DS18B20 reading
Posted: Wed Apr 27, 2016 2:49 pmHi,
When reading more sensors in basic program and only one sensor (or no sensor) is connected basic show readings from other sensor
when You connect only one sensor you get same temperature on curr, curs, curt variable
so i made simple change (maybe this is bad change but it works for me)
I also add next parametr which set resolution of DS18B20 reading. For this You must declare variable tempDeviceAddress with

Code: Select all
temp 0 curr
temp 1 curs
temp 2 curtwhen You connect only one sensor you get same temperature on curr, curs, curt variable

Code: Select all
if ( Param0 == "temp" | Param0 == "ti")
{
valParam1 = GetMeThatVar(Param1).toInt();
valParam3 = GetMeThatVar(Param3).toInt();
if(sensors.getAddress(tempDeviceAddress, valParam1)) {
if( valParam3 >= 9 && valParam3 <= 12 ) {
sensors.setResolution(tempDeviceAddress, valParam3);
}
sensors.requestTemperatures();
SetMeThatVar(Param2, String(sensors.getTempC(tempDeviceAddress)));
}
else
{
SetMeThatVar(Param2, String(F("No sensor")));
}
return;
