AFE4404 Setting

Other Parts Discussed in Thread: AFE4404, AFE4900

Hi I am AFE4404 using development.

As you can see in the picture, I'm done turning on the LED.

Now I need to get PPG data, but I don't know the REG ADDRESS value.

When I was using the AFE4900, I got it using 0xFF as FIFO, but I don't know because there's no FIFO for the AFE4404.

Help me.

Thank you.

    Hello Kim,

    In AFE4404, the ADC output codes are available in register addresses 0x2A through 0x2F. 

    If decimation is enabled, then the decimated data will be available in register address 0x3F and 0x40.

    Please refer to the AFE4404 datasheet for additional details.
