Original question:

AWR1843BOOST: UART Communication with Python

AWR1843BOOST: UART Package

Part Number: AWR1843BOOST

Hello,

I'm sorry for the late reply. I worked on your message which is your return for my question. https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1073433/awr1843boost-uart-communication-with-python

I looked all answers in links you sent. I prepared a word documentation that is included code parts about you told in this link. https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/970380/ccs-awr1843boost-where-can-i-find-the-detailed-description-of-output-data-format-for-lab00007-medium-range-radar   You can see the document in attachment.

I also examined mrr_parsed.txt documentation you sent to Lei. I also added this document as attachment.

I tried to understand datas which sends from AWR1843BOOST. I watched the UART line with Dochlight Scripting program and I got some ununderstandable datas like this.

Then I set it as Getting Started Guide and watched on GUI.

I tried to watch on both GUI and  Dochlight Scripting at the same time but of course UART line doesnt allow it. Then I closed the GUI screen and watch on  Dochlight Scripting again. I saw that the data again.

As far as I understand from your posts, it must first be sending the data "0x0102, 0x0304,0x0506,0x0708" called magic_word. Then, data such as version, totalPacketLen, platform should be reached. However, I have never come across magic_word in the UART line that I examined. I want to make sense of this data before reading it with python. I'm new to coding, so I want to first see and understand the data packets sent with the Dochlight Scripting application.

I tried to explain things that I did not understand, I hope I was able to explain. I would really appreciate if you can help.

    Hi,

    If I understand correctly you are trying to understand the UART data sent by the MRR demo.

    One way to understand it is to see the matlab gui parsing code

    labs\lab0007_medium_range_radar\gui\MRRvisualization\read_serial_port_and_plot_object_location.m

    See barker_code detection - lines 151.

    Thank you

    Cesar

    Hello,

    What I want to ask is this. I'm going to use the AWR1843BOOST development kit and load and run the medium range radar code without making any changes to the software. I will process the distance and speed data by fixing it on a walking robot, communicating with a system with python software and making sense of the UART data it sends.

    Therefore, I need to understand the data that the card sends from the uart line. When I watch the UART line, I cannot understand the incoming data.

    Yes, this data is read by the GUI in

    labs\lab0007_medium_range_radar\gui\MRRvisualization\read_serial_port_and_plot_object_location.m

    Thank you
