Arduino Uno: Cannot control ILI9341 LCD using Adafruit_ILI9341 library

Hello,
I am using this TFT LCD. I connected my Uno to the LCD as shown in the image on the Adafruit site, and I used this example to test my display.
My code always stops after ts.begin() fails; it seems like the STMPE610 controller fails to initialize. I noticed they defined a CS pin on pin 8 for this controller, but I do not see an additional CS pin on my module, and I do not see pin 8 on the Arduino connected to anything in the image on the Adafruit site.
I removed the STMPE610 code and ran the simple program below to turn the LCD blue, but the LCD still would not respond.

#include <SPI.h>

#include <Wire.h>

#include <Adafruit_ILI9341.h>

#define TFT_CS 10

#define TFT_DC 9

Adafruit_ILI9341 tft = Adafruit_ILI9341(TFT_CS, TFT_DC);

void setup(void)

{

Serial.begin(9600);

tft.begin();

tft.setRotation(1);

}

void loop()

{

tft.fillScreen(ILI9341_BLUE);

}

If you have a well lit, in focus picture of your wiring that clearly shows how all the connections are made that you could share, that might help. However, a jumble of Dupont cables that no one can follow is of no use whatsoever. Apologies for stating the obvious, but you'd be amazed at the dark, unfocused pictures showing a jumble of wires that go somewhere out of frame some folks produce.

Have you tried any of the samples in the library?
