1-wire DS18B20

[DiogenesSyndrome]

Hello,

I have gone through differents posts on the forum, but still did not found the answer for my specific DAQ.

I have a 6221 USB model and would like to read a 1-wire DS18B20 sensor. Is  there any code available for it ?

Please help... ;(

Best regards,

Hi,

You are using USB 6221 so you can only use Digital Input Signals for TTL digital logic levels. DS18B20 is a 1-Wire digital temperature sensor, you have to read the digital temperature from the 1 wire protocol of the DS18B20.

Have a look at:  Reading 1-Wire DS18B20 and DS18S20 Via a Serial or USB Adapter

Using cRIO or sbRIO

The following  should work as a generic example for implementing 1-wire protocol on the CompactRIO or Single-BoardRIO platforms.

For more informations please go to : 1-Wire Interface for cRIO and sbRIO - DS18B20 or DS18S20

I also thought so. Thanks a lot.

Hi, I know this is three years old but the link for the FPGA code is broken. Do you happen to have a copy of the project ?

Hi zmod,

it seems the code is lost in the "great reorganization", which happened in the community in the last months.

I already notified the moderators to help you to find that code example.

(You might search for "DS18B20" in the Code section of the community to find an article on "FPGA 1-wire interface". But even this article references missing code…)

Thanks. I spent a few hours last night trying to find it and searching without much luck.

Hi zmod_cz,

I apologize for the delay. The document with the example code you are referencing is a personal document that did not get migrated over. I'm currently working on getting the code for you.

I appreciate your patience and hope to get back to you soon.

Best Regards,

Hello Kristi,

Is it possible for you to share the VI for reading DS18B20 using sbRIO?

Thanks a lot
