I need array assistance.

jestal:
Here's my code, but it doesn't seem to run.
My goal is to collect the data every one millisecond.
Hardware is Arduino Ethernet.
I will be adding 6 discrete inputs to the collection once i get this part working.
I'll also later add code to dump all the data to a PC that is running VB, over ethernet.

const int analogInPin = A0;  // Analog input pin that the potentiometer is attached to

int MyArray1[700];
int MyArray2[700];
int MyIndex = 1;

void setup() {
 // initialize serial communications at 9600 bps:
 Serial.begin(9600);
 delay(300);
 Serial.println("Here we go.");
}

void loop() {

if (MyIndex < 600){
   MyArray1[MyIndex] = millis();
   MyArray2[MyIndex] = analogRead(analogInPin);
   //Serial.println(MyIndex);
 }

if (MyIndex == 600){
   Serial.print(MyArray1[2]);
   Serial.print(", " );
   Serial.print(MyArray2[2]);
   Serial.println("");
 }

MyIndex = MyIndex + 1;
 
}

The problem is that your defining of int MyArray1[700]; and int MyArray2[700]; takes up 2800 bytes of SRAM, where as a 328p based arduino board only has 2,048 bytes avalible in total. So you see the fundamental problem here?
