Controlling single LED, Matrix style

#include "Arduino_LED_Matrix.h"

ArduinoLEDMatrix matrix;

void setup() {
  matrix.begin();
}

uint8_t frame[8][12] = {
  { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 },
  { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 },
  { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 },

  { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 }
};

void firstled(){
//frame[row][col]
  frame[0][0] = 1;
}

void secondled(){
  //frame[row][col]
  frame[1][1] = 1;
  frame[1][2] = 1;
}
void loop(){
firstled();
matrix.renderBitmap(frame, 8, 12);
delay(2000);
secondled();
matrix.renderBitmap(frame, 8, 12);
}

Using the Matrix tool.

#include "Arduino_LED_Matrix.h"
#include "Demo.h"

ArduinoLEDMatrix matrix;

void setup() {
  matrix.begin();
}

void loop(){

  matrix.loadWrapper(Demo, 0);
  matrix.play();

  delay(500);
}
