SIMPLE

The PX5 FILE embedded file system comprises one source file, px5_file.c, hich 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));
}
