Other Parts Discussed in Thread: DCA1000EVM
Hello,
I am assisting one of our customers as they evaluate the IWR1642 eval board from TI. They had the following questions, sorry it's a long list but hopefully some of them are easy answers. Let me know if you have any questions, I can be contacted via email if so:
1. The overall goal of our current experiments is to pull the raw data off of the sensor for analysis via an external program to evaluate the radar. Is this possible ? What is the best way to extract the data?
2. Has TI experienced any IC over heating issues when trying to use more memory or increase # of chirps over UART? We increased the chirps and the card stopped working (and got very hot) and is now DOA.
3. Why in the Vital Sign Demo only 2 chirps are collected and only one is processed? Does it take too much time to compute heart rate and respiration from more chirps per frame to improve SNR?
4. Why is there a limitation in the Frame duration (~30 msec) in the Demo? Is just for the Demo or a general guideline?
5. What would be the best way to collect just the fft of the chirps (no processing for heart rate and respiration) and what would be the max rate of chirp we can collect?
6. Can we go above 1Mbps transfer rate from UART?
7. What are the advantages/disadvantages to using more than one antenna ?
Thank you!
