Connect 3.5inch RPi Display 420x320 Pixel with XPT2046 to Arduino Mega 2560?

What use is assigning the pins if you have no software to drive it?

I think, read reply #4 again... and #8

Hi @ebp012

If you try to use this display without voltage level translation with your arduino without it you may damage it.

Best solution is to purchase a Pi. Or else a display that was designed for the Mega. I bought one that plugs right on top, like a shield, no jumpers.

All I need is a quick pin guide and where to connect each pin with to

...and level translators for each pin, and software...

Thats just a supply voltage, nothing at all to do with the IO pins.

All the logic pins on the Mega are 5V levels, do not connect to a 3.3V display without logic level conversion circuits on each pin.

What does the prototyping shield in my starter kit do? Or will I need to use resistors? If resistors are needed, how much?

Anyone?

Sounds like you have overstayed your welcome. :roll_eyes:

Complete answer has already been given more than once: Go and get a Raspberry Pi and connect your display to it. :grin:

Even with the microscope, I can´t find any pin numbers !!!! Who does this kind of things ??? Are they stupid o just laughing at us ???

Yeah !! We don´t need the story and biography of transistor, just tell where to connect them !!!!!

Thanks man !!! I can't believe the people who manufactures these products don`t realize that we need numbers !!!!! When I buy something, I want it to be S.P. (stupid proof) .

I could get pin number by using the RPi pinout and matching the connections to the RPi pinout then assigning those pin numbers of the RPI to the display connector.

I bet the connector has a small triangle on it to indicate pin 1.

The display seems to run on 5V and has built in logic level shifters.

Hello Everyone, i have a 3.5 RPI display SPI 480x320.
I want to use it for my School´s final project, with an arduino Mega 2560 but i didn´t know how to make the code and connections, if can somebody help me.
Thank you
