RS232 interface, DE2-70 board

Sorry code got screwed up here it is ;

void get_weight_from_uart(char * weight)

{

FILE* fp;

char in_char = 0;

int pointer = 0;

fp = fopen ("/dev/RS232", "r+"); //Open file for reading and writing

if (fp ==0)

{

printf("error");

}

if (fp)

{

while (1)

{

in_char = fgetc(fp); // Get a character from the UART.

// if ((in_char == '\n') | (in_char == '\r') | (in_char == 0))

// {

// fclose (fp);

// return;

// }

// else

// {

weight[pointer++] = in_char;

printf("0%0x\n",weight);

delay(1000);

// }

}

fclose (fp);

}

// return 0;

}
