Hi guys, I am currently trying to build a simple mp3 player using an sd card to store the music files and a PIC18f14k50 and a vs1011 decoder.
I am using the Petit FAT File System in order to do it (as it seems the simplest that way..)
Petit FATfs:
I have tried to use the sample PIC24 Sample project as a guide (you can download it from the website).
My code from MPLAB (v8.86) is shown below:
#include "p18f14k50.h"
#include "diskio.h"
#include "pff.h"
#include "string.h"
//Configuration bits set in settings.
//prototypes
void wdtdisable (void);
void oscsetup(void);
void spisetup(void); //SPI setup in FSConfig.h
void main (void){
wdtdisable();
oscsetup();
TRISC = 0;
FATFS fatfs; /* File system object */
DIR dir; /* Directory object */
FILINFO fno; /* File information object */
WORD bw, br, i;
BYTE buff[64];
disk_initialize();
while(1)
{LATCbits.LATC0 = 1;}
}
void wdtdisable (void){
WDTCONbits.SWDTEN = 0; //disable watchdog timer, might be able to use #pragma config WDTEN = OFF at the top
}
void oscsetup(void){
// Setting up internal oscialltor for 32MHz
//using primary clock so that 4xPLL can be used
OSCCONbits.SCS0 = 0;
OSCCONbits.SCS1 = 0;
OSCCONbits.IDLEN =0; //device enters sleep mode on "sleep" instruction
OSCCONbits.IRCF = 0x6; // setting Internal oscillator to 8MHz (so 4xPLL can be used)
OSCCONbits.OSTS =0; // Device running from High frequency internal oscillator
OSCCONbits.IOFS = 1; //Make High frequency oscillator stable
OSCTUNEbits.SPLLEN = 1; //Enable PLL
}
The output console says that there is a syntax error on the "FATFS fatfs;" line. When I remove that line it complains about the next one, until I remove the "BYTE buff[64];" line.
Can you guys help!???
Thanks in advance!
