AWR1642: DCA1000EVM, Trigger frame, Visual Studio 2015, Windows

Part Number: AWR1642
Other Parts Discussed in Thread: DCA1000EVM

Hi All:

I have tried using mm_wave_studio to run lua scripts, everything is ok.But when I tried to collect data using "DCA1000EVM_CLI_CONTROL",I had received a "NO LVDS DATA" prompt.

We want to control the equipment in our software,the platform is windows,the development tool is Visual Studio 2015, i have tried to install other versions of studio or SDK, but that is useless.

I think it may be due to not send a trigger frame, or other problems, by reference guide.

This problem has troubled me for a long time, I hope you can help me, thank you very much.

    Hello Wang,

    Please be noted that there are two exe for DCA1000 - 'DCA1000EVM_CLI_Control.exe' and 'DCA1000EVM_CLI_Record.exe'

    First is to configure and control DCA1000EVM and second is to record the LVDS data.

    Refer TI_DCA1000EVM_CLI_Software_UserGuide.pdf at 'mmWaveStudio\ReferenceCode\DCA1000\Docs' directory.

     

    Regards,

    Hello Jitendra,

    I am sure that my first step is to configure the FPGA(DCA1000EVM_CLI_Control.exe fpga cf.json), then configure the record(DCA1000EVM_CLI_Control.exe record cf.json), finally send the start command(DCA1000EVM_CLI_Control.exe start_record cf.json).

    I have checked the DCA1000 source code. When I send the start command, the "DCA1000EVM_CLI_Control.exe" will start the "DCA1000EVM_CLI_Record.exe" process. Should I send other commands or run other tools?

    I am sure that the js file used by the studio and the CLI tool is the same file.And the data is being sent in real time on the "auxiliary data port",so, I am not sure where the problem is.

    Hello,

    When you trigger the capture using exe, do you see DATA_TRAN_PRG LED on DCA1000EVM blinking?? 

    And optionally use *record.exe to trigger the capture after it is configured by *control.exe

    And make sure that you have connected only one network connection (not ethernet and wi-fi together).
