IWRL6432AOPEVM: Sample app/driver to get the data from the IWRL6432AOP sensor for the third party MCU

Bhavya Mathukiya

Part Number: IWRL6432AOPEVM
Other Parts Discussed in Thread: IWRL6432AOP, CC2340R5, , IWRL6432, IWRL6432BOOST, IWR6843ISK

Tool/software:

Hi TI Team,

I am planning to use the IWRL6432AOP with the Nordic's nRF54L15 MCU for the below mentioned use cases.

I want to get the occupied or unoccupied status from the sensor based on Motion/Micro Motion/Presence of a human
I want to get the distance of a person from the sensor.
I want to configure the detection range based on the room size.
I want to configure the zone inside the room for the human detection
I want to get the occupied and unoccupied status from the sensor based on zone configuration
I want to detect the pet
I want to get fall detection status
I want to get the gesture detection data from the sensor

I have few queries for above mentioned use cases:

Is there any sample app/driver for the Host MCU to communicate with IWRL6432AOP ?
Is there any single firmware for IWRL6432AOP which can achieve above mentioned functionality?
Through which interface Host MCU is able to communicate with IWRL6432AOP to get the Occupied/Unoccupied status, to configure range or zone etc.?

Best regards,

Bhavya

...All of this data can be decoded from the UART data coming off the device. See this guide for decoding it.

You can see a python example in the applications visualizer in the radar toolbox.

The motion and presence demo should be able to accomplish all.

Configuration and data processing happens through UART

You might also like using the CC2340R5 as the backend processor in this case for handling the data :).

Hi Nathan,

Thank you for your response.

Is there any sample application in C/C++ to parse the data frame coming off the device?
Is there any single chirp config file for the sensor to achieve my above mentioned features?

Bhavya

Hi,

I don't believe we have a C / C++ application readymade for this, but you can look in the tools/ or tools/visualizers/ folders of the radar toolbox.

The presence detect configuration would be a good starting point for your request here. You will need to modify it to support all your requests, but except for gesture, it should be able to do everything.

Hi Nathan Block,

From where can I get the mmWave Studio CLI for IWRL6432AOPEVM. The one in the radar_toolbox_3_00_00_05\tools\studio_cli is not for IWRL6432AOP as per its getting started guide.

Hi,

We may not offer Studio CLI for 6432. Why do you want to use it? Perhaps there is a different way we can get you the data you want?

Studio CLI is for raw data capture, which is not necessarily needed for getting up and started with the radar device.

Nate

Hi Nathan Block,

Here is my setup.

I want to achieve the use cases I mentioned at the start of this ticket. For that, I have to implement a parser application for my MCU for the data coming from the IWRL6432AOP. As you have mentioned earlier, there is no such sample code in C/C++, but the Python example in the applications visualizer can be taken as a reference. Meanwhile, I got to know about the Studio CLI, and I thought this tool could be used to receive UART data from the sensor, and give the processed output (i.e., Occupied, Unoccupied, Object distance, etc.) in textual form instead of GUI-based. So, do you have anything like this that can help me here?

Hi Bhavya,

Studio is designed to stream the raw ADC data from the radar to another processor. You don't want the raw ADC data (based off above where you ask for the occupied/unoccupied status, object distance...etc). If you use studio to stream the raw ADC data, then your companion processor will need to run all the radar processing on the ADC data to reconstruct the scene. I would highly recommend mimicking the python code in the applications visualizer. It is quite straightforward. You could start with the following functions.

File	Function	Description
gui_parser.py	readAndParseUartSingleCOMPort	readAndParseUartSingleCOMPort reads the UART data coming from the IWRL6432 to the computer. It awaits for the magicByte sequence (0x0102,0x0304,0x0506,0x0708) to begin processing
parseFrame.py	parseStandardFrame	parseStandardFrame parses the frame Header (version, packet length, platform…. Subframe Number)
parseFrame.py	tlvheaderDecode	tlvheaderDecode extracts the Type and Length for each TLV
parseFrame.py	parserFunctions	parserFunctions is not technically a function, but a list that maps the TLV Type to the processing function to decode the TLV value. Each of these parser functions can serve as a template for decoding the TLV you will eventually send. For example, the parseRangeProfileTLV() function shows how to parse the range profile data.

Hi Nathan Block,

Yes these are the files and functions I have already gone through before when you suggested and I understood I have to implement these logic in C for my MCU. Meanwhile I was searching if TI is having any CLI based or textual tool which gives final outcome (like Occupied, Unoccupied, Range, Zone config etc.) after parsing data getting from sensor over UART. As at the end in final product GUI is not being used. But it seems like as of now GUI based visualizer is the only option. Generally how other customers are using this sensor to make MCU based final product?

Hi Bhavya,

The easiest way to do this would be to remove the GUI code from the demo. If you use the functions above, you can get a lightweight python script that stores all the variables in a python dictionary. This is the most complete version we have available for what you're requesting.

Hi Nathan Block,

Can you please confirm whether the fall detection and gesture detection is supported on IWRL6432AOP. If yes, can you please provide or point out the link for the firmware of IWRL6432AOP and .cfg file? I got this reference for gesture https://dev.ti.com/tirex/explore/node?node=A__ASEw.q0HwWKS3JBxoaLGog__radar_toolbox__1AslXXD__LATEST and for fall detection https://dev.ti.com/tirex/explore/node?node=A__ASLYqCsRSJ1u0QgkBzERNA__radar_toolbox__1AslXXD__LATEST but it seems not for the iWRL6432AOP.

Hi,

We do offer gesture for 6432, but not the 6432AOP at the link you provided. We do not offer fall detection on the 6432 platform now, though you may develop your own solution based off the point cloud/heatmaps/tracker data.

Best,

Nate

Thank you for the clarification. I understand that developing our solution will extend our time to market. Could you kindly suggest a suitable platform that includes sample firmware and .cfg from TI to support the following use cases?

Room-wise occupancy detection
Zone-wise occupancy detection (zones inside a room)
Room size configuration
Zone size configuration
Fall detection
Gesture detection
Pet detection (differentiating between human and pet for occupancy decisions)

BR,

Our MPD demo supports these (out of box demo for 6432)

Bhavya Mathukiya said:
Room size configuration

Zone size configuration

I don't know what this is asking. You can manually configure the room size and zone size in th econfiguration file using the MPD demo.

Bhavya Mathukiya said:
Fall detection

This is not supported on 6432 for now, but it is supported in the 3D people tracking offering for 6843

Bhavya Mathukiya said:
Gesture detection

We have demos for this on 6432 and 6843 right now on tirex.

Bhavya Mathukiya said:

We have a human vs non-human classifier on the MPD demo 6432 now.

1. What is tirex? and does the demos for 6432 work fine for 6432AOP ?

Moreover if I want to fulfill my all above mentioned use cases, which SoC do you recommend as 6432AOP is not having support for fall detection and I think firmware for gesture for 6432AOP is also not there in radar_toolbox_3_00_00_05.

Even I have tried with xwrl6432_gesture_recognition_demo.Release.appimage but not able to detect any gesture.

My apologies - tirex is the site found here : https://dev.ti.com/tirex/explore/node?a=1AslXXD__3.00.00.05&node=A__AEIJm0rwIeU.2P1OBWwlaA__radar_toolbox__1AslXXD__3.00.00.05

I believe gesture is the only demo supported on 6432 but not 6432AOP. The MPD demo exists for both devices.

You can use the iwr6843isk if you need an out-of-box fall detection demo, or you can use the iwrl6432boost if you want lower power consumption and you can develop your own fall detection demo.
