Other Parts Discussed in Thread: AWR1642
Hello,
We are currently working with the AWR1843 radar module for object detection using Raspberry Pi.
We generated a config file from mmWave Demo Visualizer for the radar with 2 transmitter and 4 receivers .
We are reading the collected data serially radar on Raspberry Pi after sending the mentioned configuration file for further processing
Following are a few queries/doubts we would like you to help us with:
1. While sending the configuration and reading the detected objects, we came across the term "Magic Number". We would like to know what exactly is it because, this number seems to change sometimes.
2. In the image below, we came across a field called "Descriptor" in the detected objects area. While referring to the "C:\ti\mmwave_sdk_03_01_00_02\packages\ti\demo\xwr18xx\mmw\docs\doxygen\html\index,html" file, in the "MmwDemo_transmitProcessedOutput" function we could not find any reference to the descriptor. It looks like the descriptor is no more valid in the newest sdk. Kindly let us know about it.
3. As we can see in the attached figure, the header has a total of 40 bytes(36 + 4 bytes for sub-frame as referred to index.html file).
Suppose we detect 4 objects, the results are fine. The calculations are as follows:
Data buffer = Header(40 bytes) + Detected Objects(Tag and Length)(8 bytes) + Payload(4*16), where 4 - # of objects detected.
Data buffer = 112 bytes < 128 bytes (works fine in this case)
If the # of objects detected is >5, Data buffer >128 and it gives an error.
We would like to know why does this happen or are we missing anything.
5. We are using the attached file for Demo Data Structure v0.1 for AWR1642 as a reference. Is there a similar document for AWR1843 or does it follow the same format.
