Product Number: MAX86150
I am recording data with MAX86150, the sample rate is set to 200sps for ECG and PPG. but when I record the data for each IC the sample rate is a number near 200 and it is not accurate.
this is the result:
recording time = 24:29:06 (HH:MM:SS) = 88146s
the desired samples based on the recording time = 88146 x 200 = 17629200 samples
but total samples generated by MAX86150 = 17645525 samples
real sample rate = 17,645,525 / 88,146 = 200.185 sample per second
this test with another MAX86150 IC results 199.45sps.
Has anyone else faced this problem? and is there any solution to solve this problem?
