splitting strings?
PostPosted: Wed Feb 19, 2014 6:29 am     Reply with quote
Hello,

i'm working on a projekt and i have a little problem, maybe someone can give me a hint...

i send a string to my pic -> FF#255#255#1 and now i have to store these values between the # into variables

so i splitted the string with strtok, this works fine, but how can i store the splitted values to strings?

for example:
direction =FF
speedX =255
speedY =255
light =1

here is the part with the strtok:

Code:

// split the string -> FF 200 255 1
char delimiter[] = "#";
char *ptr;

// first part
ptr = strtok(eingabe, delimiter);

while(ptr != NULL) {
   printf(usb_putc, "found: %s\r\n", ptr);
   // next parts
    ptr = strtok(NULL, delimiter);
}

}



thanks in advance
alex

hint: with your project open, press F11 to get the CCS C Help manual,locate strtok(),and see the example they show.It's very similar to what you want to do.

ok, this was a silly question, sorry :-)

i did it with strcpy and it works

Code:


        char delimiter[] = "#";
   strcpy(direction, strtok(eingabe , delimiter));
   strcpy(speedX, strtok(NULL , delimiter));
   strcpy(speedY, strtok(NULL , delimiter));
   strcpy(light, strtok(NULL , delimiter));

   printf(usb_putc, "Direction: %s\r\n", direction);
   printf(usb_putc, "speedX: %s\r\n", speedX);
   printf(usb_putc, "speedY: %s\r\n", speedY);
   printf(usb_putc, "Light: %s\r\n", light);
