    Davy,


    I'm sorry, but I'm not sure I understand the question. It looks like there are you are using two ADS1241s and you get different data from each reading the same thing?

    I suspect this is some sort of communication problem. However, to help debug your problem I'll need more information about everything in the system. I need a detailed description of the problem in the readout. If the data is bad, then I would need to know the expected result and bad result. If there are cases where the data is good for both devices, I need to know if there are any differences in the read method.

    Also I would need to know the timing of how each device starts a command and the timing for the readout. Scope shots or an output of a logic analyzer would be very helpful in debugging this type of problem. A schematic for the circuit might also give more detail to the solution.

    Regardless, start with a detailed description of the problem, and we can try to debug it.

    Davy,


    I haven't gotten a reply from you about your data problem. I've given a couple of things to consider, and I hope you've gotten the correct data out. I'll close out this post for now, but if you are still having problems, feel free to post back to reopen the thread.
