Arduino and Dallas DS1820 (one-wire)

[BrewJoe]

So I was able to get the onewire to work. Now i am trying to figure out how to get more that just one to work within the loop. Is this possible within labview? I tryed creating two cases within the .ino files but only one works. Please help. thank you

okay I just went over post 159. The one issue with me using that is I need to be able to see both temps at one time. and then be able to link set temps to actions such as right to an SSR.

Hi.

I downloaded your code but i have problem.

I catch an error because don't have DattasTemperature.h.

Downloaded it from internet but i have other problem:

Can you help me?

Thanks

P.S. Sorry for my improbable english 🙂

Hi Mikcondo,

About your problem: I assume you need to add the DallasTemperaturelibrary to arduino your library folder.

On another note:

LIFA was replaced with LINX about a year ago.  LINX provides all the same functionality as LIFA and includes a lot more features, like more supported devices, more build in sensors and a firmware wizard to upload the firmware for you, so you don't run into issues like the one you're seeing (its probably because the arduino API changed something in the latest build).

Check out LINX and let us know if you have any questions as you get started.

More info on using DS sensors with LINX can be found (for example) here

Hello, since no library one wire sensor for LINX, you can try this procedure I found on this site,  I hope someone can post figure out the LINX code, http://www.instructables.com/id/Arduino-Labview-With-2-DS18B20/?ALLSTEPS

You can add support for the sensor using LINX Custom Commands, FYI.

For Linx, a custom code supporting up to four Dallas DS1820 sensors HAS been developed too (by me ), see

Hi everyone,

I tryied some hours to add the command for a ds18b20 sensor to the original LIFA for Arduino. I used the code written in te Posts 5 and 6 of this thread. But I'm unable to read the Temperature in Labview. My Goal is to measure the Temperature with an DS18B20, then send it with Arduino to Labview and control a relais over a digital output of the Arduino.

I red this thread a couple of times but the most part of the posts are quite old and for older Versions of Labview/Arduino and I'm still unable to implement it.

Thanks for your help!
