Simulating Arduino with ILI9341 screen

Can someone tell me what I'm doing wrong here? Screen is just blank.

Code:


#include <SPI.h>
#include "Adafruit_GFX.h"
#include "Adafruit_ILI9341.h"

// For the Adafruit shield, these are the default.
#define TFT_DC 9
#define TFT_CS 10
// Use hardware SPI (on Uno, #13, #12, #11) and the above for CS/DC
Adafruit_ILI9341 tft = Adafruit_ILI9341(TFT_CS, TFT_DC);

int lineno=0;

void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600); // open the serial port at 9600 bps
  Serial.print("Hello world.\n");
  Serial.print("Beginning TFT screen\n");
  tft.begin();
  Serial.print("TFT screen has begun\n");
}

void loop() {
  // put your main code here, to run repeatedly:
  tft.fillScreen(ILI9341_WHITE);
  yield();
  tft.setCursor(lineno, 0);
  tft.setTextColor(ILI9341_BLACK);  tft.setTextSize(1);
  tft.println("Hello World!");
  Serial.print("Line"); Serial.print(lineno); Serial.print("\n");
  lineno = (lineno+1)%tft.height();
  delay(300);
}


Hi.
Looks like the RST Pin definition is missing:

Code:

// For the Adafruit shield, these are the default.
#define TFT_RST 8
#define TFT_DC  9
#define TFT_CS  10
// Use hardware SPI (on Uno, #13, #12, #11) and the above for CS/DC
Adafruit_ILI9341 tft = Adafruit_ILI9341(TFT_CS, TFT_DC, TFT_RST);

Thanks!

Does SimulIDE support rotation of the display into landscape? I can rotate the item itself, but when I use tft.setRotation(1) in the code, it still draws to the display in portrait.

No, it's not supported.
Anyway the rotation in ILI9341 probably is not what you think.
But I'm not yet 100% sure how it works.
It would be great if someone could do some tests with a real one.

I recently ordered this LCD module from eBay, which it says is based on ILI9341 (but it is parallel, not SPI). I don't know a lot about it, but I may be able to run a small test for you if you can describe exactly what you want done. I do not have it yet but hopefully it will arrive in February.

Nice, I will prepare some code.

To have an idea of how hardware rotation works have a look at this post:
