Problem for finding complete working code and connection of AD5934 IC with Arduino uno

I have tried in all possible ways

What is the state of your project at this point besides its urgency? Do you have your Uno board connected to your PC? If so, can you load and execute any (AD5934 unrelated) demo sketch with it? If so, can you hook up your AD5934 chip (pinout is identical to the AD5933 shown) to your Uno according to the diagram:

?

If you have done that, can you Copy/Paste the code form Antonius's AD5934-Arduino-Driver link into your environment, compile and execute it? If not, what would be the holdup?

Hi,

https://github.com/mjmeli/arduino-ad5933

I have complied this code and checked...

It is not working with interfacing with Arduino...

Dont know the reason ..

could you please suggest me ..

Hi,

I am connecting AD5933 Evaluation Board with Arduino UNO can you please send the available code links and all

I do not think it is an easy task connecting the Evaluation Board to Uno. The Evaluation Board is designed to work with Windows PCs. You would need to solder the I2C wires to the board to use Uno's interface, at which point it might be more straightforward to do that with a bare AD5933 chip instead.

Hi,

I have solidered the I2C pins and connecting to uno....

Here,VDD-EXT pin of evaluation board can we give 3.3v power supply 

Good luck with your effort.

Thank you

Hi,

Is the coding reference link will even work with the evaluation board

Hi,

Can you please share the code where RFB and Zunknown is connected and the impedance of Zunknown should be displayed on Serial monitor ................please any one can suggest me

It is a bit more complicated than that: one has to calibrate the system first and then Zunknown is calculated based on the calibration data. It is usually done by connecting a resistor of a well-known resistance - Rcal, measuring system output - Out, based on the two values calculating system gain: from Out = Gain / Rcal  =>  Gain = Out * Rcal  and storing the value of Gain. Then connecting Zunknown, measuring Outunknown and calculating Zunknown = Gain / Outunknown.

In terms of the code, the closest to what you seem to need is the code for CN-0349, The CN-0349 board has the calibration resistors and switches that connect/disconnect those resistors and unknown impedance to/from the measurement circuit, so, since you would need to do that manually - the code needs to be modified accordingly.
