No data in FIFO

[jupulidoplaz]

Hello,

I am working with the MAX 30105 to sense heartbeat. I have just set it up by specifying the led currents, sample average, led mode, sample rate, pulse width and adc range.

Then I clear fifo and then try to read its first value. However, reading the values of the FIFO and of the read and write pointers always gives me 0.

Is there something I am missing in order to get it to take samples?

Thank you,

Have you tried Example5_HeartRate or Example8_SP02?

Not sure I can help without seeing your code.
