1-wire Labview drivers

[cmdrb]

hi VADave,

Can i use it using labview 8.6?

it seems its looking for FPGA I/0 stuffs.

You will have to recompile everything for labVIEW 8.6.  You will have to change the FPGA target to match your FPGA target.  Once that is done everything should work.

Hi,

I think i may need some expertise on this. Im not familiar FPGA.

thanks

I have developed code to operate the following 1-wire devices

DS2406

DS2450

DS2413

DS2408

DS2438

I got started with the help of code that I found on the NI site for the temperature devices

DS 18B20

DS 18S20

I have also developed code to operate the 1-wire AAG TAI-8540 humidity device – which use a DS2438

I am currently trying to develop code for the 1-wire AAG TAI 8570 pressure sensor device – which uses 2 x DS2406 – although I am not sure exactly how. Has anyone had any success with this one?

Hello,

I would like very much having an example with DS2438.

I tried with :

http://decibel.ni.com/content/docs/DOC-1092

modified for the 2438, but I do not get the bytes of page 0 as the DS2438 should return after a command BEh00h.

Yet it communicates, it returns its identifier properly.

Here are the VIs are used for a DS2438. I used this for two different 1-wire Humidity sensors.

Hi NeilJohn,  thank you for the answer.

Regrettably, the sub VI Read DS2438 NJB.vi that contains probably the information which I miss is not included in your

1-wire DS2438 Controller via DS9490 USBBridge new.vi

Stephen.

Sorry about that I wrongly assumed the VIs used by the main VI would be sent as well. Here are the VIs that I think you'll need to run the VI I sent. It looks like I can only send three at a time.

[NeilJohn]

Here's three more

[NeilJohn]

And the final three VI - I think.
