Topic: Is there a "split function in arduino? (Read 678 times) previous topic - next topic


Hi. I need to get a vlaue inside a string with the comma delimiter. is it possible?


String Vnames  = "Roger, Mark, Rose, Paul"

how could I get the "Mark"  or the "Rose" for example?

Something like
vnameok = split(Vnames," , ")(2). Where the  comma is the delimiter and the (2)  is the 3th position.

Yes it is a C string function called "strtok()"
What it does is it reads the buffer and looks for a split character( , . : / ; -   ) really any character you want, and it will output what ever is before the split character.

I can't remember if the buffer needs to be null terminated or not, I think it does.

"Hello, it is 1:20 pm. "
Output = strtok( buffer, ",:" ); //"Hello"
Output = strtok( NULL, ",:" );// " it is 1"
Output = strtok( NULL, ".");// "20 pm"

Hi. Tks for answering. I think I can but could you give me an example about how to get the 3th pro exanple:


variable = "joh, mary,rose,joseph"

I have been searching for this function and strtok seems doesn't do this.

Am I wrong?
