Tool/software: Code Composer Studio
Hi all,
I trying to log data to a sd card with a msp430fr2355. i used a combination of a few examples because there wasnt any for my microcontroller. the libary i am using now is FATfs for making files and HAL_SDCard use SPI. Te following code is my main:
#include <string.h>
#include "FatFs/ff.h"
#include "FatFs/diskio.h"
#include <stdio.h>
#include "driverlib.h"
#include "Board.h"
#include <msp430.h>
int fat_init();
int SDCard_init();
FIL file; /* Opened file object */
FATFS fatfs; /* File system object */
FRESULT errCode; /* Error code object */
FRESULT res; /* Result object */
uint8_t bytesRead; /* Bytes read object */
uint8_t read; /* Read bytes object */
DIR dir; /* Directory object */
DIR dir2;
FATFS test_for_new; // to check if a new file can be written
FIL test_file;
int result=1;
int main(void)
{
//initCLK();
WDTCTL = WDTPW+WDTHOLD;
__enable_interrupt();
f_mount(0, 0);
//volatile int i;
SDCard_init();
fat_init();
//f_mount(0, 0);
while(1)
{
unsigned int bytesWritten;
f_write(&file, "abcdefg \r\n", 32, &bytesWritten);
//for(i=50000; i>0; i--);
}
}
int fat_init()
{
errCode = -1;
while (errCode != FR_OK){ //go until f_open returns FR_OK (function successful)
errCode = f_mount(0, &fatfs); //mount drive number 0
errCode = f_opendir(&dir, "/"); //root directory
errCode = f_open(&file, "TEST.txt", FA_CREATE_ALWAYS | FA_WRITE);
if(errCode != FR_OK)
result=0; //used as a debugging flag
}
return 0;
}
When i run the script it seems te get stuck at FATinit. its probably lays within SPI because i could t see anything with a logic analyzer. But more than this i dant figure out. does anybody know where the problem can be? all the examples i have seen at this point doesnt support my microcontroller or is to deep in the code to get it working.
