Part Number: AFE4490SPO2EVM Other Parts Discussed in Thread: AFE4490 , Tool/software: Hi, I am working on directly fetching ppg signals from AFE4490 using a dev board (without using AFE4490SPO2EVM) running on embedded linux via spi device "/dev/spidev0…
Aswath S said: Also, specifically I want to capture the ppg data via python without the usage of AFE44X0GUI. A serial communication between python script and the AFE eval kit.
How can we do this Praveen Aroul ?
Part Number: AFE4490SPO2EVM Hi Ti Team, I am trying to install the GUI for the AFE4490EMV board. However, I can't install the USB driver because the security signature has expired.
Could you provide me with the latest driver?
Best regards
Part Number: AFE4490SPO2EVM Hi Team,
I am using this simulator MS100 (rfmedical.com.br) to validate our algorithm written in python to find spo2 and HR. While the HR seems good, the spo2 value doesn't match the settings on the simulator. The simulator is…
Part Number: AFE4490SPO2EVM To my understanding, calculating SpO2 is given by the general formula of % SpO2 = 110 – 25 × R, where R = (ACrms of Red / DC of Red) / (ACrms of IR / DC of IR). I have been trying to figure out the SpO2 but have…
Part Number: AFE4490SPO2EVM Hi, I want to change the filter type from 'None' to 'Notch' but I don't see that option in my GUI (I'm in the ADC Configuration tab). Can you help me? Thanks!
Part Number: AFE4490SPO2EVM Other Parts Discussed in Thread: AFE4490 Hello,
I am currently working on acquiring the PPG (Photoplethysmogram) signal using Python code. Initially, I attempted to achieve this by setting a sampling frequency using timers from…
