Hi, Fernando.
First of all my congratulations for such a great project and for sharing it.
I am trying to emulate your project in Proteus, at the moment, without success, although I am encountering several problems and doubts that could be the source of my failure:

a) In your schematic, the pin numbers that accompany each signal label correspond to those of Arduino MEGA ?, in other words, is your schematic pin to pin compatible with Arduino MEGA?

b) In your schematic I have found a possible error and it is that the PE3 pin is used in two different signals, for D_IN and for SD_NSS.

c) According to the document "UTFT_Requirements.pdf" the signals RS, WR, RD, CS and REST can be governed by any free pin, with the exception that the RD signal "Must be pulled high (3.3V)", however, in your sources it is declared:

URTouch myTouch (6, 5, 4, 3, 2); // Pinos usados pelo "touch" no TFT shield

or
URTouch myTouch (7, 6, 5, 4, 3); // Pinos usados pelo "touch" no Ferduino Mega 2560

I wait for your comments. Best regards,

Hi!

Welcome Xavier!

Yes, the green number is equivalent to Arduino pins.

It's right. I'm using pin 5 to control SD card and touch screen.

The pin status is compatible for this two functions.

I'm using pin 5 for SD card because pin 53 is used for W5100.

You can see on code for Ferduino M.:

URTouch myTouch (7, 6, 5, 4, 3)


And:

const byte ChipSelect_SD = 5;

I'll mark this topic as solved since there's no feedback.
