GPI Debounce Tutorial

Overview

This Tutorial provides a walk-through of the steps to perform get and set debounce time operations using RFID3 API

Create The Project

• Start by creating a new project in Android Studio. For help, see the Android Studio tutorial.
• Refer Hello RFID to prepare basic setup to work with RFID Reader and then follow this guide

Details

This tutorial will describe the apis for setting and getting the debounce time.

Setting it up

The following are the steps to get and set debounce time to the reader

• Create Reader Management Object
• Create a LoginInfo object and Login to the Reader.
• Perform get and set debounce time operations.

Creating a ReaderManagement object.

// create and initialize the Reader Management object.
    ReaderManagement readerManagement = new ReaderManagement(); 
                                                                                                      
                                                

Creating a LoginInfo object and perform login operation.

//Creating a LoginInfo object and perform login operation.
    LoginInfo loginInfo = new LoginInfo("hostName", "userName", "password", SECURE_MODE.HTTP, false);
    try {
            readerManagement.login(loginInfo,READER_TYPE.FX);
        } catch (InvalidUsageException e) {
            e.printStackTrace();
        } catch (OperationFailureException e) {
           e.printStackTrace();
        }

Performing operation

Get Debounce Time.

// Get GPI Debounce Time.
    try {
        int gpiTime = readerManagement.getGPIDebounceTimeMilliseconds();
    } catch (InvalidUsageException e) {
        e.printStackTrace();
    } catch (OperationFailureException e) {
        e.printStackTrace();
    }

Set Debounce Time.

// Set Gpi Debounce Time.
    try {
        readerManagement.setGPIDebounceTimeMilliseconds(15);
    } catch (InvalidUsageException e) {
        e.printStackTrace();
    } catch (OperationFailureException e) {
        e.printStackTrace();
    }
