Linux/PGA460-Q1: PGA460-Q1

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

Tool/software: Linux

Dear All,

i will be highly for your help.

Please, advice the configuration parameters (EEPROM, Thresholds) for the PGA460-Q1 controller. It is necessary for the operation with a 40kHz sensor (automotive parking ultrasonic sensor such as for JSN-SR04T) and the possibility of obtaining distances from 20cm to 4m.

Thank you in advance!

Best regards,

Taras

    Hi Taras,

    PGA460 configuration parameters are tailored based on sensor and application. It is not possible to give configuration parameters here for you. However we a lot of application notes and training material on how to get started with PGA460 for measuring objects in air. You can start with default configuration of the EVM with your transducer and transformer pair and start tweaking parameters based on your need.

    Please see this page: e2e.ti.com/.../770492.

    After reading the data sheet and EVM user guide I would recommend:

    1. PGA460 Ultrasonic Module Hardware and Software Optimization
    2. PGA460 Frequently Asked Questions (FAQ) and EVM Troubleshooting Guide

    There are also good training videos to watch
