#define YELLOW          0xFFE0
#define WHITE           0xFFFF


TFTLCD tft(LCD_CS, LCD_CD, LCD_WR, LCD_RD, LCD_RESET);

const byte ROWS = 4; //four rows
const byte COLS = 3; //three columns
char keys[ROWS][COLS] =
{
  {'1','2','3'},
  {'4','5','6'},
  {'7','8','9'},
  {'*','0','#'}
};
byte rowPins[ROWS] = {44, 45, 46,47 };//ect to the row pinouts of the keypad
byte colPins[COLS] = {48,49,50};//the column pinouts of the keypad

Keypad keypad = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS );



void setup(void)
{
  Serial.begin(9600);
  Serial.println("8 Bit LCD test!");
  tft.reset();
  tft.initDisplay();
  tft.fillScreen(BLACK);
}


void loop(void)
{
 testdrawrects(RED);
    delay(1000);

char key = keypad.getKey();
    if (key)
    {
    Serial.println(key);
    }
}


void testdrawrects(uint16_t color)

{
   tft.fillScreen(WHITE);
   int h1=260;
   int w1=90;
   
   int h2=40;
   int w2=40;
   
    tft.drawRect(tft.width() -w1 , tft.height() -h1, 82 , 62, RED);
    tft.fillRect(tft.width()-w1 , tft.height() -h1 , 80, 60, YELLOW);
    tft.drawRect(tft.width()  -2*w2, tft.height() -2*h2, 62 , 52, RED);
    tft.fillRect(tft.width() -2*w2, tft.height() -2*h2 , 60, 50, YELLOW);
 

    tft.setCursor(40, 40);
    tft.setTextColor(color);
    tft.setTextSize(2);
    tft.println(keypad.getKey());
