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

  • Hi,

    Unfortunately I cant help with the code but I'll try to help with the setup:

    First, have you setup the GPIO pins of the SDP board?

    Figures 11 and 13 of the UG-255 will help this explanation:

    Since this is a multiDAC board, there are different SYNC lines.

    The AD8403 uses SYNC1, set up GPIO pins 5, 6, 7 to be outputs at logic 0. This selects S0 (SYNC1) on the Mux.

    The AD8403 also uses /SHDN and /RESET, set up GPIO1 and GPIO3 to be outputs at logic 1.

    If you have done this already or if you still experience issues, please let me know.

    Regards,

    David
