1  Using Arduino / Audio / Re: SdSimpleAudio Question on: December 26, 2012, 02:27:03 am
I got my code to work, it might not be the most efficient, but it is my first working Arduino project.  It was a christmas present for my wife.  I have four buttons that will be playing different sound bytes of my talking that she can press that have been put into a monkey that we take turns hiding.  I hope she likes it. 

Here's the code.
Code:
#include <SimpleSDAudio.h>
#define DEBOUNCE 5  // button debouncer
  int buttonState = 0;
  int buttonPushCounter = 0;
  int lastButtonState = 0;
void setup() {
  Serial.begin(9600);  //start serial comm.
  Serial.println("Welcome to the monkey business! Please press a button.");
  Serial.println("I will be playing different sounds whenever you select a button.");
  SdPlay.setSDCSPin(10);   //Using SD shield, need to be 10.
  if (!SdPlay.init(SSDA_MODE_FULLRATE | SSDA_MODE_MONO)) {     //fullrate, mono output
    while(1); // Error while initialization of SD card -> stop.
  }
  pinMode(10,OUTPUT);   //needed for shield
  pinMode(14,INPUT);    //button I'm trying to give my human input to play file
  pinMode(15,INPUT);
  pinMode(16,INPUT);
  pinMode(17,INPUT);
  }
void loop() {
    digitalWrite(14, HIGH);
    if (digitalRead(14) == LOW) {                        //This will cause music to be played.
      SdPlay.setFile("spoke7.afm");                        //play this file.
      SdPlay.play();                                       //play it now.
                                                         // Let the worker work until playback is finished
        while(!SdPlay.isStopped()){                          //apparently this has to do work son!
          SdPlay.worker(); }                                  //SdCard Hardhat zone.
    }
    digitalWrite(15,HIGH);
    if (digitalRead(15) == LOW) {                        //This will cause music to be played.
      SdPlay.setFile("spoke8.afm");                        //play this file.
      SdPlay.play();                                       //play it now.
                                                         // Let the worker work until playback is finished
        while(!SdPlay.isStopped()){                          //apparently this has to do work son!
          SdPlay.worker(); }                                  //SdCard Hardhat zone.
    }
    digitalWrite(16,HIGH);
    if (digitalRead(16) == LOW) {                        //This will cause music to be played.
      SdPlay.setFile("spoke9.afm");                        //play this file.
      SdPlay.play();                                       //play it now.
                                                         // Let the worker work until playback is finished
        while(!SdPlay.isStopped()){                          //apparently this has to do work son!
          SdPlay.worker(); }                                  //SdCard Hardhat zone.
    }
    digitalWrite(17,HIGH);
    if (digitalRead(17) == LOW) {                        //This will cause music to be played.
      SdPlay.setFile("spoke10.afm");                        //play this file.
      SdPlay.play();                                       //play it now.
                                                         // Let the worker work until playback is finished
        while(!SdPlay.isStopped()){                          //apparently this has to do work son!
          SdPlay.worker(); }                                  //SdCard Hardhat zone.
    }
}

Thanks for the help.

That really helps, and I knew that it was something really simple as changing the syntax of my code.  Thanks.  I thought the exact same thing when I woke up this morning.  I really need to do the notebook-by-the-bed thing.

It sure is nice to have people who want to help.  I really appreciate it.

I cleaned everything out that I think should not have been there.  But now, when I go to hit a button, nothing happens.  I have tried the generic pushbutton sketch in the examples and it's almost like the button sticks.  I guess that could be the problem.  I have other buttons, but they are not thru-hole.  I will have the try them tomorrow. 

Code:
Code:
#include <SimpleSDAudio.h>
#define DEBOUNCE 5                                  // button debouncer
void setup() {
  Serial.begin(9600);                                  //start serial comm.
  SdPlay.setSDCSPin(10);                            //Using SD shield, need to be 10.
  if (!SdPlay.init(SSDA_MODE_FULLRATE | SSDA_MODE_MONO)) {     //fullrate, mono output
    while(1); // Error while initialization of SD card -> stop.
  }
  pinMode(10,OUTPUT);   //needed for shield
  pinMode(14,INPUT);    //button I'm trying to give my human input to play file
  }
void loop() {
   int buttonState = digitalRead(14);      //so I can see output of buttonpress in serial monitor
   Serial.println(buttonState);            //ditto...continued.
   delay(2);                                       //time to collect "thoughts"
   if (14,LOW){ //This line makes the sketch play when set to HIGH whether hitting a button or
                 //not, and if I set it to LOW, it doesnt play at all.  I'm thoroughly confused,
                 //or maybe it is the lack of sleep and sustanance.  I think Ill sleep some more
                 //tomorrow.
    SdPlay.setFile("green.afm");        //play this file.
    SdPlay.play();                             //play it now.
   }
   // Let the worker work until playback is finished
  while(!SdPlay.isStopped()) {          //apparently this has to do work son!
    SdPlay.worker();                    //SdCard Hardhat zone.
 }
}

Thanks again community!  Sleepy time!
4  Using Arduino / Audio / SdSimpleAudio Question on: December 21, 2012, 05:55:44 pm
Im sorry for not posting this in the thread started by TuttTutt, but I needed the exposure.  I have a problem.  I can get the files to play when they are written into the basic example file, but when I change my file, that is where I get into trouble. 

I'd like to be able to play files from Sd and output them through PWM with the new library.  I just cannot for the life of me figure out how to make the buttons work.  It is driving me crazy.  I have used the WaveHC files as a starting point and also those from SimpleSdAudio.  I am stuck...

Ill upload the code.
Code:
#include <FatReader.h>
#include <SdReader.h>
#include <avr/pgmspace.h>
#include "WaveUtil.h"
#include "WaveHC.h"
#include <SimpleSDAudio.h>


SdReader card;    // This object holds the information for the card
FatVolume vol;    // This holds the information for the partition on the card
FatReader root;   // This holds the information for the filesystem on the card
FatReader f;      // This holds the information for the file we're play

WaveHC wave;      // This is the only wave (audio) object, since we will only play one at a time

#define DEBOUNCE 5  // button debouncer

// here is where we define the buttons that we'll use. button "1" is the first, button "6" is the 6th, etc
byte buttons[] = {14, 15, 16, 17, 18, 19};
// This handy macro lets us determine how big the array up above is, by checking the size
#define NUMBUTTONS sizeof(buttons)
// we will track if a button is just pressed, just released, or 'pressed' (the current state
volatile byte pressed[NUMBUTTONS], justpressed[NUMBUTTONS], justreleased[NUMBUTTONS];

/*
// this handy function will return the number of bytes currently free in RAM, great for debugging!   
int freeRam(void)
{
  extern int  __bss_end;
  extern int  *__brkval;
  int free_memory;
  if((int)__brkval == 0) {
    free_memory = ((int)&free_memory) - ((int)&__bss_end);
  }
  else {
    free_memory = ((int)&free_memory) - ((int)__brkval);
