Making esp32 working with ILI9488

Other Hardware Displays
1

Hello,

If anything from this point does not suit this site's regular texting I am sorry.

I have a problem with my display ILI9488, did some research on internet but have not found any solution.
Arduino forum does not allow me to post pictures due to my newbie account.

This is wiring and my userSetup, I have also defined which display I am using.

#define TFT_MISO 19
#define TFT_MOSI 23
#define TFT_SCLK 18
#define TFT_CS 15
#define TFT_DC 2
#define TFT_RST 4

If anyone can help me make it work I would be very grateful and it would mean a lot

That is all I have, if you need anything more I will post

Bodmer provides several ready-made User Setups e.g.
C:\Users\David Prentice\Documents\Arduino\libraries\TFT_eSPI\User_Setups\Setup21_ILI9488.h

I suggest that you start with his example. Connect all the ESP32 pins correctly. Run all of the TFT_eSPI examples.

But the first step in any "Displays" question is to post a link to the actual screen that you have bought.
And quote the User Setup Select e.g.
C:\Users\David Prentice\Documents\Arduino\libraries\TFT_eSPI\User_Setup_Select.h


#include <User_Setups/Setup21_ILI9488.h>           // Setup file for ESP32 and ILI9488 SPI bus TFT

This is the link of display I bought

I also have that tft_eSPI library and display is wired according to what I wrote above

#include <User_Setups/Setup21_ILI9488.h>
I have already selected that before I wrote this post

Hi, @Kamenkos
Welcome to the forum.

To add code please click this link;

What does your display do when you run your code?

Thanks.. Tom.... :smiley: :+1: :coffee: :australia:

It just goes white, but that is because LED pin, no changes on display, it is fixed white

Thanks for the link. Does your screen have the XPT2046 mounted ?

Yes, Setup21 is the correct setup for that screen.

I suggest that you check your wiring very carefully.
Then post a photo of your wiring. And add each wire colour to the wiring scheme. This helps readers (and you) check the wires.

Note that any header strip must be soldered.
Any connecting wires must be professionally crimped / soldered.

It is not mounted

I will check my wiring right away

Do you need scheme of wiring?

We know the scheme. It is described in Setup21.
However it is useful to edit #1 and add the wire colours for each signal. And the wire colours for the GND and VCC pins.

I don't know when you are permitted to post photos.
But simply checking each end of every coloured wire is a good exercise for you.

Since you don't have the XPT2046 chip mounted on the pcb, you don't need to worry about Touch functions.

David.

I checked my wiring and found that CS pin was unproperly wired, but display still refuses to work even after I got it in the right place
