How to save data #1

Open diyahwidi opened 1 year ago

diyahwidi commented 1 year ago

Hello Alexandra,

Allow me to introduce myself, my name is Diyah. Currently, I am conducting research on detecting vital signs such as heart rate and respiration rate using FMCW Radar. I have read your thesis and published papers, and I have also tried the programs you provided on GitHub. However, I am facing issues during the program execution, where the saved data appears to be empty with no relevant results. I read in your thesis that we can extract FFT results from IWR-1843. Is it true that the output results stored in the .txt file are FFT results from IWR-1843?

I have attached the issue from the output of the program "data-collect-example.py," but the result is empty. Could you provide some advice or assistance regarding the issue I am encountering?

Thank you

Good Morning,

Thank you for your message and sorry for this late response ( I was in a 2-month holiday period with no access to e-mail and now I am finally at home). I confess that nowadays I'm not working with radars anymore but if you (still) need I can try to help. Everything that is in my thesis was working fine at that time (maybe some FW or SW updates could break something since then).

Tell me if you need help and I can review your e-mail better! Thank you for using my work.

Hello Alexandra,

Thank you for your response. After several attempts to fix your code, I have finally been able to retrieve data from IWR-1843, just as you did. I have also tried parsing the data using the code you provided on your GitHub account. However, there are a few things I need to clarify, and I would like to confirm my assumptions. So, from your code, which can be found at this link: https://github.com/alexandrasdl/RADAR-WORLD, it seems that you are using the configuration of AWR-1642. As far as I know, this configuration is for the vital sign driver module and not the out-of-the-box demo. Could you please confirm whether the data you collected and shared on GitHub and in your thesis document were obtained using the vital sign driver configuration? Because, to my knowledge, to run this configuration, we need to flash the hardware using a .bin file (the demo to be used), which implies that the vital sign driver, only available in AWR-1642, is not available in IWR-1843. Therefore, I would appreciate it if you could confirm whether you used the vital sign driver from AWR-1642 or if you modified it from the Out of Box demo to obtain the range profile.

Thank you in advance, and I hope you can read and respond to this email.

Best regards, Diyah

Hello again,

you are right! to make this code work, you need first to flash the IWR1843 with the Firmware code provided in "profile_VitalSigns for IWR1642" available at the texas website (not sure if it's available yet). At that time someone from texas told me that it could work due to some similarities between both IWRXX boards..I just had 6 months to develop my master thesis work and therefore I decided to use this hack just to accelerate the work. More, If my memory doesn't fail, that FW only activate 1 pair of tx/rx from the IWRXX boards, and therefore if you have time to explore it a little bit more, I think you could do really nice things with the mimo system of IWR1843.

Hello Again Alexandra, I have read the data from your thesis with title " Bio-Radar Applications for Remote Vital Signs Monitoring" and compared the data you shared on your GitHub account with this link : https://github.com/alexandrasdl/Thesis-Master. However, it seems that the data from the subjects you provided only has 3 subjects. Can I ask for the dataset you collected to help my research? I want to test the algorithm that I am currently developing, because the radar hardware we use is the same. Thank you in advance, I hope you will respond to this message

Best regards Diyah
