AWR1843: Data Configuration from DCA1000EVM

Part Number: AWR1843
Other Parts Discussed in Thread: DCA1000EVM, AWR2944, AWR2243, AWR1642

Tool/software:

Hi Experts,

Asking your guidance on this query from cx:

I am working on getting AWR1843 data using DCA1000 EVM.

I got the data, but I am unable to understand the config used for getting this data.

I have doubts regarding understanding the config data uploaded while getting data from DCA1000EVM and AWR1843

1) How to select two azimuth antennas? Which of Tx0,Tx1,Tx2 are azimuth antennas for AWR1843
2) Should the 'Format' in ADC config be 'complex2x' or 'complex1x' for 2 bytes for real and 2 bytes for imaginary representation
3) the downloaded config file is in .xml format. I am unable to understand it. How to download the config file .cfg format like ike as given in 'profile_2d.cfg' in folder "C:\ti\mmwave_sdk_03_06_00_00-LTS\packages\ti\demo\xwr18xx\mmw\profiles"
4) The saved manage chirp sscreenshot only Tx1 enable, with chirp start index,chirp end index =0, what about other transmitter which was enabled?

So finally, these are the screenshots and the questions I need resolving:

Thank you for your assistance.

    Here, if you try to save the configuration from studio then it will be saved in an xml file only. The user cannot generate the cfg file from here. If you want to get the cfg file then you can refer to section 3.6 in mmwave_mcuplus_sdk_user_guide.pdf there in the table the format is well mentioned. You can take any of he .cfg file for reference from mmwave_mcuplus_sdk_04_05_00_01\ti\demo\awr294x\mmw\profiles\ddm_awr2944.

    You can enable the transmitters from studio Gui based on your application. Please go through the mmwave studio user guide for better understanding about the same.

    Hi Shruti,

    Can you help this follow up query from a user?

    1) I know the layout of AWR1843. On layout Tx1, Tx3 are azimuth and Tx2 is elevation antennas. But in mmWave studio the options are Tx0, Tx1, Tx2. That's why I am asking which of the two of Tx0, Tx1, Tx2 are azimuth antennas?

    2)So if I select complex1x gives it gives real data only and complex2x gives complex data. Right?

    3) You have given wrong pdf. mmwave_mcuplus_sdk_user_guide.pdf is for AM273X, AWR2243, AWR294X. The same info for AWR1843 is available in mmwave_studio_user_guide.pdf. All the info to understand the downloaded .xml config file is not given in this document. That document only explains the .cfg config file. For example, I used two chirpCfg for two Tx I used with TDM-MIMO format. The .xml file has only chirpCfg command.

    Here are an extra doubt I have
    4) What is the maximum number of frames I can get using DCA1000 EVM. Is there a provision for getting continuous data, for example, mmwave_studio_user_guide.pdf tells that mentioning numFrames = 0 in the frameCfg command means infinite number of frames.

    5)How to set the two Tx in TDM-MIMO like as shown in as shown in Fig. 8 (section 4.1) of MIMORadar.pdf (SWRA554A.pdf). see below fig.
    Here is how I set it:
    "in the chirp section of sensorConfig tab of mmWaveStudio:"
    enable Tx0 only and put Start Chirp for Cfg = 0 and End Chirp for Cfg = 0 values, Profile id = 0 then click “set”.
    enable Tx1 only and put Start Chirp for Cfg = 1 and End Chirp for Cfg = 1 values, Profile id = 0 then click “set”
    "in the frame sectionof sensorConfig tab of mmWaveStudio:"
    put Start Chirp Tx = 0, End Chirp Tx = 1
    Is the above procedure correct for TDM-MIMO like as shown in as shown in Fig. 8 (section 4.1) of MIMORadar.pdf?

    6)I got this error while using mmWave studio. Could you tell what does it mean and how to resolve it.

    ****

    Thank you.

    Hi Artzy,

    In the attachment that you shared; I could not see the Frame Ended log, are you doing the post processing before the frame stop?

    Can you first try with the configuration given in the user guide and see if you are getting the same error there as well.

    Please follow the sequence (numbers are indicated) given in the above image.

    for this, you can consider the TX1,TX2,TX3(in the layout) as TX0,TX1,TX2(in the studio).

    Hi Artzy,

    You can refer to page number 29 (section 9.3) in the studio user guide. The user guide has snapshots with sequence mentioned, you can follow the same.

    Hello Shruti,

    Thank you very much for your usual and valuable support.

    We got the solutions for everything except these 2:

    1) So you are saying if I select Tx0, Tx1, then I am selecting one azimuth, one elevation antenna? I don't think it's the configuration used. Why does in the demo video www.ti.com/.../5827389052001 they take one azimuth, 1 elevation antennas.

    2) How can I get continuous data in DCA1000 EVM? The mmWave studio user guide also says that I can use the "stop frame" button to stop receiving the data (required only in the case of infinite frames), but I don't know how to configure it for getting infinite data.

    The Antenna design of AWR1642 is different from AWR1843. In the video, the parameters have been configured for AWR1642, in that device, we have 2 azimuth Tx only, there's no elevation antenna.

    In AWR1843, TX0,TX2 are the azimuth and TX1 is the elevation antenna. You can use the same.

    Hi Shruti,

    Thank you.

    But setting the number of frames to zero is not giving any data. I tried it.

    Hi Artzy,

    Can you check with a different board if possible?
