Other Parts Discussed in Thread: IWRL6432
Tool/software:
Hi Experts,
I am dealing with the level sensing application using IWRL6432 AOP. Below are what I have done:
- I followed the steps in the level sensing user guide, using the IWRL6432 AOP device.
- The prebuilt FW is fine and with the default configuration “high_accuracy_demo_xwrl64xx” the sensor is running well. The results can be shown in the industrial visualizer.
high_accuracy_demo_xwrl64xx.cfg
- Then, I saw the maximum adc sample number is 1024, and I try to adapt this from the default configurations. Attached is the configuration from me “high_accuracy_demo_xwrl64xx_chia”.
high_accuracy_demo_xwrl64xx_chia.cfg
- Different to the default configuration “high_accuracy_demo_xwrl64xx”, I enlarge the adc sample number from 512 to 1024, but it shows error of -3110.
- I investigate this in the mmw_error.h and mmwave.h and find that it is the problem of frame configurations, so I enlarge the frame timing and decrease the antenna FFT size in sigProcChainCfg. After this the error of -3110 is gone.
- Fortunately, I am able to have the output results of this configurations, but it still shows errors in the visualizer.
My questions are:
- Since the configuration is okay, where does this error come from? How can I solve it?
- I would like to confirm that the maximum detected range of 30 meters in the configuration “high_accuracy_demo_xwrl64xx_chia“. Since 1024 points of adc is the maximum number, and I would like to have 30 meters of detected range, does that mean the largest BW is limited to 2 GHz in this configuration?
Thanks!
Best regards,
