RS232 interface, DE2-70 board

[duffbuster220]

Can someone please help me? I have two weeks left in my senior design project and have to interface a Doran 2200 Scale to an Altera DE2-70 board using RS232. I have the configuration set-up on the board and have the scale transmitting data to the board (I know this based off the blinking LED that is telling me data is being received). I am using C code to run on a softcore processor that I have put in the FPGA and need to read data from the RS232 port. I have this code written so far;

Insert

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;
}

However when I read the data from those ports, I get the same thing printing over and over again which is;

05ffffa8

I am not sure whether or not I have the correct code written or why I am getting the same thing. Please advise.

Thanks.

The data read from the port maybe different each time but the code prints the location of weight over and over again, as in

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

Thanks for the quick response this is going to sound stupid because I am not very good with C but how do I print the values in weight?

printf("0%0x\n", weight[pointer-1]);
