Kelvshu,
We have developed reference design that has smaller form factor than the evaluation module (AFE4490SPO2EVM).
Here is the link for the pulse oximeter reference design using AFE4490.

Hello Royan, LED_DRV_SUP cannot be left floating in common anode configuration. You could use a separate supply to connect to the anode of the LEDs in common anode configuration. Figure 132 shows that you could also use the LED_DRV_SUP to connect to the…
Hello,
I have the AFE4490SPO2evm and I would like to work with it in MATLAB in order to get data in realtime and to do the data processing. How can I get the data from the AFE4490SPO2evm to MATLAB (I need the heart Pulse and therefore I need data from…
Other Parts Discussed in Thread: AFE4400 , MSP430F5529 Sir,
While building the sample codes using IAR or CCS an error is persistently coming ie "Error while running c/c++ compiler" along with some other file linking errors. And I do have a registered…
Hi Amy,
I have the AFE4490SPO2EVM board . The software provides me values for LED (Red) , LED(IR) , LED(Red)-LED(ambient Red) and LED(IR) - LED(ambient IR). Since I am new to this field, can you please guide me through the calculation to obtain the…
Other Parts Discussed in Thread: AFE4490SPO2EVM , AFE4490 Hi, I received the AFE4490SPO2EVM and also a "free" finger type oximeter sensor. I installed the software and the EVM is being detected properly. But when I try the oximeter sensor on my finger…
Hi Vitor Pinto,
I am also planning to design a reflective pulse oximeter using the afe4490. Is it possible for you to give me the design of the probe with the same photodiode. I am currently using the afe4490spo2evm board to learn the operation.
I…
Other Parts Discussed in Thread: AFE4490 Hello. I am a student at a high school and I am working on a project as part of my senior capstone project. The concept is relatively straightforward: we intend to use a pulse oximeter, using the TI AFE4490 evaluation…
The %SpO2 & HR Display tab cannot capture more than 2 minutes of data.
%SpO2 & HR algorithm implemented is not accurate. So we do not plan to support this mode of operation in the newer version of the GUI.
There is a newer version of the AFE4490 and…
Hello, I also wanted to ask, if there is any register that has a default value that I can read without having to make any other configuration, to see whether the communication is happening properly or not. For example, I have been checking the diagnostics…
