AWR1642: How to verify my mmwave studio's configuration is right?

rongjiang liu

Part Number: AWR1642

Assume i have config a awr1642 EVM by using mmwave studio, How can i verify my mmwave studio's configuration is right?

someone tells me save config as XML file, an then code a matlab script to read the XML file. But i think this method just reappear my config.

If i cannot know the studio, cannot understand studio, cannot recognize the studio, i will not be sure whether my studio's config is right.

If there is a method which can plot the frame construction and the chirp figure according my configuration, i can judge the construction and the figure is the frame and the chirp what i want.

Hi,

One way to check a chirp configuration is to use the mmwave sensing estimator.

Please check the mmwave sensing estimator training

training.ti.com/mmwave-sensing-estimator-overview

Thank you
Cesar

Hi, Cesar.
i do not mean how to estimate the parameter.
i mean to verify the frame structure is what i want, like the number of sbuframe, burst and chirp, like the loop of sbuframe, burst and chirp.
i want to check the frame structure which the congfiguration sets in the studio is the right frame structure i expect.
If there is a method which can plot the frame structure and the chirp's figure according to studio's configuration?

Hi,

Unfortunately there is no such tool to plot the configuration. Do you have any specific questions on using Advance frame configuration API?

oh, i think ti should better provide such plot function.

I have other question in other thread. i confused with the result of forceprofile=0 or 1.
Anand answer me, but i cannot under his answer, and i still find where i am wrong for fig3 and fig4.
Would you please take a look at the thread e2e.ti.com/.../2630841

Also i am confused how to config BPM mode frame, and later i will put thread.

Anyway thank you very very much.

Hi Lin,

I guess the problem seems to be that you intend to use non continuous Chirp Indexs to create a burst which is not possible.

For your configuraiton that you intend to achieve
C1/C3/C5/C7/C9/C11/…../C511 belongs to Profile1, and the ids are 0/2/4/6/…/510.
C2/C4/C6/C8/C10/C10/…/C512 belongs to Profile3, and the ids are 1/3/5/7/…/511

I would suggest define,
C1/C3/C5/C7/C9/C11/…../C511 belongs to Profile1, and the ids are 0/1/3/…/255.
C2/C4/C6/C8/C10/C10/…/C512 belongs to Profile3, and the ids are 256/257/258/259/…/511

Now you use Advance Frame configuration to define how you want these sequence to repeat over time in 2 sub frames.

Kaushal
