Hi there!
I am currently having some problems measuring PPG and Spo2 using the AFE9450EVM development board.
As shown in the figure, this is how I configured the red LED and IR LED, as well as the PD related parameters. The purpose is how to configure some parameters that can be plotted in the figure for each of the two channels so that I can (using the AC and DC values measured by the two channels) calculate Spo2.
I look forward to your answer.
