Hi Ti teams,

According to the Hardware spec. & register setting  of ADS1298R, the waveform of respiratory isADS1298R respiration issue.docxADS1298R respiration issue.docxn’t displayed.

The attached file is Hardware circuit diagram & the register settings as followed:

ADS1298R

16h:0xF6

17h:0x22

How can we set the register or revise the hardware to fix respiratory waveform issue ?ADS1298R respiration issue.docx

    Hi Jam,

    Thanks for the post.

    The respiration schematic looks fine. Are you testing the respiration with a patience simulator? Can you also provide the full device register settings for our reference? Is it possible for you to bypass the two analog switches in the respiration path for testing purposes?

    Thanks.

    0x02        0x10
    0x03        0xCC
    0x04        0xEF
    0x05        0x40
    0x06        0x40
    0x07        0x40
    0x08        0x40
