    I can desing the ads1298 Register function to Impedance Meter desing?

    Example product : MODEL 1089 MK III  CHECKTRODE® 

    Various readings indicate the following:
    5 K or less – excellent skin prep: proceed
    with recording and expect good results.
    5 – 10 K -- good skin prep, but expect
    some noise in the recording.
    10 – 30 K -- fair skin prep. Contact
    impedance may decrease with time, but for
    best recording quality, electrodes should be
    removed and skin re-prepped.
    Above 30 K -- bad skin prep. Even slight
    patient motion will cause. Electrodes must
    be removed and skin re-prepped.

      I have no idea, because this is the MSP430 forum and not the ADC forum.

      However, I'd guess the answer is 'no', since ADCs usually meter voltages, and no impedances. So at least some external circuitry and some math (or even more and more complex circuitry) would be required.
