IWR6843: Is hardware trigger supported?

Dennis Olsson

Part Number: IWR6843

According to the user guide in the SDK (at least 03_02_00_04 and 03_03_00_03) the hardware trigger is not supported.

From page 22 (SDK 03_03_00_03):

I have confirmed that it works, I get frames when I put the pin high and none when low, but there is no sense in relying on it if it is not supported (and risk being removed or can cause problems).

Hi Dennis,

The Sync-IN trigger is a device feature which is tested at device and mmWaveLink (DFP) level. The documentation in SDK user guide just means that it is not tested and hence supported at an SDK/OOB demo level, however it should not be interpreted to mean that the feature will be removed from the device.

Is it possible for you to provide some use-case information about how you plan to use the feature?

Thanks

We are using multiple sensors of different types (and multiple radars) and want to

synchronize the data to a known world-time for logging, and
be able to adjust frame start on the fly from other software/hardware to handle different types of interference

Then I interpret your answer as we can use the feature and just do software modifications to adopt to changes if the behavior is altered.

Hi Dennis,

That is correct. Essentially, the feature will always be available in the device.
