I have Arduino mega and Lego temperature sensor which I would like to connect to the Arduino. I'm trying to use a I2C connection between them, with no luck. I connected the sensor and Arduino referring to the picture below:
I'm using the Wire library for transmitting data. This is my code currently:
#include < Wire.h >
byte ADDRESS=0x98;
byte CONFIG=0x01;
void setup(){
Serial.begin(9600);
Wire.begin();
Wire.beginTransmission(ADDRESS);
Wire.write(CONFIG);
Wire.endTransmission();
delay(100);
}
void loop(){
Wire.beginTransmission(ADDRESS);
Wire.write(CONFIG);
Wire.endTransmission();
Wire.requestFrom(ADDRESS,2);
delay(100);
int avail=Wire.available();
Serial.println(avail);
delay(100);
}
#include < Wire.h >
byte ADDRESS=0x98;
byte CONFIG=0x01;
void setup(){
Serial.begin(9600);
Wire.begin();
Wire.beginTransmission(ADDRESS);
Wire.write(CONFIG);
Wire.endTransmission();
delay(100);
}
void loop(){
Wire.beginTransmission(ADDRESS);
Wire.write(CONFIG);
Wire.endTransmission();
Wire.requestFrom(ADDRESS,2);
delay(100);
int avail=Wire.available();
Serial.println(avail);
delay(100);
}
I found the config and address values from RobotC drivers for the same sensor. But all I get is zeros. Is there any way i could check for a defect sensor? Is my code correct?
