Dear forum,
I'm new to arduino and this is my first topic here.
I have question about dallas 1-wire temperature sensors. I have code where i am reading 4 this DS1820 chips and displaying valuses with time stamps on serial monitor and lcd and also i am logging these data to SD card.
Everithing works OK mainly thanks to all great guys from several forums. Many thanks to them.
My only problem is that when i get temperature from DS1820 it is in format 19.25°C but i need 19,25°C. So i need decimal separator with comma not a dot ! ! !
Is this possible to fix this i my code or library, I need this because the other program I am using to analyze these data. And i trully need t fix this, so please guys hep me :~
Here is the coede:
// libraries
#include <Wire.h>
#include "RTClib.h"
#include <OneWire.h>

// DS18B20 sensors on I/O pin 9
#define ONE_WIRE_BUS 9
OneWire oneWire(ONE_WIRE_BUS);
DallasTemperature sensors(&oneWire);
// Assign the addresses of your 1-Wire temp sensors.
