IWR6843ISK: Need Help From Scratch

Shidhin Varghese Philip
Prodigy 10 points
Part Number: IWR6843ISK
Other Parts Discussed in Thread: IWR6843, MMWAVEICBOOST, IWRL6432

Tool/software:

Hi, I bought a IWR6843ISK, I was trying to program or understand the component, however I was not satisfied with the outcomes. I have a couple of questions, can anyone answer those to me and if possible send a personal text as well, so I can have a continuous conversation if needed. 

My Desired Output:  I wanted to detect how many people are there in a particular place, difference between a human and a pet, and how to understand the cloud points to extract couple more features. 

I am a beginner, and I needed some more help, which will be most appreciated. Along with my desired output, I have couple more question, which also to get answered. 

1. How to program the IWR6843ISK?

2. I only have IWR6843ISK, do I need any other components to do any more activities?

3. What is the programming language used for achieving the outputs we needed? 

4. How to set the height of the sensor, whenever the sensor is moved and placed in a different positions, and height? 

 

Honestly, I need help with a lot from the Scratch, and I feel like I am struck. Any help will be much appreciated. Thank you.

    Hi

    Sorry for the delayed response. You can use  IWR6843ISK to evaluate number of persons a room using 3D people tracking demo in radar toolbox. You can find the demo at the below location

    radar_toolbox_2_20_00_05\source\ti\examples\People_Tracking\3D_People_Tracking

    You can download the radar toolbox from the below location

    https://www.ti.com/tool/download/RADAR-TOOLBOX/2.20.00.05

    The location pointed above contains the pre build binary which needs to be flashed onto IWR6843ISK. 

    You can refer to the below video for flashing setup

    https://www.ti.com/video/6205855073001

    After flashing, and configuring the device in functional mode, you need to use the Industrial visualizer from below location to send configuration to the device and observe the outputs.

    You can find the industrial visualizer at the below location

    radar_toolbox_2_20_00_05\tools\visualizers\Applications_Visualizer\Industrial_Visualizer

    After you send the device as IWR6843 and demo as 3D People tracking demo in the visualizer, you need to send the below configuration

    radar_toolbox_2_20_00_05\source\ti\examples\People_Tracking\3D_People_Tracking\chirp_configs\ISK_6m_default.cfg

    Now, you can see the point cloud and the tracks appear for persons in the visualizer.

    However, you will not be able to distinguish between humans and pets with this application

    Hi Abhishek, 

    I hope you are doing good and in good health. I did all what you mentioned, and I can see the persons in the visualizers, however, I would like to make some more configurations as per my needs. I'll ask those question down which is bothering me, I would appreciate your help. 

    1. As you mentioned about the pre build binary, can I build my own binary as per my needs, if yes how can I do that, and what are all the customization we can do? 

    2. After flashing for my customized binary to the chip, how to make it stay there permanently, even if the chip is powered on or off, how can I make the make the binary stay there without flashing again and again when power is turned on and off. 

    3. When we are using the Visualizer we are using sending a cfg file, right? what are all the contents on it, what is the instructions we are sending to the visualizer? Also, how can I program it if I want to. 

    4. Also, is the binary we sending the main program on how the chip receives the data in the serial port or is it from the cfg file? 

    5. I tried opening the DSS and MSS file using the CCS, however it is giving me a error message of BIOS 6.73 is not installed, however, i tried installing and running it as an administrator on my desired location, even though it was not working. 

    6. Now we don't have an example program like 3D People Tracking Demo to differentiate between the pets and the humans, however will I be able to do that, will the chip allow us to do that, or are we only supposed to use the Demos in productions as well? But, if I can customize my chip on what I want that would be great, and if there is a way, I would appreciate if you help me teach me on how to get it. 

    Thank you for you help, I would appreciate if you help me figure out what I really want to do to achieve my goal. Thank you. Have a great day.

    Hi

    1. You need to import the projects into CCS and you can perform modifications and the resulting binary can be flashed on the device. If you need debug capability using JTAG, you will have to use IWR6843ISK with MMWAVEICBOOST board. You can find details about MMWAVEICBOOST at the following location

    https://www.ti.com/tool/MMWAVEICBOOST

    2.Once the binary is flashed, it is stored in the flash on the IWR6843ISK and every time you boot up, this binary stored will be loaded on to the device. So, same modified binary will be loaded on to the device after power up

    3.You can refer to the docs at the following link to understand each line in the cfg

    mmwave_sdk_03_06_02_00-LTS\docs\mmwave_sdk_user_guide.pdf

    radar_toolbox_2_20_00_05\source\ti\examples\People_Tracking\docs

    4.Please refer to radar_toolbox_2_20_00_05\docs\software_guides\Understanding_UART_Data_Output_Format.htm to understand UART data formats

    5.You will need to install the dependencies before extracting the project in CCS

    6.IWR6843 does not have software support to distinguish between humans and pets/non humans. IWRL6432 has support for classification which can be used to distinguish humans and non humans
