Embedded FAT file system
PX5 FILE

Simple

The PX5 FILE embedded file system comprises one source file, px5_file.c, which can be easily added to any project. The only additional requirement is to set up the project’s include path so that px5_file.h can be located during compilation. At this point, PX5 FILE is ready for operation—no complicated projects and linker control file changes are necessary.

Sample code:

#include <pthread.h>
#include  <px5_file.h>

unsigned char     memory[1024];
unsigned char     buffer[512];
int               file_handle;


int    main()
{

ssize_t         bytes_read;
unsigned char   read_buffer[8];

    /* Start PX5 RTOS.  */
    px5_pthread_start(1, memory, sizeof(memory));

    /* Start PX5 FILE.  */ 
    px5_file_start();

    /* Open a volume.  */ 
    px5_volume_open(‘0’, physical_driver, NULL, buffer,sizeof(buffer);

    /* Open a file.  */ 
    file_handle =  open(“TESTFILE.TXT”, O_RDWR);

    /* Read 8 bytes from the file.  */ 
    bytes_read =  read(file_handle, read_buffer, sizeof(read_buffer));

}
