TFT 320QVT 9341 Display not working with mega 2560

I have TFT 320QVT 9341 Display and i connect it with arduino mega 2560.
vendors said display logic level is 3.3V then i make a logic level converter (voltage divider circuit with 12K and 22K resistors)

then i everything wired according to UTFT arduno library and powered in 5V. but no any result.

when i powered back LED in display it indicate only white screen.

Buy a proper 40-pin Adapter Shield for your Mega2560. Then plug your 40-pin display into the Adapter.

Yes, you can make your own Adapter from a Protoshield. Either with resistors or proper level converter chips. This is quite a lot of work. Your method should be fine too. But there are a lot of wires to get 100% correct.

The real mystery is "why not buy a display shield in the first place?" i.e. already got level conversion.

:smiley: you are correct but i got it before i know about it. my work place gave it to me. :slight_smile:

It is still easier to buy an Adapter from Ebay. Even a Protoshield + components is going to cost money.

Jumper leads, resistors and a breadboard is likewise fiddly and expensive.

i got screen that's mirrored how do i fix? im using arduino mega and tft screen

it sais about degrees but that don't work either.
