Hello, all:
I edited the java code in Oscilloscope to display the data received, in the
Node class, I have the following function to update data:
void update(int type, int reading) {
for (int i=Store-1;i>0;i--)
Data[type][i] = Data[type][i-1];
Data[type][0] = reading;
}
but when I tested it, I found that only Data[type][0] is updated, but all
the following data did not change (from Data[type][1] to Data[type][Store -
1]), can someone tell me what is the problem?
Thanks very much.
The edited Node class:
class Node {
/*
* 0 for temperature
*/
final static int Var = 5; // how many things to measure, tem etc, now
only measure temperature
final static int Store = 100; // how many data to store
/* The mote's identifier */
int id;
int[][] Data = new int[Var][Store];
//int dataStart, dataEnd;
Node(int _id) {
id = _id;
}
/* Data received containing NREADINGS samples from messageId * NREADINGS
onwards */
void update(int type, int reading) {
for (int i=Store-1;i>0;i--)
Data[type][i] = Data[type][i-1];
Data[type][0] = reading;
}
/* Return value of sample x, or -1 for missing data */
int getData(int type, int x) {
if (x < 0 || x >= Store)
return 0;
if(type<0 || type >= Var)
return 0;
else
return Data[type][x];
}
/*
// Return number of last known sample
int maxX() {
return 1;
}
*/
}
Best Regards,
CHEN WEIMING
