EVAL-ADIS2 board external sync

Hi Greg,

Thank you for your post!  What does it have to be in Burst Mode, if you are using the evaluation tools?  As long as the data is collected, for each frame, does it matter if the evaluation software uses the Burst or individual register reads (standard for eval software)?  With respect to the External Sync, let me review the ADIS16IMU4/PCBZ Wiki Guide and see if that has enough information to figure out the correct pin (on J1), to drive the external sync.

Hi Mark,

Eventually I need to develop an FPGA to talk to a collection of sensors, one of which is the ADIS16465. I was hoping to use the evaluation board to confirm waveforms in burst mode but if that is not possible that is ok. More importantly I want to get external sync working on the evaluation board to prove out my design.

Here are the pin assignments, for the ADIS16IMU4/PCBZ's connector: Here is the direct reference:

Is there a way to access pin 14 on J1 while it is connected to the EVAL-ADIS2 board? I'd like to drive it with some stand alone circuitry while at the same time use the evaluation software to read registers. Also, is DIO2 (J1.14) an input by default?

That is a great point! Sorry I didn't start with that perspective in mind.  The DIO1, DIO2, DIO3 and DIO4 distinctions come from the ADIS16375, ADIS1648x and ADIS1649x products.  Their input/output definition actually happens in the IMU products, not on the EVAL-ADIS2 board.  In your case, the only thing that matters is making sure that the DIO2 pin connects to J1, pin 14.  if so, then than e-hole provides you with a point of contact for your external clock, on the ADIS16465.  Hope that helps! 

Perfect, that makes it very easy to set up an external sync.

Thanks for the help

You bet! Good luck with this! 

While I have not been able to validate this myself, the software developer has tested the Burst Read function, which is available through a check box, in the Data Capture menu.  He confirms that it works correctly and should meet the needs that you are describing. If you need any help with this, can you post a new discussion, which focuses on the implementing the Burst, using the IMU Evaluation Software? Thank you!
