Hai friend
Can any one help me to clear this error . This is a simple pixel led animation and there is compile error in this
Following is the code


#include <Adafruit_NeoPixel.h>

#define NUM_COLS 8
#define NUM_ROWS 7
#define NUM_LED (NUM_COLS * NUM_ROWS)  // Calculate total number of LEDs
#define DATA_PIN D8
#define Speed 100
#define BRTNS 90

Adafruit_NeoPixel strip = Adafruit_NeoPixel(NUM_LED, DATA_PIN, NEO_GRB + NEO_KHZ800);

Ok thanks dear

4

mark as solution

5

Is this have RGB colour value ? eg0xFF00,

6

are you using ESP ? then forget everything spoken about "reducing"

7

yes ESP but this is only simple project but final project need more animation frame mor than 500 so I must think about memory

8

mark post #2 as solution, if you thankful for help

9

code is success fully load to ESP but LED are not glowing

Sorry Sorry :pray: It was working properly
Its mistake of me DATA pin Thanks a lot dear
