AWR1843: Time sync AWR1843 / DCA1000EVM raw data

Using the same HW trigger pulse you can trigger several devices at the same time.

Would this work for your use case?

thank you

Hey Cesar

Thanks for the response. The use case is measurement of waves from a vessel (ship). With the vessel moving we would like to correct the data with IMU's but those will need to be synced. 

I see now from a search on the forum there is a  Sync_in pin as a hardware trigger 

What would be a good reference on how to control that?

Hi Ryan,

The SYNC_IN pin can be used to provide a hardware trigger pulse to the AWR1843.

The only change is that in frame configuration of the AWR1843, you need to program it to expect a hardware trigger instead of software trigger by default.

If you are using the SDK and default OOB demo, this would be a parameter to the frameCfg command in the config file.

Best Regards,
