Hello,
I hope you are all well.
I am trying to test my waveshield with my Arduino Uno board.
I am following this tutorial: waveHC Library | Wave Shield | Adafruit Learning System
The code I've been using, suggested by the tutorial is as it followos:
#include "WaveUtil.h"
#include "WaveHC.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
uint8_t dirLevel; // indent level for file/dir names (for prettyprinting)
//dir_t dirBuf; // buffer for directory reads
WaveHC wave; // This is the only wave (audio) object, since we will only play one at a time
void setup() {
Serial.begin(9600); // set up Serial library at 9600 bps for debugging
putstring_nl("\nWave test!"); // say we woke up!
putstring("Free RAM: "); // This can help with debugging, running out of RAM is bad
// Set the output pins for the DAC control. This pins are defined in the library
pinMode(2, OUTPUT);
pinMode(3, OUTPUT);
pinMode(4, OUTPUT);
pinMode(5, OUTPUT);
// if (!card.init(true)) { //play with 4 MHz spi if 8MHz isn't working for you
if (!card.init()) { //play with 8 MHz spi (default faster!)
putstring_nl("Card init. failed!"); // Something went wrong, lets print out why
sdErrorCheck();
while(1); // then 'halt' - do nothing!
}
// enable optimize read - some cards may timeout. Disable if you're having problems
card.partialBlockRead(true);
// Now we will look for a FAT partition!
uint8_t part;
for (part = 0; part < 5; part++) { // we have up to 5 slots to look in
if (vol.init(card, part))
break; // we found one, lets bail
}
if (part == 5) { // if we ended up not finding one 
putstring_nl("No valid FAT partition!");
sdErrorCheck(); // Something went wrong, lets print out why
while(1); // then 'halt' - do nothing!
}
// Lets tell the user about what we found
putstring("Using partition ");
Serial.print(part, DEC);
putstring(", type is FAT");
Serial.println(vol.fatType(),DEC); // FAT16 or FAT32?
// Try to open the root directory
if (!root.openRoot(vol)) {
putstring_nl("Can't open root dir!"); // Something went wrong,
while(1); // then 'halt' - do nothing!
}
// Whew! We got past the tough parts.
putstring_nl("Files found:");
dirLevel = 0;
// Print out all of the files in all the directories.
lsR(root);
}
/*
- list recursively - possible stack overflow if subdirectories too nested
*/
void lsR(FatReader &d)
{
int8_t r; // indicates the level of recursion
while ((r = d.readDir(dirBuf)) > 0) { // read the next file in the directory
// skip subdirs . and ..
if (dirBuf.name[0] == '.')
continue;
for (uint8_t i = 0; i < dirLevel; i++)
Serial.print(' '); // this is for prettyprinting, put spaces in front
printEntryName(dirBuf); // print the name of the file we just found
Serial.println(); // and a new line
if (DIR_IS_SUBDIR(dirBuf)) { // we will recurse on any direcory
FatReader s; // make a new directory object to hold information
dirLevel += 2; // indent 2 spaces for future prints
if (s.open(vol, dirBuf))
lsR(s); // list all the files in this directory now!
dirLevel -=2; // remove the extra indentation
}
}
sdErrorCheck(); // are we doign OK?
}
/*
- print dir_t name field. The output is 8.3 format, so like SOUND.WAV or FILENAME.DAT
*/
void printEntryName(dir_t &dir)
{
for (uint8_t i = 0; i < 11; i++) { // 8.3 format has 8+3 = 11 letters in it
if (dir.name == ' ') - continue; // dont print any spaces in the name*
- if (i == 8)*
- Serial.print('.'); // after the 8th letter, place a dot*
_ Serial.print(dir.name*); // print the n'th digit*_
* }*
* if (DIR_IS_SUBDIR(dir))
_ Serial.print('/'); // directories get a / at the end*_
}
/*
* play recursively - possible stack overflow if subdirectories too nested
*/
void play(FatReader &dir)
{
* FatReader file;*
* while (dir.readDir(dirBuf) > 0) { // Read every file in the directory one at a time*
* // skip . and .. directories*
* if (dirBuf.name[0] == '.')*
* continue;*
* Serial.println(); // clear out a new line*
* for (uint8_t i = 0; i < dirLevel; i++)
_ Serial.print(' '); // this is for prettyprinting, put spaces in front*_
* if (!file.open(vol, dirBuf)) { // open the file in the directory*
* Serial.println("file.open failed"); // something went wrong :(*
* while(1); // halt*
* }*
* if (file.isDir()) { // check if we opened a new directory*
* putstring("Subdir: ");*
* printEntryName(dirBuf);*
* dirLevel += 2; // add more spaces*
* // play files in subdirectory*
* play(file); // recursive!*
* dirLevel -= 2; *
* }*
* else {*
* // Aha! we found a file that isnt a directory*
* putstring("Playing "); printEntryName(dirBuf); // print it out*
* if (!wave.create(file)) { // Figure out, is it a WAV proper?*
* putstring(" Not a valid WAV"); // ok skip it*
* } else {*
* Serial.println(); // Hooray it IS a WAV proper!*
* wave.play(); // make some noise!*
* while (wave.isplaying) { // playing occurs in interrupts, so we print dots in realtime*
* putstring(".");*
* delay(100);*
* }*
* sdErrorCheck(); // everything OK?*
// if (wave.errors)Serial.println(wave.errors); // wave decoding errors
* }*
* }*
* }*
}
Unfortunatly, when I try to Verify/Upload, an error is given which states that 'sdErrorCheck was not declared in this scope.
Does anybody knows why and what I should do?
Many thanks for your help.
