AWR1843: How to edit settings(Tx,Rx,Frequency etc)

Part Number: AWR1843
Other Parts Discussed in Thread: UNIFLASH

Hi, I want to program the AWR1843 to enable only one transmit antenna.
(I think that the SDK Demo file will enable all antennas.)

Which file should I edit to configure the device?
Which file should I edit and then convert to a bin file?
(I'm trying to flush with UniFlash.)

    Hi,

       I think you are trying to run the SDK demo using AWR1843 with one Tx alone, right? 

       Hope you are following the steps in C:\ti\mmwave_sdk_03_05_00_04\docs\mmwave_sdk_user_guide.pdf, section 3.3 for running the demos. In there, while you send one of the cfg files (present in: C:\ti\mmwave_sdk_03_05_00_04\packages\ti\demo\xwr18xx\mmw\profiles) or you can use the GUI in browser based visualizer to set the number of Tx antennas. Ideally you would not need to rebuild the bin file again for changing parameters sent via cfg file. 

       Let me know if you have any questions.

    Thanks and Regards,

    Akshay

    Hello and thank you for answering the question.

    There are roughly two types of millimeter-wave radar setting methods.

    ・ If you want to enable only the transmitting antenna Tx1 by the former method,
    C: \ ti \ mmwave_sdk_03_05_00_04 \ packages \ ti \ demo \ xwr18xx \ mmw \ profiles, profile_3d.cfg, line 39, channelCfg should be arranged as follows.

    channelCfg 15 1 0

    Also, the reply said'send one of the cfg files', how do you send this?
    Is there any manual etc.?

    -In the latter method, it is said that mmWaveDemoVisualizer is used for transmission, but here, after entering a command to enable only one transmission antenna, turn off the power of the millimeter wave radar.

    After that, if you turn on the power again, is it okay to assume that only one transmitting antenna is enabled?

    that's all

    Hi,

        Request to please have the user manual found in path: C:\ti\mmwave_sdk_03_05_00_04\docs\mmwave_sdk_user_guide.pdf handy with you for following the steps I am listing here to be done:

    1. To run the demo, please follow the steps in section 3.3 of the user-guide starting from the beginning to get the entire demo up and running on the device.
    2. Yes the cfg files you have identified are the right ones. You will have to use load file from pc tab to send the config file in the corresponding step to load the cfg file via pc.
    3. Regarding the arguments of cfg file, I would request you to please look through section 3.4 of the user guide which mentions what are the parameters for each for the configuration.
    4. As you have pointed out,   channelCfg 15 1 0 enables only one Rx as per the table given in section 3.4 of the user-guide. To enable a single Tx alone as you had wanted, I would request you to check the chirpCfg (in same table of section 3.4 of user-guide) which contains the mask for Tx enabling/disabling (means you will have to remove two chirpCfg commands from the cfg file you have chosen as each chirpCfg enables chirp transmission through single Tx).

         If you follow the instructions (as in section 3.3) as shown in user-guide you will be able to get demo up and running as per the configuration you had wanted.

         Let me know if you have any questions.

    Thanks and Regards,

    Akshay.
