IWR1443: Continuous Streaming Mode

Part Number: IWR1443
Other Parts Discussed in Thread: AWR1243

Hello,

I would like to operate our IWR1443 device in CW mode for some testing and measurements. We are using a semi-custom MSS to operate our radar. I have two questions about this mode:

1. What is the difference between API functions rlEnableContMode and rlSetContModeConfig?

2. What is the format of the LVDS/CSI output data?

Thanks for your help,

Antonio

    Hi Antonio,

     rlEnableContMode, as suggested by the name, enables/disables FMCW radar continuous mode

    rlSetContModeConfig sets the FMCW radar continous mode properties like Start Freq, TX power etc. In continuous mode, the signal is not frequency modulated but has the same frequency over time.

    LVDS/CSI2 is covered in chappter 13 of TRM (technical reference manual) 

    There's also a document describing how to interpret the ADC output data (LVDS) using capture demo of mmwave SDK.

    This may also help.

    Let me know if you have any further questions.

    Thanks and Regards,

    Michelle

    Hi Michelle,

    I'm sorry for my mistake, I meant to ask what is the difference between rlEnableContMode and rlDeviceSetContStreamingModeConfig. 

    Thanks,

    Antonio

    Antonio,

    rlDeviceSetContStreamingModeConfig configures the transfer of captured ADC samples continuously without missing any sample to an external host. This API is valid only for AWR1243 mmWave device when mmWaveLink instance is running on External Host Processor.
    According to this description, you do not need to run this API on IWR1443 device.
