Waveshare 2.4inch LCD Module, 65K RGB Colors, 240×320 Resolution, SPI Interface

[zombieplays]

I am trying to use this as the primary display on my raspberry pi 4. I followed all of the steps and when I reset my computer it changes the resolution on my actual monitor to the display's resolution and keeps the white screen on the LCD.

Edit: I figured out the solution separate from support. the wiki document fails to state that the raspberry pi must be named "raspberry pi" in order to install the necessary programs. it does this as it detects the name as the operating system.

Hello ! is there another library with which we can use the screen? I use the one you give on your site but the refresh time is too long. Thanks :)

Hello can we use this as the monitor of the pi zero v1. 3
If yes then please guide me.
Please do reply fast

I have this display and I don't know how to properly configure it on the Volumio2 system on the Raspberry Pi4b.
When connected to the GPIO, only the white backlight works.
Where can I find detailed instructions?

how to interface this display with arduino nano 33 ble sense board. none of the example code is compiling for this board

Would you have any known issues with this board or the supplied arduino code that results in a white screen? I'm using the LCD_2inch4 code, compiles fine, but after uploading to the arduino uno I simply get a white screen. Connections are per the wiki site.

Hello! Is there a way to use your own provided library to power LVGL? Looks like functions are completely different than the ones included on TFT_eSPI (the driver lvgl uses by default) - example setAddrWindow() is nowhere to be found, and the similar lcdWriteActiveRect() makes the code compile, but crash the whole system once that instruction is executed -, and even when I've declared the exact same pins your lib uses, no life signs have shown upon the display at all.
However, while compiling both example sketches provided in the library, everything to that point works fine... I'm confused.
Currently I am using an ESP-32 wroom module and a slightly different version of this screen, it's the 4" TFT SPI touch shield.
Thank you in advance!

FYI. I'm using it for the Raspberry Pi4!

I have the same problem with Arduino, I follow the connection steps like this in the wiki, using the code from LCD_2inch4, it compiles without errors but when I connect it to the Arduino it shows me only a white screen, the loaded script is not displayed.



Tengo el mismo problema con Arduino, sigo los pasos de conexión como esta en la wiki, utilizando el código de LCD_2inch4, compila sin errores pero al momento de conectarlo en la Arduino me muestra solo una pantalla en blanco no se visualiza el script cargado.

I'm trying to get one of these to work with an ESP32, also using the LCD_2inch4 code.
It now compiles and runs, but also with just a white screen.
There is nowhere to define the MOSI/DIN and SCLK pins.
Has anyone got this display to work on an ESP32? (or at all!)

can I use this display as monitor for Raspberry Pi 4?

I had the same problem of white screen even when supplied with external 3.3V power. It needs 5V to operate with Arduino. Dear WS you should correct your drawings.
It works fast with Ucglib, uncomment:
ucg(/*cd=*/ 7, /*cs=*/ 17, /*reset=*/ 8);
Adafruit for ArduinoMega works too but it's very slow.
Adafruit_ILI9341 tft = Adafruit_ILI9341(17, 7, 51, 52, 8, 3);
