Low memory available, mp3 shield and RTC module

khaled213 · November 3, 2018, 7:34am

hello friends i got a ( Low memory available, stability problems may occur. ) and the code doesnt work i didnt use serial print i use mp3.play

#include <SPI.h>

int x,h,m ;
void setup () { 
pinMode(5, INPUT); 
 Serial.begin(9600); //Begin the Serial at 9600 Baud
 //Print the message if RTC is not available
 if (! rtc.begin()) {
   Serial.println("Couldn't find RTC");
   while (1);
 }
 //Setup of time if RTC lost power or time is not set
 if (rtc.lostPower()) {
   //Sets the code compilation time to RTC DS3231
   rtc.adjust(DateTime(F(__DATE__), F(__TIME__)));
 }
 //start the shield
  sd.begin(SD_SEL, SPI_HALF_SPEED);
  MP3player.begin();

You could construct the filename.

(uncompiled and untested)

#include <SPI.h>
#include <SdFat.h>
#include <SdFatUtil.h>
#include <SFEMP3Shield.h>
#include <Wire.h> //include Wire.h library
#include "RTClib.h"
RTC_DS3231 rtc ;
SdFat sd;
SFEMP3Shield MP3player;
int x, h, m ;
void setup () {
  pinMode(5, INPUT);
  Serial.begin(9600); //Begin the Serial at 9600 Baud
  //Print the message if RTC is not available
  if (! rtc.begin()) {
    Serial.println("Couldn't find RTC");
    while (1);
  }
  //Setup of time if RTC lost power or time is not set
  if (rtc.lostPower()) {
    //Sets the code compilation time to RTC DS3231
    rtc.adjust(DateTime(F(__DATE__), F(__TIME__)));
  }
  //start the shield
  sd.begin(SD_SEL, SPI_HALF_SPEED);
  MP3player.begin();
}

void loop () {
  x = digitalRead(5);
  DateTime now = rtc.now();
  h = now.hour() ;
  m = now.minute() ;
  if (x == 1 ) {
    MP3player.playMP3 ("Tracksa.mp3") ;
    if (h >= 12) {
      h -= 12;
    }
    if (h == 0) {
      h = 12;
    }
    playNumberedHours(h);
    if (m) {
      playNumberedMinutes(m);
    }
  }
}

const char track[] PROGMEM = "Track";

void playNumberedHours(byte number) {
  char holdTrack[8];
  strcpy_P(holdTrack, track);
  byte prefixLen = strlen(holdTrack);
  itoa(number, holdTrack + prefixLen, 10);
  MP3player.playMP3(holdTrack);
  strcpy_P(holdTrack + prefixLen, PSTR("w"));
  MP3player.playMP3(holdTrack);
}

void playNumberedMinutes(byte number) {
  char holdTrack[12];
  strcpy_P(holdTrack, track);
  byte prefixLen = strlen(holdTrack);
  itoa(number, holdTrack + prefixLen, 10);
  strcat_P(holdTrack, PSTR(".mp3"));
  MP3player.playMP3(holdTrack);
  strcpy_P(holdTrack, PSTR("Trackmin.mp3"));
  MP3player.playMP3(holdTrack);
}

Seems to work.

class Tester {
  public:
    void playMP3(char* filename) {
      Serial.write('\'');
      Serial.print(filename);
      Serial.println(F("'"));
    }
} MP3player;

void setup () {
  Serial.begin(250000);
  for (byte h = 0; h < 24; h++) {
    playNumberedHours(h);
  }
  for (byte m = 0; m < 60; m++) {
    playNumberedMinutes(m);
  }
}

void loop () {}

const char track[] PROGMEM = "Track";

void playNumberedHours(byte number) {
  char holdTrack[8];
  strcpy_P(holdTrack, track);
  byte prefixLen = strlen(holdTrack);
  itoa(number, holdTrack + prefixLen, 10);
  MP3player.playMP3(holdTrack);
  strcpy_P(holdTrack + prefixLen, PSTR("w"));
  MP3player.playMP3(holdTrack);
}

void playNumberedMinutes(byte number) {
  char holdTrack[12];
  strcpy_P(holdTrack, track);
  byte prefixLen = strlen(holdTrack);
  itoa(number, holdTrack + prefixLen, 10);
  strcat_P(holdTrack, PSTR(".mp3"));
  MP3player.playMP3(holdTrack);
  strcpy_P(holdTrack, PSTR("Trackmin.mp3"));
  MP3player.playMP3(holdTrack);
}

it didnt work i dont know what is the problem ,,, the idea is when i push a putton it shows me the REAL TIME using RTC module and the mp3 played the files for example

the time now 12:43

input digital =1

mp3 playes ( tracksa.mp3) then (track12.mp3 ) then (trackw.mp3) then (track43.mp3) then plays (trackmi.mp3)

i hope the idea is clear

With that error description you are on your own.

Good luck.
