Tool/software:
Hello, I have one question. I was originally used as differential mode, but there are cases that I need to measure the heart rate with one hand.
In the circuit, after removing R158, R163 from the HW point, it was tested by mounting a 0 ohm resistance instead of C228.
However, I don't understand when I checked the value.
1. From HW, I wonder if the filter value is correct when using single-ended mode.
In the differential mode filter, I left the negative channel as it is and only changed the positive to the analog GND, is there anything that should change the filter value?
2. I would like to ask if there is any firmware or config modification when changing from differential mode to single-ended mode.
I'll be waiting for the reply. Thank you.
