    Dear Support,
    

    I'm using with success the CN0428 Water Quality Measurement System with your evaluation software: it's great!
    

    Now, for the project I'm developing I will prefer the AD5940 component to be used with a companion MCU. I've downloaded from your ftp server the examples pack related to the EVAL-AD5940ELCZ, they are very easy to understand and to implement, but  I have not been able to find any example regarding the measurement of pH and conductivity, although the BNC suitable for this is present on the board.
    

    Now, since the porting of your examples from ADuCM355 (CN0428) to the EVAL-AD5940ELCZ is not so fast, I wonder if you can provide me with the example code to carry out these measurements on the EVAL-AD5940ELCZ board in an easy and fast way to validate the product.
    

    

    Regards,
    

    Stefano T

      Hi Stefano,
      

      Thank you for you query. Our latest examples for the AD5940 are located on GitHub.Unfortunately we do not currently have example projects available specifically for pH and conductivity measurements. However we do have a number of application level and block level examples that can be used and modified to carry out pH and conductivity measurements. In the mean time ADI will work to develop custom examples and add them to the SDK.

        Hello MLambe, 
        

        

        I will be working on an ad5941 which will be a companion chip to an MCU.
I'm going to use this AD5941 to do a conductivity measurement, I can't find an example in the git repo.

Have you developed an example of conductivity measurement or would you have an example to provide me?

        Regards, 

        RPaul
