Hi all,
for more that a week I am struggling to get the ILI9341 display working with ESP32 DevKit v1 and ESP Home.
The board is connected like this:
MOSI: GPIO 23
MISO: GPIO 19
SCK: GPIO 18
CS: GPIO 15
DC: GPIO 2
RST: GPIO 4
VCC (3.3V): 3.3V pin on ESP32
GND: GND pin on ESP32
LED: 3.3V pin on ESP32
In the Arduino IDE software, I am using the basic code for testing, if the display itself works fine or if it´s faulty. Everything works well, here is the basic code.
#include <Adafruit_GFX.h>
#include <Adafruit_ILI9341.h>
#include <SPI.h>
#define TFT_DC 2
#define TFT_CS 15
#define TFT_RST 4
Adafruit_ILI9341 tft = Adafruit_ILI9341(TFT_CS, TFT_DC, TFT_RST);
void setup() {
Serial.begin(115200);
tft.begin();
tft.fillScreen(ILI9341_BLUE);
}
void loop() {
// Doing nothing
}
This code works well and the display lights blue after uploafing the code.
I am absolutely not able to do the same in ESP Home.
esphome:

friendly_name: ESPHome TFT display
min_version: 2024.11.0
name_add_mac_suffix: false

ota:
- platform: esphome
wifi:
ssid: !secret wifi_ssid

spi:
clk_pin: GPIO18
mosi_pin: GPIO23
display:
- platform: ili9xxx
model: ILI9341
cs_pin: GPIO15
dc_pin: GPIO2
reset_pin: GPIO4
rotation: 0
invert_colors: false
lambda: |-
it.fill(Color(255, 0, 0));
I have tried this option, but it is not supporting lambda function.
lvgl:
buffer_size: 25%
Tried these options separately, different data rates, also not helping:
data_rate: 20MHz
OR
color_palette: 8BIT
Tried different models, TFT, ILI, nothing working:
model: TFT 2.4
OR
model: ili9341
Wiring is OK as it works in Arduino IDE.
Still gives me errors in the log and I am desperate how to make it to work.

Any ideas, what could be wrong?
