impinj 编程接口

1、生成读写器：

ImpinjReader reader = new ImpinjReader);

以下说明reader是ImpinjReader的一个实例。

2、链接相关接口：

 reader.Connectip_str);        连接到指定的读写器上，ip_str：ip地址字符串；

 reader.Disconnect);    去连接；

3、启动和停止读写器

reader.Start);

reader.Stop);

4、配置相关接口

reader.QueryDefaultSettings);  获取读写器默认配置，返回Settings对象；

reader.ApplySettingssettings);  应用配置，settings是Settings对象；

5、事件回调函数：

5.1 tagReported相关属性

reader.TagsReported += OnTagsReported;       添加TagReported回调处理函数；

OnTagsReported格式如下：

OnTagsReportedImpinjReader sender, TagReport report)

6.settings配置属性

6.1 report相关的属性设置

settings.Report.IncludeAntennaPortNumber = true;
settings.Report.IncludeFastId = true;

6.2 filter相关属性配置

// Setup a tag filter.
// Only the tags that match this filter will respond.
// First, setup tag filter #1.
// We want to apply the filter to the EPC memory bank.
settings.Filters.TagFilter1.MemoryBank = MemoryBank.Epc;
// Start matching at the third word bit 32), since the
// first two words of the EPC memory bank are the
// CRC and control bits. BitPointers.Epc is a helper
// enumeration you can use, so you don’t have to remember this.
settings.Filters.TagFilter1.BitPointer = BitPointers.Epc;
// Only match tags with EPCs that start with “3008”
settings.Filters.TagFilter1.TagMask = “3008”;
// This filter is 16 bits long one word).
settings.Filters.TagFilter1.BitCount = 16;

// Next, setup tag filter #2
// This filter will apply to the User memory bank.
settings.Filters.TagFilter2.MemoryBank = MemoryBank.User;
// Start matching on the third bit bit pointer is zero-based)
settings.Filters.TagFilter2.BitPointer = 2;
// Only match tags that have the third bit of User memory set.
// Mask = 0x08 hex) = 1000 bin)
settings.Filters.TagFilter2.TagMask = “8”;
// Filter is 1 bit long
settings.Filters.TagFilter2.BitCount = 1;
// To test this filter, write 0x2000 to
// the first word of User memory.
// 0x2000 hex) = 0010000000000000 bin)

// Set the filter mode.
// Both filters must match.
settings.Filters.Mode = TagFilterMode.Filter1AndFilter2;

6.3 gpio相关属性配置

                // Start reading tags when GPI #1 goes high.
                settings.Gpis.GetGpi1).IsEnabled = true;
                settings.Gpis.GetGpi1).DebounceInMs = 50;
                settings.AutoStart.Mode = AutoStartMode.GpiTrigger;
                settings.AutoStart.GpiPortNumber = 1;
                settings.AutoStart.GpiLevel = true;

                // Stop reading tags when GPI #1 goes low.
                settings.AutoStop.Mode = AutoStopMode.GpiTrigger;
                settings.AutoStop.GpiPortNumber = 1;
                settings.AutoStop.GpiLevel = false;
