can i directly make my old uno circuit on my new due, my module im gonna put is based on SPI. ??? (i finally got it :))

Given the lack of detail you've provided on your old UNO circuit, I think it would be safe to say the answer is NO.

Also remember that an UNO is a 5V system whereas a DUE is a 3.3V system. You would need to take this into account when re-using 5V components/modules.

The Uno is a 5V device but the Due is a 3.3V device and you must take that into account when connecting to peripherals

module is 3.3v

5

also theres 5v too on power outputs

Maybe you could post your circuit / module schematic here so that we can better answer your question.

i can only change dc and rst. does other pins gonna change or just on the same number

I had a quick read of that project and I sort of lost the plot ...

I'm thinking that the display uses the SPI interface but the author starts talking about I2C at one point:

Now, for the i2c connections, hook up the SCL (Serial Clock) pin of the display to A13 (analog pin 13) on the Arduino and the SDA (Serial Data) pin to A11 (analog pin 11).

I have no idea what the author means by A13 or A11. However, the SPI clock is on pin 13 and MOSI is on pin 11.

If it's a 3.3V display, then it should work on a DUE. Connect up the SCK & MOSI SPI signals and choose which digital outputs you want to use for RES and DC and adjust the values in the code accordingly.

i dont have those pins

11

on lcd

12

also i cant upload to due. i change the setting to Duemilanove or Diecimila. but rx and tx doesnt flash or gets high
