Finally able to compile the ILI9341 example with Arduino IDE.

tontito:
My TFT works well, also the colors are ok, just the RED is not really really RED.
In the SMING ILI9341 example there is a function tft_readId(void), that gives the device ID. What value it returns?

not read id.

My ID is: 0x00 LCD Flex cable TJC-024-9341.VO

i have test arduino nano and CD4050 level shifter. Same color problem.

All code remove same LCD color incorrect ESP8266 or Arduino Nano

TFT begin function

- Sat May 09, 2015 5:51 am #16972 I would really like to get a screen working withy ESPs...

I have a bunch of these SP1 screens that work with my nanos but when i hook them up to the ESP Arduino i get white screen.

I'm using these connections and the latest arduino environment. and the ILI9341 example compiles fine.
not working for me. 2.4" ili9341 tft lcd touch screen.

ESP8266 ili9341 2.4" LCD
GPIO 2 D/C
GPIO15 CS (and GPIO15 -> GND)
GPIO12 MISO/SDO
GPIO13 MOSI/SOI
GPIO14 SCK
3.3v -> pot LED
3.3v RESET
3.3v VCC
GND GND

does anyone have some suggestions?

I like ESP8266 and ESP8285 and ESP32

Links2004 is working on some very promising patches to the Adafruit_ILI9341 library, getting remarkable speed - the whole graphic demo runs in under nine seconds on the setup I've seen.
