Hello All,
I understand that the ADPD4100/ADPD4000 configuration must be defined for each use-case.
I am using ADPD4100 for a wrist worn heart rate estimation application.
what is the basic configuration for this?
Meanwhile, I am sharing the ADPD4000 PPG measurement config file. For ADPD4100, please contact me.
