ILI9341 Not working black screen

[adolfonovo]

Hello I have a 2.4 AzDelivery TFT display (8bit parallel) and I can´t get it work with the TFT_espi library. The manufacter says that is controlled by ILI9341 driver, and I test it with an Uno board and MCUfriend detects as a 0x9341, so I assume it is ok. Also all the examples with the UNo and mcufriend are working

I connect the ESP32 and define the user setup as follows:

// See SetupX_Template.h for all options available

#define TFT_PARALLEL_8_BIT
#define SPI_FREQUENCY  40000000
//#define SPI_TOUCH_FREQUENCY  2500000

//#define ST7735_DRIVER
//#define S6D02A1_DRIVER
//#define HX8357D_DRIVER
//#define ST7789_DRIVER

#define TFT_CS   33//azul  // Chip select control pin

#define TFT_RST  32//morado // Reset pin

//#define TOUCH_CS 21

#define TFT_WR   19//amarillo  // Write strobe control pin - must use a pin in the range 0-31
#define TFT_RD   23//naranja

#define TFT_D0   13//marron  // Must use pins in the range 0-31 for the data bus
#define TFT_D1   12//rojo  // so a single register write sets/clears all bits

#define LOAD_GFXFF  // FreeFonts. Include access to the 48 Adafruit_GFX free fonts FF1 to FF48 and custom fonts

#define SMOOTH_FONT

Wiring is triple checked and User_Setup_Select.h points to above settings

I have tried with all the available drivers without success.

As mention, I have another 3.5' display, and wire identically but with R61581_DRIVER and works perfectly

Do you know what else I have to ckeck?

TIA

Run the Read_User_Setup diagnostic sketch and check the output is as you expect. Does the output look OK?

Hi @Bodmer !! Yes, it is ok. Just found what was happening. It seem, this model needs both 3.3v and 5v .

Now its working. Thanks a lot and congrats!!
