Dallas Temp failure to compile

[tlpeter]

Thanks, that works fine.
How come that i have an old library? i use the 2.0.0 version
Is this perhaps a known issue which will be fixed soon?

It's not related to mysensors core library.

Also, as mentioned before in this thread, the Dallas library that is in the arduino examples repository, is working.

Are you sure that you are using the right libraries?

[tlpeter]

I tihnk so, i used libraries that i was pointed too as they are moved.
All other sensors i have been playing with are working fine.

@tlpeter it is because now the libraries which are not managed by MySensors project were moved to another repository. It means if you only updated MySensors, you kept the old libraries.

[tlpeter]

I removed everything and started from scratch and after that i copied the mysensors-master library.

"removed everything" in MySensors directory ? That's not enough, as the third party libraries are in the libraries directory of Arduino

[tlpeter]

I uninstalled that too.
I really removed everything.
Uninstalled arduino and removed the folders in the program files folder and the my documents folder too.

why not put the function millisToWaitForConversion into the example.
I like to have the latest libary available for sensors. It can be loaded with the arduino studio.
Read the min wait time is pretty easy. it is just a switch case based on the datasheet.

// returns number of milliseconds to wait till conversion is complete (based on IC datasheet)
int16_t DallasTemperature::millisToWaitForConversion(uint8_t bitResolution)
{
    switch (bitResolution)
    {
    case 9:
        return 94;
    case 10:
        return 188;
    case 11:
        return 375;
    default:
        return 750;
    }
}

Ok, so you are using a newer version of the DallasTemperature library, than the one that we have supplied in our MySensorsArduinoExamples. And yes, it seems that they have made millisToWaitForConversion() a private function there. Or someone has changed the library we included in our repository at some point in time, so it is made public.

There are 2 options, as I see it :)

1. Use the library that we have supplied in MySensorsArduinoExamples
2. Make a PR against the original library, found here, and make the millisToWaitForConversion() public, and get them to release a new version of the library.

:)

The millisToWaitForConversion has always been private in milesburton's library, so the answer is the latter: someone has changed the library we included in our repository at some point in time.

I found the answer in git:

commit e47e596075282b122ac5d266ec6ad5c60ca8c978

    Make DallasTemperature::millisToWaitForConversion() publicly available

I agree with tbowmo's options.

[robosensor]

It's my code :scream:

I changed this method from private to public, this function is used to determine wait time needed for right non-blocking wait call. Seems like I should make PR to original library instead of modifying MYS copy.
