Hi !
I designed 8x8 sized module RGB led ws2811 this module working properly but when i go for adding extra modules i getting issue, so i want to add this modules so my code is not working for extra modules. please help me
#include <FastLED.h>
#include <SPI.h>
#include <SD.h>
#define NUM_LEDS 64 // LED number
#define DATA_PIN 6 // your data arduino pin
#define CHIPSET WS2811 // your LED chip type
#define CMD_NEW_DATA 1
unsigned char x = 8; // matrix x size
unsigned char y = 8; // matrix y size
File fxdata;
CRGB leds[NUM_LEDS];
void setup()
{
FastLED.addLeds<CHIPSET, DATA_PIN, GRB>(leds, NUM_LEDS); //see doc for different LED strips
// Serial.begin(BAUD_RATE); // when using Glediator via usb
Serial.begin(115200);
for(int y = 0 ; y < NUM_LEDS ; y++)
{
leds[y] = CRGB::Black; // set all leds to black during setup
}
FastLED.show();
pinMode(10, OUTPUT); // CS/SS pin as output for SD library to work.
digitalWrite(10, HIGH); // workaround for sdcard failed error...
if (!SD.begin(4))
{
Serial.println("sdcard initialization failed!");
return;
}
Serial.println("sdcard initialization done.");
// test file open
fxdata = SD.open("myanim.dat"); // read only
if (fxdata)
{
Serial.println("file open ok");
fxdata.close();
}
}
int serialGlediator ()
{
while (!Serial.available()) {}
return Serial.read();
}
void loop()
{
fxdata = SD.open("myanim.dat"); // read only
if (fxdata)
{
Serial.println("file open ok");
}
while (fxdata.available())
{
fxdata.readBytes((char*)leds, NUM_LEDS*3);
ledSort(2); //1-4 possible, set your first LED's position. Change the number: 1=TL(top left),2=TR(top right),3=BL(bottom left),4=BR(bottom right)
FastLED.show();
delay(50); // set the speed of the animation. 20 is appx ~ 500k bauds
}
// close the file in order to prevent hanging IO or similar throughout time
fxdata.close();
}
int ledSort (int modus) { //1=TL,2=TR,3=BL,4=BR, this function will rearrange the led array ;-)

}
}

}
for(int j = 0; j < x;j++) {

}
