Still no code tags.

BulldogLowell · December 20, 2017, 5:43pm

this resolves to a pointer:

PixelArray

this returns an int:

analogRead(A0)

see any problem with that?

Maceraperest · December 20, 2017, 5:46pm

how to turn.

BulldogLowell · December 20, 2017, 5:56pm

Maceraperest:
how to turn.

start with a working example sketch for your TFT display... there are innumerable issues with your code as it is.

Maceraperest:
#include "SPI.h"

#include "ILI9341_due_config.h"
//...

so, this is totally different than what you previously posted.

What does this supposed to represent?

How can you expect help if you cannot bring yourself to give more information about your issues?

does it even compile?

what happens?

Maceraperest · December 20, 2017, 6:13pm

there is no compilation problem, the problem is not a placement between 120 and 240 pixels

 for(j = 120; j < 240; j++)
    {    
    tft.drawPixel(j, a, tft.color565(PixelArrai[i],PixelArrai[i],PixelArrai[i]));  
    }

    delayMicroseconds(0.001);

What kind of argument does this function take?

gfvalvo · December 20, 2017, 6:29pm

What, exactly, do you expect to be in elements 128-239 of PixelArray[] and PixelArrai[] given that you only defined them with 128 elements?

delayMicroseconds(0.001);

Seriously? A 1 ns delay? Unlikely even if delayMicroseconds() took float arguments, which it doesn’t.
