AWR1642: numADCSamples & trigger possibility on subframe

Part Number: AWR1642
Other Parts Discussed in Thread: AWR1243

Dear Experts,

could You please help with the following requests:

1) The parameter "numADCSamples" is available in both frame configuration and profile configuration.

- do they have a different purpose or function?

- is the one from the frame config overwritten by the profile config?

2) Is there a way to have a trigger on a sub-frame? Or is this only possible with actual frames?


Many thanks and best regards,

Gregor

    Hi Gregor,

    numADCSamples is relevant only in AWR1243 and it configures how many samples per chirp need to be sent on LVDS/CSI2. This needs to be documented correctly in API document  and will correct this in next release.

    I didn't fully understand the 2nd question. I assume, you are referring to HW_TRIGGER (SYNC_IN pulse).

    You configure the trigger select for a frame or advance frame. In case of legacy frame, SYNC_IN needs to be triggered for every frame. For Advance frame, SYNC_IN pulse needs to be generated for every burst in the sub-frame.
