Hi,
I'm part of a computer science research team at a university and we're working with an existing device that uses the AFE4405 for PPG measurements. The raw output we're seeing from the device is a list of 16 floats, all but the first 4 of which are 0s, in the ~10^-30 range.
These are not the typical values we're accustomed to with PPG data but we're having a hard time tracking down specs that describe the data since grabbing raw PPG values from the device we're using is not supported.
Our questions:
1) What do the 16 values represent? (Are these from the AFE4405, or generated by the intermediate device?)
2) What are the 4 float values that seem to represent actually PPG sensor output? We're used to seeing 1-2 values per reading (red and/or green values).
Any guidance is much appreciated!
Thanks,
Erik
