HELLO,

i want to know what is the interfacing address of MAXREFDES 117 or we can say i2cTransaction.slaveAddress.

there is two type of slave address one for read (0xAF) and other for write (0XAE). but in the interfacing of the board i required the i2c address.

plz give any suggestion to my problem .

Thanks

Hello Kalpesh,
You need to find the sensor data sheet to find the sensor address.

"The MAX30102 slave ID consists of seven fixed bits, B7–B1 (set to 0b1010111)."

Hello Kalpesh,
For the sensor controller you can review the "Button Debouncer for LaunchPad" example.

For using the TI-RTOS pin driver you can look at the pinInterrupt example:

Hello Kalpesh,
I believe you will have to port the maxim_heart_rate_and_oxygen_saturation function from algorithm.cpp found here:
github.com/.../algorithm.cpp

We are not familiar with the external algorithm.cpp file and the MaximIntegratedRefDesTeam githib project. For more details on the specific implementation you can also consider to post a questions in other related forums.
Hope it helps.
