Q:
Will the EVAL-ADIS and IMU Evaluation Software enable capture of the first data sample that the ADIS16485 produces after it powers on?
---------------------------------------------------------------------------------------------------------------------------------------
A:
Yes, with the use of an external supply and some quick button pushes, these evaluation tools will support this. Here are the steps, with supporting pictures:
- Get the IMU Evaluation software running and verify that the ADIS16485 is working with the USB-based, +3.3V supply.
- Go into the Data Capture Menu
- In the Data Capture window, select the registers for data acquisition, the total number of samples to collect in the record and the file name/path, but DO NOT click on Start yet.
- Change the JP1 jumper setting on the EVAL-ADIS to "Ext," as shown in the following picture:
- Connect an external supply to J3, as shown in the following picture. NOTE: These power inputs have no transient or reverse-polarity protection. The ADIS1648x products place transient current demands on VDD during start-up. Reference product datasheet for more details on the transient demands. Make sure that the supply, at J3, does not experience excessive overshoot (VDD < 3.6V peak) and is correctly oriented.
- In the Data Capture window, click on Start, then turn the +3.3V supply on. Between the time that you click on Start and the first data sample must be less than 5 seconds.
I hope that this helps and look forward to your comments!
