can't access values of array

Projects Programming
1

hı I have an array which includes colors and when ı try to access values by index, ı got integer values

for below code I got

22:07:57.458 -> 31727

which is not related to my color value

#define BLACK 0x0000
#define NAVY 0xBDD6
#define DARKGREEN 0x03E0
#define DARKCYAN 0x03EF
#define MAROON 0x0CF3
#define PURPLE 0x780F
#define OLIVE 0xB383
#define LIGHTGREY 0xC618
#define DARKGREY 0x7BEF
#define BLUE 0x001F
#define GREEN 0x07E0
#define CYAN 0x07FF
#define RED 0xF800
#define MAGENTA 0xF81F
#define YELLOW 0xFFE0
#define WHITE 0xFFFF
#define ORANGE 0xFD20
#define GREENYELLOW 0xAFE5

int allColor[] = {DARKGREY,MAGENTA,GREENYELLOW,BLUE,OLIVE,ORANGE,BLACK};


void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);

    Serial.print(allColor[0]);
  



}

void loop() {
  // put your main code here, to run repeatedly:

}

Your program printed

allcolor[0]

allcolor[0] is dark gray

dark grey is 0x7BEF

0x7BEF is 31727 in decimal.

So what’s you problem?

Maybe you were expecting to see the value in hex?

void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);

  Serial.println(allColor[0]);
  Serial.println(allColor[0], HEX);

}

void loop() {
}

31727
7BEF

for Serial.println(allColor[0]); or Serial.println(allColor[0], HEX); I expect to get 0x7BEF value but the values I got different

5

I understand that Serial.println(allColor[1], HEX); gives last two number of my value and all values start with 0x. What about 3th and 4th number?

how your second print code give 7BEF ? for me it print just EF and I checked for other index it gives me just last two number

Did you change the definition of allColor[]?
