AWR6843: Controlling the MMWave interface from MSS and DSS

Lee Lemay

Part Number: AWR6843

Hello experts,

I'm interested in running some of the mmwave commands from the MSS and some from the DSS.
I have configured the domains to be DPM_Domain_DISTRIBUTED.

The DPC is running on the DSS.

MSS:
MMWave_open
MMWave_config

DSS:
MMWave_start

The plan is to pass the MMWave_Handle from the MSS to the DSS as an argument in DPM_ioctl, then access it in the DSS to start the sensor.
Is this possible?

Thank you for your guidance.

Hi,

Are you working off of a particular example project? If so, could you reference it here? It would also be good to have an understanding of the HW and SW versions you are using.

Thanks,

Clinton

Hi Clinton,

We've pretty heavily modified the base example project we started from, and we're no longer certain which one it was.
Is it necessary to configure the executionMode of the MMWave to MMWave_ExecutionMode_COOPERATIVE for this to work?
If so, can you recommend an example project that does this that we can work from?

If there are any other basic configuration options that we should set to enable this, we're all ears.

Thank you for your help.

It looks like the high_accuracy_68xx_dss and high_accuracy_68xx_mss demo projects should serve as a good guide.
I'll let you know how it goes. Thank you for your help.
