Overview

Developing an RFID application in C# VS 2005Basic functions and event handlersFocus on IF61 reader

Slide 3 Developer Conference 2007

Create Basic Project in C#

Select Windows Application

Slide 4 Developer Conference 2007

RFID References

Add RFID class references to your project

Slide 5 Developer Conference 2007

RFID References

using Intermec.DataCollection.RFID;

Slide 6 Developer Conference 2007

Now lets add the basic features to your app

Create reader objectAdd Event HandlersAdd Tag Handlers

Slide 7 Developer Conference 2007

Create RFID Object

LocalHoststring tConnection = "TCP://" + "127.0.0.1" + ":2189";

Defaultsbrdr = new BRIReader(null, tConnection);

With OptionsRead buffer sizeEvent buffer size

BRIReader.LoggerOptionsAdv LogOp = new BRIReader.LoggerOptionsAdv();LogOp.LogFilePath = ".\\IDLClassDebugLog.txt";LogOp.ShowNonPrintableChars = true;brdr = new BRIReader(this, tConnection, 22000, 2000,LogOp);

Slide 8 Developer Conference 2007

Create Event Handlersprivate int AddEventHandlers() { //********************************************************************* // Add the event handler to handle the tag events and trigger pulls. // Not all of these are used but added as samples of what are available. //*********************************************************************

try {

this.brdr.EventHandlerRadio += new Radio_EventHandlerAdv(brdr_EventHandlerRadio); this.brdr.EventHandlerTag += new Tag_EventHandlerAdv(brdr_EventHandlerTag);

this.brdr.EventHandlerGPIO += new GPIO_EventHandlerAdv(Form1_EventHandlerGPIO); } catch { return -1; } return 0; }

Slide 9 Developer Conference 2007

Tag Event Handler

this.brdr.StartReadingTags(null, "COUNT ANT", BRIReader.TagReportOptions.EVENT);

void brdr_EventHandlerTag(object sender, EVTADV_Tag_EventArgs EvtArgs){ //********************************************************************* // This function process any tag that is returned as an event. // This function is in use when you send a READ with REPORT=EVENT //********************************************************************* bool bStatus = false;

RspCount = 1; RspMsgList[1] = EvtArgs.DataString.ToString();

bStatus = CheckIfTagIDIsInDBase(RspMsgList[1]);}

Slide 10 Developer Conference 2007

Polling For Tags (Report=No)

this.brdr.StartReadingTags(null, "COUNT ANT", BRIReader.TagReportOptions.POLL);

bStatus = brdr.PollTags();

foreach (Tag tt in brdr.Tags){ RspCount++; RspMsgList[RspCount] = tt.ToString(); if (tt.TagFields.ItemCount > 0) { foreach (TagField tf in tt.TagFields.FieldArray) { RspMsgList[RspCount] += " "; RspMsgList[RspCount] += tf.ToString(); } } }

Slide 11 Developer Conference 2007

Add GPIO Event Handler

void Form1_EventHandlerGPIO(object sender, EVTADV_GPIO_EventArgs EvtArgs)

{ //process gpio trigger events if (EvtArgs.TriggerNameString.Equals("ENTER_ON")) { //your code here } else if (EvtArgs.TriggerNameString.Equals("EXIT_ON")) { //your code here }}
