Arduno Code to C/C++ for LED Cube

Hi Daniel,

Arduino code is C++ in an IDE with pin mapping and standard access to timers and other hardware features regardless of the microcontroller.  There are also numerous libraries providing access to sensors, LEDs, motors and such. 

So there is no conversion to C++ since it is already C++.  But it will be necessary to do all of the underlying register setting and library writing that an Arduino already provides.  In other words you will need to learn to implement basic C++ on a microcontroller - without this you will be lost.  It would be difficult to comment further without knowing the microcontroller you are using but my recommendation is to select one with good tutorials for getting started. You will need to learn how to use timers and set and change a gpio pin as a start.

I was instructed to change the code below into C or C++. I have to do it with out using digitalwrite. I tried something, to turn all LEDs (turnEverythingOn();) on with the code all the way at the bottom (bolded). Is anyone able to confirm that my code would work?

//initializing and declaring led rows

  int column[18]={13,12,11,10,9,8,7,6,5,4,3,2,1,0,A5,A4};

//initializing and declaring led layers

  int layer[4]={A3,A2,A1,A0};

  int time = 250;

void setup()

{

  //setting rows to ouput

  for(int i = 0; i<16; i++)

  {

    pinMode(column[i], OUTPUT);

  }

  //setting layers to output

  for(int i = 0; i<4; i++)

  {

    pinMode(layer[i], OUTPUT);

  }

  //seeding random for random pattern

  randomSeed(analogRead(10));

}

//xxxxxxxxxxxxxxxxxxxxFUNCTION LOOPxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

//xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

void loop()

{

  turnEverythingOff();//turn all off

  flickerOn();

  turnEverythingOn();//turn all on

}

void turnEverythingOff()

{

   for(int i = 0; i<16; i++)

   {

     digitalWrite(column[i], 1);

   }

   for(int i = 0; i<4; i++)

   {

     digitalWrite(layer[i], 0);

   }

}

////////////////////////////////////////////////////////////turn all on

  }

  {

    digitalWrite(layer[i], 1);

  while(i != 0)

  {

    turnEverythingOn();

    delay(i);

    turnEverythingOff();

    delay(i);

    i-= 5;

  }

}

{

}

{

DDRD = 0xFF; //setting outputs

PORTC.4 = 0xFF;
PORTC.5 = 0xFF;

}

I try to compile the code and I keep getting this error. Does anyone know how I could resolve this issue?

Thanks!
