Function for O over a serial.

I am a happy computer programmer and well never played around with a robot before. Being a computer programmer I am use to the computer standard ways of doing things. I wrote this for the robot

Code:

 #include <stdio.h>

#define AMOUNT_OF_LINES 1

int reprint(void)

{

int i,x,r;

int farray[200],*fa;

FILE *fp;

fp = fopen("c:\\text3.txt", "r");

fa = &farray[0];



for(x=0;x<123;x++) 

{                 

                  

    *(fa+x) = (fgetc( fp ));

     printf("%s",fa+x);

}

fclose(fp);

}

int write(void)

{

           int c,x,i,y,n, *sp, string[200];  

      sp = &string[0];

           FILE *fp;

           fp=fopen("c:\\text3.txt", "w");

    

    for(x=0;x<3;x++){

      scanf("%s",sp+x); }

      for(n=0;n<3;n++) {

      fprintf(fp,"%s",sp+n); } 

      fclose(fp);

}

int main() {

   int x;

   write(); 

    reprint();

    scanf("%d",x);

}

/*for loops not complete, still need to make another function */

Well as you can read its a nice file IO, I am looking to use the serial to O back to the computers hard drive and save and in looking in the source for the serial I found no O function back over its device. Maybe I just over looked it and its there or I will have to write it. If anyone has an idea or solution let me know. Also I think I might have to use fwrite instead of fprintf but no issues there. Dont complain if you do run it and find the garbage data I have not finished the fuction for the for loops yet. Thanks for your time and have a nice day!

Re: Function for O over a serial.

The code for the robot isnt exactly like standard C for a computer, you might want to look at the default code

And read the programming ref guide from IFI

Re: Function for O over a serial.

If I understand this is what you want. Just Printf all you info like you normally would. But write a custom app that reads those values and logs them to a text file. Is that what you want?

Re: Function for O over a serial.

Even simpler, forget a custom App, depending on the kind of data you're using a properly formatted printf(), Hyperterm and Excel are your best friend.

I had to monitor the PID response for last years robot and a bunch of numbers wasn't doing it for me, so I had a printf like this:

Code:

printf("%d,%d,%d,%d,%d",kp, ki, kd, error, output); // This is a loose guess at what it was

Then I told HyperTerm to save to a file, and let the robot run, then using Notepad++ (it handles large text files better than notepad does) I trimmed out the section I needed and imported to Excel as a CSV (Comma Separated Values) file. Then I re-saved to .xls and started graphing, thanks to Mark McLeod for that awesome tip.
