Hello, sorry I am new here. Any ways, i have smashed some other codes together. TFT and ethernet controll ect. I got it to print what ever i want on startup. but for some reason no matter what i do i cannot get anything to happen in loop? not even clearing the screen! im so confused.
And before you say it yes i know i suck at coding and i did this in like a 2 hours lol
Any help appreciated.
code here
tft display: 2.8 ITDB02 Shield, V2
Ethernet Shield Moduel R3
EDIT:Arduino Mega
code here
But, your question is NOT on pastebin. Where do you want help? If here, post your code HERE.

Why are you declaring these variables, when you don't use them before they go out of scope?
void loop(){
int buf[318];
int x, x2;
int y, y2;
int r;
digitalWrite(51, LOW);
The only reason for putting the { on the same line as the statement that it goes with is to save line. You look pretty silly when you then follow that with a blank line.
You look pretty silly diddling with the SPI pins in loop(), too, since they are how the ethernet shield and the Arduino communicate.
SPI pins? 43-53 arent spi pins are they? im so confused lol
and like i said i suck at coding i came here for help bashing aint helping
50-53 are the Mega SPI pins.
If your shields are not Mega shields, you can add jumpers over to 10-13 so the shields can pick up the SPI signals there. Then leave 10-13 as INPUTs so other parts of your sketch don't mess them up.
Or they might pick them up on the ICSP header (SCK, MISO, MOSI anyway, and slave selects from elsewhere).
The lcd display works just fine with the demo code. what i dont get is why the loop in my code wont work, even after removing the interfearing SPI pins from the code.....

You made some code changes, and didn't show is the new code.
The new code does something, but you couldn't be bothered saying what it does.
You did something that should cause the loop() method to generate some output somewhere. You couldn't be bothered saying what you did.
And, yet, you want us to tell you what to change in the code? Doesn't seem likely, does it?
I just threw it all together from scratch. Im not sure how i botched that other one but this one works just fine.
Needs a little more work but the problem i had is gone now. good to go lol.
