![]() I have written these two codes, they somewhat do what I expected but the result isn't consistent. Datatype 1 are integers and datatype 2 are chars. I want to sent two different types of data on two different I2C addresses. Serial.I have a master-slave setup consisting of a nodeMCU(master) and an arduino nano(slave). Void printTemperature(DeviceAddress deviceAddress)įloat tempC = sensors. Void printAddress(DeviceAddress deviceAddress) Pass our oneWire reference to Dallas Temperature. Setup a oneWire instance to communicate with any OneWire devices #include // Data wire is plugged into port 2 on the Arduino ![]() It is recommended that you connect only one sensor at a time so that you can find each sensor’s address and assign it a name. The sketch below detects all DS18B20s on the bus and prints their one-wire addresses on the serial monitor. Finding the Addresses of DS18B20s on a Bus So we’ll use one sketch to find and record the address of each sensor, and then another sketch to read each sensor individually. print(DallasTemperature:: toFahrenheit(tempC)) Įach DS18B20 is programmed with a unique 64-bit address at the time of manufacture, allowing them to be distinguished from one another. print(( char) 176) //shows degrees character Display temperature from each sensor for ( int i = 0 i < deviceCount i++) Send command to all the sensors for temperature conversion Pass oneWire reference to DallasTemperature library Setup a oneWire instance to communicate with any OneWire device #include // Data wire is plugged into digital pin 2 on the Arduino
