Problem using PROGMEM with pointer to an int array

Projects Programming
1

hey folks,
my arduino nano drives an LED Matrix. evrything works fine.
but my "outline path" ist too big for the SRAM, so i try to put it into PROGMEM.
Now reading values from this progmem array leads to totally wrong integers.
what am i doing wrong?

thx for helping!!

bye

void progStarsWarp() {

	const static PROGMEM int outlinePath[] = {30, 31, 29, 28, 27, 26, 36, 42, 43, 44, 45, 46, 25, 9, 8, 0, 1, 2, 4, 3, 16, 17, 56, 57, 91, 92, 101, 102, 111, 112, 121, 122, 162, 192, 193, 229, 230, 262, 263, 274, 275, 276, 277, 270, 269, 254, 239, 240, 241, 242, 243, 244, 253, 252, 251, 250, 249, 211, 210, 176, 177, 178, 179, 175, 161, 152, 151, 142, 141, 132, 131, 77, 72, 73, 74, 75, 76, 37, 31};
	int *pointerOutlinePath;

	FastLED.clear();

	for (unsigned int i = 0; i < 79; i++) {
		pointerOutlinePath = &outlinePath[i];
		int test = pgm_read_word(pointerOutlinePath);
		leds.m_LED[outlinePath[test]] = CRGB(getRandomColorValue(), getRandomColorValue(), getRandomColorValue());
	}

	FastLED.show();
	delay(60000);
}

Works for me:

void progStarsWarp();

void setup() {
  Serial.begin(115200);
  delay(1000);
  progStarsWarp();
}

void loop() {
}

void progStarsWarp() {
  const static PROGMEM int outlinePath[] = {30, 31, 29, 28, 27, 26, 36, 42, 43, 44, 45, 46, 25, 9, 8, 0, 1, 2, 4, 3, 16, 17, 56, 57, 91, 92, 101, 102, 111, 112, 121, 122, 162, 192, 193, 229, 230, 262, 263, 274, 275, 276, 277, 270, 269, 254, 239, 240, 241, 242, 243, 244, 253, 252, 251, 250, 249, 211, 210, 176, 177, 178, 179, 175, 161, 152, 151, 142, 141, 132, 131, 77, 72, 73, 74, 75, 76, 37, 31};
  int *pointerOutlinePath;

  for (uint8_t i = 0; i < 79; i++) {
    pointerOutlinePath = (int *) &outlinePath[i];
    int test = pgm_read_word(pointerOutlinePath);
    Serial.println(test);
  }
}

yeah... thx!!

problem was this:
leds.m_LED[outlinePath[test]]

should be:

leds.m_LED[test]
