Library Errors in Arduino CookBook 2e - 8X8 array and Max7221

Projects Programming
1

I a trying to run the sketch 7.13 from the book for playing with an 8x8 array. This was a clear example of wiring. Code below.

/* 
 * Hello Matrix
 * by Nicholas Zambetti <http://www.zambetti.com>
 * Demonstrates the use of the Matrix library
 * For MAX7219 LED Matrix Controllers
 * Blinks welcoming face on screen
 */    
 
// the following two libraries are not provided with the 1.0 distribution
// see the text for links to the download
#include <Sprite.h>  
#include <Matrix.h>

const int loadPin  = 2;
const int clockPin = 3;
const int dataPin  = 4;

Matrix myMatrix = Matrix(dataPin, clockPin, loadPin); // create Matrix instance

void setup()
{
}

void loop()
{
  myMatrix.clear(); // clear display

  delay(1000);

  // turn some pixels on
  myMatrix.write(1, 5, HIGH);
  myMatrix.write(2, 2, HIGH);
  myMatrix.write(2, 6, HIGH);
  myMatrix.write(3, 6, HIGH);
  myMatrix.write(4, 6, HIGH);
  myMatrix.write(5, 2, HIGH);
  myMatrix.write(5, 6, HIGH);
  myMatrix.write(6, 5, HIGH);

  delay(1000);
}

I am getting the following errors.... I pulled the libraries from version 022 as they are not able to be located after searching the Arduino site. Now it looks like I need the wConstants.h library???? Is this correct. Anyone know where I can find it? Suggestions?

You might try reading the second section in the "Read This before posting a programming question..." that is pinned to be the first post. (hint, WConstants.h and WProgram.h were removed in IDE 1.0, replaced by Arduino.h).

From what I gather, the constants.h file was renamed to Arduino.h

I made this change in the matrix.cpp file but I now get a whole host of other errors. See below. I did notice the Backslash became a forwardslash when I changed the matrix.cpp file.

Please help!

At a guess then, you either have to track down a newer version of the library that works with the 1.0 IDE, or you have to switch to the older IDE.

Getting frustrated with DIY electronics.

Tried loading the code in ver022 and it appease to load fine, however no luck getting any sort of intelligent result from LED array.

Is anyone able to get a result from this wiring? If you happen to have some sample code I would appreciate it.

Thank you in advance,

I haven't run this code in a while, but I think it should still work:

https://github.com/WizenedEE/arduino/blob/master/LEDMatrix/LEDMatrix0/MAX7219/withoutLibrary/withoutLibrary.pde

(change the pin numbers as appropriate)

You could also try out the library I wrote:

https://github.com/WizenedEE/arduino/tree/master/libraries/LEDArray

The example should work but no guarantees

I used the LedControl library on Arduino v1.0 as it suited my needs better (No need of sprites) Arduino Playground - LedControl
