PGA460-Q1: Set up procedures of 2 PGA460 models for triangulation measure

Part Number: PGA460-Q1
Other Parts Discussed in Thread: PGA460, ENERGIA

Hi, TI team,

I'm trying to use 2 PGA460-Q1 models for triangulation measure (one for transceiver and another one for receiver), and I can't exactly understand step by step set up procedure even after reading the section 3.1 from "PGA460 Array of Ultrasonic Transducers for Triangulation and Tracking".

Could you please guide me or if there is any tutorial document which describe more clearer.

Many thanks.

Shihyu.

  • Hi Shihyu,

    Thank you for your question.

    The Application report you are referencing (SLAA783) is certainly an interesting use case for ultrasonic sensors. Triangulation with ultrasonic can be challenging to realize success with, therefore, we do not have much additional content on the topic. The Energia code example included here: Code Example has a useful software example for the process of using multiple PGA460 devices for triangulation.

     

    For clarity on section 3.1, the PGA460 datasheet contains more information on the process for generating and receiving ultrasonic signals.  

    Finally, this application report includes information on developing software for the PGA460: PGA460 Software Development Guide

     

    Please let me know if you have any further questions,

    Thank you,

    Jacob
