Wemos D1 R32 with 3.5" TFT LCD Shield #2585

I have wemos d1 r32 and 3.5" TFT LCD Shield (ILI9486)... After I run Read_User_Setup, I got this

[code]
TFT_eSPI ver = 2.5.0
Processor    = ESP32
Frequency    = 240MHz
Transactions = Yes
Interface    = Parallel
Display driver = 9341
Display width  = 240
Display height = 320

TFT_CS   = GPIO 33
TFT_DC   = GPIO 15
TFT_RST  = GPIO 32
TFT_WR   = GPIO 4
TFT_RD   = GPIO 2

TFT_D0   = GPIO 12
TFT_D1   = GPIO 13
TFT_D2   = GPIO 26
TFT_D3   = GPIO 25
TFT_D4   = GPIO 17
TFT_D5   = GPIO 16
TFT_D6   = GPIO 27
TFT_D7   = GPIO 14

Font GLCD   loaded
Font 2      loaded
Font 4      loaded
Font 6      loaded
Font 7      loaded
Font 8      loaded
Smooth font enabled

I think my LCD Driver is ILI9486, but why it's written 9341?

I already wiring my Wemos D1 R32

And in User_Setup_Select.h I already try to uncomment one by one

But my LCD just get white screen and nothing happen

My shield like this image

After I run TFT_ReadWrite_Test with uncomment #include <User_Setups/Setup14_ILI9341_Parallel.h> // Setup file for the ESP32 with parallel bus TFT

The result is

 Pixel value written = 10
 Pixel value read    = 80

But the LCD just white screen

It looks like you have not commented out this line 30.

As noted in line 28: "Only ONE line below should be uncommented"

I've uncommented it and still get white screen... but when I use mcufriend_kbv, it works without any mod... but now the problem is the touchscreen doesn't work properly

I asked to comment out this line 30.

NOT uncomment it!

It should look like this: //#include // Default setup is root library folder

To be clear on what you have done, post your complete User_Setup_Select.h file and the setup file you want to use as ZIP files. (Drag and drop).

Assumed resolved.
