AD8403 - SDPAPI interface

Hi

 

I am trying to communicate to the AD8403 Evaluation board via SDP-B platform. I have received an evaluation software with the board which works fine. I would like to communicate to the board via VB.net script and hence I am using the sdpapi1.dll which comes with the software. However I am not able to the connect to the board because the sdp needs a unique ID to identify the daughter board connected to the SDP. Can anyone please help me with the ID.

 

Thank you

    I am able to set values to RDAC1. At 0 and 255(FF) Wiper1 changes resistance as expected. How do I set values to RDAC2, RDAC3 and RDAC4.

    As per the data sheet, AD8403 chip will read the 10bit data. 1st 2 bits are address and next 8 bits are wiper position. The programming interface only allows to send 8 bit data. I am not sure how to set the address to change values of RDAC2,3,4.

    Kind Regards
