2.4" TFT LCD // ILI9325

[shri360]

Hi there!

I'm trying to interface 2.4" TFT LCD with ESP32-WROOM-32.

Lcd model,

Connections
TFT ESP32
LDC_RST -- GPIO32
LDC_CS -- GPIO33
LDC_RS -- GPIO15
LDC_WR -- GPIO4
LDC_RD -- GPIO2
LDC_D0 -- GPIO12
LDC_D1 -- GPIO13
LDC_D2 -- GPIO26
LDC_D3 -- GPIO25
LDC_D4 -- GPIO17
LDC_D5 -- GPIO16
LDC_D6 -- GPIO27
LDC_D7 -- GPIO14
3.3V -- 3.3V
GND -- GND

After uploading code showing white screen. really don't know what I'm doing wrong.

The ILI9325 is not one of the supported displays. So it may not work.

Which driver have you used in the setup file?

Run the Read_User_Setup sketch and look at the serial output to see if the pins are correct.

@Bodmer thank you and I appreciate your response.

Finally it's working!!
i used MCUFriend library and followed this guide. https://forum.arduino.cc/t/help-mcufriend-3-5-tft-lcd-480x320-esp32-solved/559854/5?u=shripad_hegde

@shri360 @Bodmer the link no longer works, can you provide me with any other information on how you got the ili9325 LCD with the ESP-32-WROOM-32. really struggling to find any library that works

Copy and paste the link. It works for me.

@Gitman13264 , for ili9325 Display MCUFriend Library worked for me..

Here is basic code for the ili9325 using MCUFriend Library..

`#define LCD_CS 33 // Chip Select goes to Analog 3
#define LCD_RS 15 // LCD_RS = Register Select or LCD_CD = Command/Data goes to Analog 2
#define LCD_WR 4 // LCD Write goes to Analog 1
#define LCD_RD 2 // LCD Read goes to Analog 0
#define LCD_RESET 32 // Can alternately just connect to Arduino's reset pinCan alternately just connect to Arduino's reset pin

#include <SPI.h> // f.k. for Arduino-1.5.2
#include "Adafruit_GFX.h"// Hardware-specific library
#include <MCUFRIEND_kbv.h>
MCUFRIEND_kbv tft;
//#include <Adafruit_TFTLCD.h>
//Adafruit_TFTLCD tft(LCD_CS, LCD_CD, LCD_WR, LCD_RD, LCD_RESET);

// Assign human-readable names to some common 16-bit color values:
#define BLACK 0x0000
#define BLUE 0x001F
#define RED 0xF800
#define GREEN 0x07E0
#define CYAN 0x07FF
#define MAGENTA 0xF81F
#define YELLOW 0xFFE0
#define WHITE 0xFFFF

void setup()
{
Serial.begin(9600);
uint16_t ID = tft.readID();
if (ID == 0xD3) ID = 0x9481;
tft.begin(ID);
tft.setRotation(0);
}

void loop()
{
tft.fillScreen(YELLOW);
delay (1000);
tft.fillScreen(BLACK);
delay (500);
tft.fillScreen(MAGENTA);
delay (1500);
} `

Thanks for this man on arduino forum

okay link works now thank you so much, sorry to bother but did you change anything in the library files of MCu friend?

[shri360]

@Gitman13264 No need to change anything in the library.. make sure that same connections as mentioned in the example code that’s it.

#define LCD_CS 33 // Chip Select goes to Analog 3
#define LCD_RS 15 // LCD_RS = Register Select or LCD_CD = Command/Data goes to Analog 2
#define LCD_WR 4 // LCD Write goes to Analog 1
#define LCD_RD 2 // LCD Read goes to Analog 0
#define LCD_RESET 32 // Can alternately just connect to Arduino's reset pin

no idea why this error keeps popping up, have uninstalled the library and installed again, thanks for all your help. very much appreciated, also was your chip specifically the ESP-32_Wroom32
