Arduino 3.2 TFT SPI 240x320 v1.0 display doesn't work

Hello,
I have 3.2 TFT SPI 240x320 v1.0 display and i try many things to get it to work but nothing work...
Can you help me please?

Not me, but there are experts that could help you, if you provide some information, e.g. a link to your display.

You could start reading General Guidance and How to use the Forum

Welcome to the Forum, btw.

You could also report what you tried already, and what processor board you use.

Thank you and I found idetification number (HR4 8637S G3/4) and pdf "user manual"

Maybe this one: Waveshare 3.2inch Touch LCD Shield for Arduino?

I would expect it to work with Library MCUFRIEND_kbv, available with Library Manager.

But David will be able to help.

Sorry, it has a totally different pinout that in the 18326.pdf

But the pdf may be for the panel used by the board.

It is for Arduino Uno Display but i post picture of my display (sorry for quality).

Picture 1

Picture 2

And who is David?

Your pictures are ok, they show what we need to see. Your display has an SPI interface for both TFT and Touch.

It is better to post pictures as attachments. I use MS Paint to reduce resolution to 20% to reduce size to be able to post.

It looks similar to a display I have. I will need to check. It looks the same, but is 3.5" 480x320 with ILI9488.

David Prentice is the Author of the Library MCUFIEND_kbv. He answers most questions concerning TFTs.
Just be patient.

His actual last answer is here Troubleshooting a 2.8 SPI TFT display - Displays - Arduino Forum

I know it's SPI but I try libraries like TFT or ILI9341 and nothing working i thing its conection problem becouse i have Ardino Mega 2560 and no Arduino UNO

We are making progress! now we already know what processor you use!

Arduino MEGA has HW SPI on different pins, on 3x2 ICSP connector and on the double row connector.

I konw and i use it

Your pictures in #4 show a Red 3.3V SPI display.

You must use level shifters on every signal pin for Uno, Mega2560.

It is very important to provide accurate information. e.g. a Red pcb and not the Blue Waveshare shield

God invented shields. You can plug the Waveshare Shield into a Uno, Mega, Due, Zero, ...
If you use a Red 3.3V display, you must wire carefully. Use level shifters on 5V GPIO boards.

David.

You could also report what you tried already, and what processor board you use.

Ok, I can't help with sparse information.

Caution: MEGA IO pins are 5V, your display is 3.3V

Found that I have the 2.8" variant, without touch. Obviously I used it with Wemos D1 mini, some time ago.

@username3333,

Note that this topic is relevant for you: Troubleshooting a 2.8 SPI TFT display

It could be this display: Surenoo 3.2 inch 320*240 SPI Serial TFT LCD Module Display Screen with Touch Panel Driver IC ILI9341 for MCU

Jean-Marc's photos show how to make a neat Adapter for Wemos-Mini
You can make similar Adapters for 3.3V Zero, Due, Nucleo, ...

TFTLCDcyg has posted photos of "universal" Adapters to receive different TFT, OLED, ...

It takes a bit of time to solder headers to Protoboard or Protoshields.
Once done, you have correct and reliable wiring for your display.

Especially important if you need level-shifters e.g. with 5V Uno, Mega,

David.

Thanks and sorry i wasnt online,
meanwhile i found documentation for display (url) and you right it need 3.3v. In the page i found pins for Arduino Mega and libraries. Now im gonna buy level conversion module and see what happend.

May I suggest you the chip CD4050BE
