RS232 interface, DE2-70 board

Thanks for the help I had a friend look at it as well and we came up with a working code for those that would need help from these posts, the code came out as below which is a function that I called in my main program to give back the weight;

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 == '^') | (in_char == 0))

{

weight[pointer] = 0;

fclose (fp);

return;

}

else

{

weight[pointer++] = in_char;

// weight[pointer] = 0;

// printf(weight);

// delay(1000);

}

}

fclose (fp);

}

// return 0;

}

Thanks for the help.
