AWR1843AOP: Assistance Needed with AWR1843AOP Configuration for AreaScanner LAB

Part Number: AWR1843AOP
Other Parts Discussed in Thread: AWR6843AOP

Hello,

I would like to use the areascanner lab with the AWR1843AOP. I have adapted the project to the processor accordingly. However, I have encountered some undefined aspects as indicated below:

STATICDET_MAX_NUM_ANT_FOR_HEATMAP STATICDET_HEATMAPGEN_NOTCH_ENABLE

I am in need of your assistance regarding how to populate these undefined details.

I have found where this information is located - specifically in the staticdetprocdsp.c and staticdetprocdsp.h files within the mmwave_industrial_toolbox_4_12_1\labs\common\src\dpu\staticdetproc folder.

The values defined for AWR6843AOP are present in these files, but they have not been defined for AWR1843AOP.

For example, in the staticdetprocdsp.h file, the defined values for AWR6843AOP are as follows:

#ifdef XWR68XX_AOP_ANTENNA_PATTERN

#define STATICDET_NUM_ADOA_ANT 4 // has to be 4 or 8

#define STATICDET_NUM_EDOA_ANT 4 // has to be 4 or 8

#define STATICDET_NUM_ADOA_SET 1

#define STATICDET_NUM_EDOA_SET 2

#define STATICDET_HEATMAPGEN_NOTCH_ENABLE 1

#define STATICDET_NUM_EDOA_ANT_TOT STATICDET_NUM_EDOA_ANT * (STATICDET_NUM_EDOA_SET << STATICDET_HEATMAPGEN_NOTCH_ENABLE)

#define STATICDET_NUM_ADOA_ANT_TOT STATICDET_NUM_ADOA_ANT * (STATICDET_NUM_ADOA_SET << STATICDET_HEATMAPGEN_NOTCH_ENABLE)

#define STATICDET_MAX_NUM_ANT_FOR_HEATMAP 4

#endif

I am unsure about how to generate these values for AWR1843AOP.

Additionally, I have noticed that the functions within staticdetprocdsp.c utilize the information we create. Are these functions specifically written for AWR6843AOP, or will they work within AWR1843AOP once we populate all the necessary #define values?

Thank you for your assistance.

Best regards,

EMRE

  • Hey Emre,

    Thank you for contacting us regarding your question. I'm still looking into your issue, so I apologize for the delay, but I will try to have a concrete answer within the next 24 hours.

  • Hey Emre,

    I apologize for the delay, but there a few bits of information to share. First, you should be able to reuse the AWR6843AOP macro definitions for the AWR1843AOP as the antenna configuration is the same between devices. In other words, you can build the source code using the "aop" configuration as described in the user guide for the area scanner demo - linked below - and should be able to flash the binary onto the AWR1843AOP. Note: adding another build configuration for the AWR1843AOP EVM is possible but is more complicated than the previously mentioned solution. We may be able to further discuss how you can do so, but I would highly recommend modifying the existing AWR6843AOP files as long as there are no issues.

    Additionally, if you haven't already done so, the area scanner chirp configs should be modified to be compatible with the AWR1843AOP as its frequency range is different from the AWR6843AOP. It will need to be changed from a starting frequency of 60.5 GHz to at least 76 GHz and no more than 77.55 GHz based on the ramp end time and frequency slope for the chirp configuration. This can be done by copying the area_scanner_68xx_AOP.cfg and changing the following line:

    profileCfg 0 60.5 100 25 69 0 0 50 1 256 6000 0 0 30 -> profileCfg 0 77 100 25 69 0 0 50 1 256 6000 0 0 30 

    For more details on the CLI commands used in .cfg files, see Section 4.6 of the area scanner demo which includes links to the standard SDK 3 CLI commands, tracking commands, and detection commands. I would also recommend taking a look at that section if you would like to further tune the performance of the device.

    Finally, we recommend switching over to the newest radar toolbox found at the link below. This will contain the newest area scanner source code and documentation and will allow us to better support you if you need further help.
