  • KEYWORDS: OneWire,1-Wire,DS18B20,Temperature

Module designed to server pull of DS18B20 1-Wire temperature sensors connected to Espruino pins.

Base usage.

var manager=require("OneWireTempManager").create([A0,new OneWire(A1)];
manager.start();

By default manager will print temperature values to console. You can setup custom callback:

/**
* @param {DS18B20} sensor
* @param {float} temp
*/ 
manager.callBack = function(sensor,temp) {
    console.log("Temp on " + sensor.sCode + ": " + temp);
};

Customizing DS18B20 instance.

You can customize any settings of the sensor (like resolution):

/**
 * @param {DS18B20} sensor
 */
manager.configureSensor = function(sensor){
    sensor.setRes(12);
};

Constants.

All constants should be modified before calling manager.start().

Constant Description
manager.C.SCAN_PERIOD 1-wire bus scan period. Default is 5 secons.
manager.C.POLL_PERIOD Temperature sensors poll period. Default is 1 second.
