I'm writing code to play sound with a wave shield by an IR remote. The problem is when i start the IR receiver after the wave shield loads it won't load the .wav files. if i start the IR receiver before the Wave shield it cancels out the IR receiver. Does anyone know why this is?
#include <IRremote.h>
#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
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 100
//char incomingByte;
// 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);
}
return free_memory;
