DFPLayer reset and non repeat

userHead Account cancelled 2022-01-08 04:33:05 407 Views0 Replies
I have a project where I am displaying the verses of a song on a TFT display while playing the song using the DFPlayer module. I'm using a Nano Every and a Adafruit 3.5" TFT display. I copied the logic for the DFPlayer from a example I found on YouTube, it does not use the DFPlayer library but sends the commands via SoftwareSerial. Everything works except 2 things I would like to add.

I only want to play the song once then stop until I reset the Nano. Looking in the play() function it does use the repeat play command, execute_CMD(0x11,0,1);. I tried commenting it out and changing the parameters but it either doesn't play the song or continues to repeat,

I also want to reset the player when I reset the Nano, I used the command execute_CMD(0x0C, 0, 1); in setup, but that also doesn't seem to work.

Here is my sketch
Code: Select all
// mp3 player with TFT display
// Cycles through circles, and verses sync'd with song
// With Bit map image at end
// added DFPlayer

#include <SPI.h>
#include "Adafruit_GFX.h"
#include "Adafruit_HX8357.h"
#include <SD.h>
#include <SPI.h>
// for mp3 player
#include <SoftwareSerial.h>
SoftwareSerial mySerial(3, 4);
# define Start_Byte 0x7E
# define Version_Byte 0xFF
# define Command_Length 0x06
# define End_Byte 0xEF
# define Acknowledge 0x00 //Returns info with command 0x41 [0x01: info, 0x00: no info]
boolean isPlaying = false;
# define ACTIVATED LOW

// These are 'flexible' lines that can be changed
#define TFT_CS 7
#define TFT_DC 9
#define TFT_RST 8 // RST can be set to -1 if you tie it to Arduino's reset
#define SD_CS 10

// Color definitions
#define BLACK    0x0000

#define MAGENTA  0xF81F
#define YELLOW   0xFFE0 
#define WHITE    0xFFFF

#define MAX_BMP 10  // bmp file num
#define FILENAME_LEN  20 //Max filename length

 
File bmpfile;
