Hello,
We want to develop a frequency strength detector using awrl1432 to detect a 77Ghz signal coming from another cars.
When I checked exmaples here, I think there doesn't seems to have an example of this kind of stuff. Could you recommend an best example code for our target system?
And I have some questions on SW for AWRL1432.
I'd like to check the approximate amount of the scope that can be modified by SW.
Could you check our questions below?
- Is it possible to adjust the Chirp frequency range?
If yes, could you advise how to change it?
- Is it possible to adjust the Chirp period or cycle?
- Is it possible to adjust the number of ADC buffers and sample frequency of each Chirp?
- When I look at your examples, most of them seem to use saw-tooth wave chirp. Right?
Any other chirp could be implemeted?
- Do you support Both realFFT or ComplexFFT, so can I slect one of them?
- What kind of window-functions are provided? Chebishev or Keiser is provided?
- Does your sw support SlidingDFT?
Thanks in advance for your reply.
Regards
KS
Hi KS,
While we do not offer an example that supports your exact application, you can use the out of box demo to get started.
It can be found here
C:\ti\MMWAVE_L_SDK_05_03_00_02\examples\mmw_demo\mmwave_demo
The Chirp frequency range, Chirp period, number of ADC samples and mode of operation can be changed by modifying the profile configuration. More information about the profile cfg for the mmwave out of box demo can be found here
