I am currently trying to develop a pulse oximeter. For this I use the MAX30102 sensor and the NXP LPC1768 microcontroller. The communication is done via I2C.
I have configured the MAX30102 sensor to generate an interrupt as soon as the FIFO is full.
As soon as I start the program in debug...
Hi,
I created simple circuit with photodiode for pulse oximeter. As you can see I use opamp in single supply mode. After removing DC offset I put 1V offset on non-inverting input on opamp. Then RC filter is connected to grond. Is everyting correct?
I wonder if I should connect REF on ADC to...
