Hello,
I'm trying to read the temperature without success with the bellow code :
Serial.println("Scanning...");
byte error, address;
nDevices = 0;
for(address = 1; address < 127; address++ ) {
Wire.beginTransmission(address);
error = Wire.endTransmission();
if (error == 0) {
Serial.print("I2C device found at address 0x");
if (address<16) Serial.print("0");
Serial.println(address,HEX);
addr = address;
nDevices++;
} else if (error==4) {
Serial.print("Unknow error at address 0x");
if (address<16) Serial.print("0");
Serial.println(address,HEX);
}
}
Log :
11:07:07.672 -> Scanning...
11:07:07.672 -> I2C device found at address 0x4A
As I can see the temperature module has been detected with the address 0x4A.
uint16_t addr = 0x4A;
Wire.beginTransmission(addr);
Wire.write(0);
Wire.endTransmission(false);
Wire.requestFrom(addr, 2);
byte h = Wire.read();
byte l = Wire.read();
Serial.println( h);
Serial.println( l);
Log :
11:21:45.051 -> 0
11:21:45.051 -> 0
Somebody is able to help me ?
May be the wrong part is «Wire.write(0); » .... not sure to understood correctly the datasheet
Thanks in advance for your help.
