mp3 player shield

i’m trying to compile the MP3_GPIO_Trigger but i have a problem

thats the message

Arduino: 1.8.5 (Mac OS X), Board: “Arduino/Genuino Uno”

/Users/benghelibter/Desktop/MP3_Playe/MP3_Player_Shield-V_1.5/MP3_Player_Shield-V_1.5/firmware/MP3_GPIO_Trigger/MP3_GPIO_Trigger.ino:28:24: fatal error: SdFatUtil.h: No such file or directory
#include <SdFatUtil.h>
compilation terminated.
exit status 1
Error compiling for board Arduino/Genuino Uno.

This report would have more information with
“Show verbose output during compilation”
option enabled in File → Preferences.

i do install the SdFat library

i do install the SdFat library

Then you do not do it correctly, because the error message is saying the compiler can't find it.

can you try to compile it at your program ?

MP3_GPIO_Trigger.ino (11.6 KB)

Why is
#include <SPI.h>
used twice in that code?

Why do you do this:-
//Add the SdFat Libraries
#include <SdFat.h>
#include <“SdFatUtil.h”>

When all the examples use
#include <SD.h>
When you replace those two lines with that one, and you have downloaded the SD libiary correctly it compiles.

i didn't do this code, its Sparkfun semple form the web site

Well it dosn't matter it is still crap.
