I am trying to get data from D6T Omron thermal sensor. It works fine with both Arduino and Processing when I connect it to pc directly. However, it seems to always cannot read my last data in my data array when i use Xbee on them. It results in a NaN for my last data in my array in processing display [Fig 1].
Anyone having any thoughts on this? Any help will be much appreciated! =D
Another problem i having here is that i was trying to make a popup window when my sensor senses a sum of 34*4 in the center pixels with no success currently. The last data in the array returns in NaN error again and the program is not responding after that. [Similar with Figure 1.] D:
It actually works fine until we reach this stage "Serial.write(0x03)" from Arduino to processing when it senses a sum of 34*4 in the center. I am confused. Any idea on how to improve that? =) Thanks a lot in advance!
Attached below is my code (Arduino sketch):
#include <Wire.h>
#include <WireExt.h>
#define D6T_addr 0x0A
#define D6T_cmd 0x4C
int rbuf[35];
float tdata[16];
float t_PTAT;
float top_sum, bottom_sum, left_sum, right_sum, center_sum, center_row_sum;
void setup()
{
Wire.begin();
Serial.begin(9600);
Serial.flush();
}
void loop()
{
int i;
if (Serial.available() > 0) {
int inByte = Serial.read();
if (inByte == 0x0001) {
Wire.beginTransmission(D6T_addr);
Wire.write(D6T_cmd);
Wire.endTransmission();
if (WireExt.beginReception(D6T_addr) >= 0) {
i = 0;
for (i = 0; i < 35; i++) {
rbuf[i] = WireExt.get_byte();
}
WireExt.endReception();
t_PTAT = (rbuf[0]+(rbuf[1]<<8))*0.1;
for (i = 0; i < 16; i++) {
tdata[i]=(rbuf[(i*2+2)]+(rbuf[(i*2+3)]<<8))*0.1;
}
output_csv();
delay(250);
}
top_sum= tdata[0] + tdata[1] + tdata[2] + tdata[3];
bottom_sum= tdata[12] + tdata[13] + tdata[14] + tdata[15];
right_sum= tdata[0]+ tdata[4] + tdata[8] + tdata[12];
left_sum= tdata[3] + tdata[7] + tdata[11] + tdata[15];
center_sum= tdata[5] + tdata[6] + tdata[9] + tdata[10];
center_row_sum= tdata[1] + tdata[2] + tdata[5] + tdata[6] + tdata[9] + tdata[10] + tdata[13] + tdata[14];
if (center_sum>34*4)
{
//Serial.flush();
Serial.write(0x0003);
delay(100);
}
}
}
}
void output_csv() {
for (int i = 0; i < 16; i++) {
Serial.print(tdata[i]);
if (i < 15) {
Serial.print(",");
}
else {
Serial.println();
}
}
