RPi type A and ILI 9341

[N3KRoN]

I moved the SD card to another rpi and it worked! Apparently the problem is in my rpi model A, maybe some pins in it don't work and that's why there were problems...

Now everything works, thanks so much for your help!

I read the closed issues and found just like with my screen, but I can not even just display the information on it(
I don't need a screenshot much, I just need a display...

[nopnop2002]

I've been asked similar questions so far, but most of the time it's because the right driver isn't selected.

The appearance alone cannot determine the correct driver.

Use this to check.

Never believe the seller's information.

[N3KRoN]

I checked it on arduino uno and see ILI9341. And on arduino lcd excellent work, but on rpi doesnt(

I want to see this result

Your TFT is definitely ILI9341.

Works fine with PI model B(26 pin).

Check the wiring again.

This is mine.

[N3KRoN]

in my rasppberrry 26 pins
Can you check with 26 pins?

[nopnop2002]

Yes
26 pin model.

[nopnop2002]

Do you supply 5V to the TFT?

When a regulator(It's often AMS1117) is mounted on the back, it's operated 5V.
When a regulator is NOT mounted on the back, it's operated 3.3V.

[N3KRoN]

I have tried both 3.3 V and 5 V.
Please write the pinout of your connection, I will make exactly like yours.

[nopnop2002]

This is my pin out.

[N3KRoN]

But you use more pins in your schematic, I don't really understand how I can apply them in my

[nopnop2002]

But you use more pins in your schematic,

I don't understand your meaning.

What is my schematic?

I'm not using any more GPIOs.

[N3KRoN]

Did I get it right? The top row is for 26 pin RPi and the bottom row is for 40 pin? But with these first 4 pins in mind

[nopnop2002]

The top row is for 26 pin RPi and the bottom row is for 40 pin?

YES
RST CS RS WR has not changed.
Other than that, I changed the pins used.

[nopnop2002]

My pin,conf

#for 26pin header
#Number is WiringPi Number(NOT GPIO Number)
RST=7
CS=8
RS=9
WR=11
RD=15
D0=16
D1=0
D2=1
D3=2
D4=3
D5=4
D6=5
D7=6
#If your TFT is 8 bit Parallel,A definition after this isn't used.
D8=2
D9=3
D10=4
D11=5
D12=15
D13=16
D14=29
D15=30

[N3KRoN]

i select ILI9341
Maybe because I use retropie, now I will try to install it on a clean raspbian firmware

[N3KRoN]

Installed latest raspbian full, install wiringpi (https://github.com/WiringPi/WiringPi) and have this problem...

Installed a clean retropie, wiring and copied your driver again and again the same thing on the screen(
Something must be wrong with retropie...

[nopnop2002]

WiringPi may not work properly with retropie.

WiringPi is a very old library.

raspbian may have compatibility issues.
