    Not able to read Interrupt Status Register and reset Interrupts on MAX30102

    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...

    Opamp and photodiode. Try get to know where should be offset voltage?

    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...
