Other Parts Discussed in Thread: AFE4404, AFE4403

Hi,

I'm developing the AFE4404 to work with SFH7050. I would like to find sample firmware for it, but there is none found. There is only for AFE4403 and 4400/4490.

Please if anyone can help, it would be very appreciated. Thank you very much.

Regards,

Nam,

There is some I2C interface sample code found on our product folder under tools & software.

A. What is the I2C slave address of AFE4404 board be default and how do we change it,if required.
B. Is there a descriptive sample code available where the AFE is interfaced with a MCU and all the parameters in the point number A are being computed and displayed.

Shortcoming with code given under "tools and software" (www.ti.com/.../toolssoftware)

1. Also it does not confirm that whether the data captured from AFE 4404 on I2C pins is PFR or any other parameter
2. It does not explain how to compute the values of HRM, HRV,Pulse Oximetry(Spo2), Vo2 and Calorie expenditure

regards

The I2C address is 0x58 and it cannot be changed. Found on page 6 of the datasheet

1. The data read is the register chosen by the user
2. Question #18 of our FAQ explains how to compute HR. e2e.ti.com/.../369445

For all of the other parameters, you can lookup the equations and implement it on your own.
