_13]

hello
I use tft 3.5 ILI9388 with ESP32 S3 by using TFT_Espi library with configuration
#define ILI9488_DRIVER // WARNING: Do not connect the ILI9488 display SDO to MISO if other devices share the SPI bus (TFT SDO does NOT tristate when CS is high)

#define TFT_BL 2 // LED back light control pin
#define TFT_BACKLIGHT_ON HIGH // Level to turn on backlight (HIGH or LOW)

#define TFT_MISO 13
#define TFT_MOSI 11
#define TFT_SCLK 12
#define TFT_CS 10 // Chip selection control pin
#define TFT_DC 8 // Data Command control pin

the reset pin is connected to the reset port on the esp32 s3
are the pins correct and appropriate?

because I have tried many times but always failed, I almost gave up but had to do it because this was a school exam assignment.

this is a picture of esp32 s3 and TFT 3,5

anyone can please help me

thank you

@mhmdrfki_13

reset pin is connected to the reset port on the esp32 s3

Connect it to some free Gpio pin.
Rest of the pins look ok.

I've done it but it still doesn't work, I've also tried suggestions from the forum with the same problem but it doesn't work either.

Were you able to solve it?? i have the same problem. I can turn on my screen, but is only white. I try with TFT_eSPI - User_Setup_Select - Setup21_ILI9488, but doesn't work.

I had the same issue ive tried 2 spi busses 3 different micro controlers and different spi speeds only the touch half on mine works i believe i have a faulty one but did you modify the correct config files?

[baltaridley]

Also i forgot to mention try using the ili9481 driver as they are very similar.

If you give me a week or 2 i could provide the correvt configs for the library to work.

Hi mhmdrfki_13

have a look at my site at https://thesolaruniuverse.wordpress.com and pick your combination. The ESP32S behaves the same as the ESP32C.
