So here is the deal i have been wrestling around with this for quite some time and I have finally decided to ask for help.

What I am trying to do is create a program that graphs the serial data coming in (one axis for starters, three if i or someone feels compelled) and also can save all the information being gathered from the Arduino. I haven't been able to figure out how to write all the data coming in to a text file right now. The path I am trying is to save it all to an array and then magically save that array.

Thanks

Please note I am VERY new to this

For reference the Arduino code:

#include <Ports.h>
#include <RF12.h>

typedef struct { // 14 bytes
        uint16_t ms;
    //int16_t accel;
        int16_t accelx;
        int16_t accely;
        int16_t accelz;
    int16_t pres;
} Payload;
Payload values;
boolean ACK;


void setup () {
    Serial.begin(57600);
  //  Serial.println("\n[rocket_REC.pde]");
    rf12_initialize(1, RF12_915MHZ, 212); // 915 Mhz, net group 212, node 1
}


void loop () {
 
  if (rf12_recvDone() && rf12_crc == 0 && rf12_len == sizeof (Payload)) {
      Payload* values = (Payload*) rf12_data;
    
   //   Serial.print(values->ms);
   //   Serial.print(',');
   //   Serial.print(values->accel);
   //   Serial.print('\n');
      Serial.print(values->accelx);
      Serial.print(',');
      Serial.print(values->accely);
      Serial.print(',');
      Serial.print(values->accelz);
      Serial.print(',');
      Serial.print(values->pres);
      Serial.println(',');
  }
}
