Simulating the message you receive.

char myString[23] = "1;0;1;0;17;354"; // this is a C string, not String class...
/or like this: char myString = "1;0;1;0;17;354"; for example */

Hi Bulldog,

Could you explain the sttement (above)? I understand everything else about the code you posted except this. I think the "23" means you are allowing 23 spaces for the information but I do not understand the right side of the "=" sign. This is something like what might come through but why am I defining the payload? It could be from 20 to 1020 nd I do not understand the code above. Would you explain what this line is about and how the information in quotes relates to the variables being read in real time?

Way too cool! I appreciate the illustration. I need to get to sleep but I will play with it tomorrow evening after work. I just wanted to say thank you for giving me a guide.

1;0;1;0;17;354

something like this:

char myString[23] = "1;0;1;0;17;354";  // this is a C string, not String class...
/*or like this:  char* myString = "1;0;1;0;17;354";  for example */
int myValue[6]; //array to store all 6 values...


void setup() 
{
  Serial.begin(9600);
  char* token = strtok(myString, ";");  //tokenize the string
  for (int i = 0; i < 6; i++)  // works for your 6 values tokenized by ';'
  {
    myValue[i] = atoi(token); // take the tokenized value and store to the array
    token = strtok(NULL, ";");    // move the pointer to the next value
    Serial.println(myValue[i]);  //just print the value stored to the array
  }
}

void loop() 
{
  //
}

I hope that helps...

PS, since your value in the 6th position was greater than a byte, I used int

I am trying to parse typical node output data. When queried, my nodes send the analog data from each of the eight analog inputs. A typical output might look like:

1;0;1;0;17;354
1;0;1;0;17;422
1;0;1;0;17;423
1;0;1;0;17;519
1;0;1;0;17;527
1;0;1;0;17;439
1;0;1;0;17;484
1;0;1;0;17;406

The first byte is the node ID, and I do not care about the second, third, fourth, or fifth bytes. The sixth byte is the payload or data from an analog input. I would like to, ideally, parse the 1st and 6th bytes from each line and store the data in an array, possibly in flash memory on a Mega board. The problem is, I am so new to this, I am not sure how to begin to even present something to work on. My hope is that someone who recognizes this as being similar to a question from an earlier time can direct me to a sample that might serve to illustrate how this process can be made to happen. In the best of all possible worlds, someone may say "oh yeah, here's how you do it". Hey . . . a newbie can dream.

can you give an example of the message you are trying to parse.
