The External Adapter
Print QR Code 2d Barcode In C#.NET
Using Barcode generation for .NET framework Control to generate, create Quick Response Code image in VS .NET applications.
The external adapter uses a serial to 1-Wire converter7 that is attached to the auxiliary serial port (serial1) of TINI s microcontroller All TINI hardware designs (including the TBM390) from Dallas Semiconductor include the external adapter chip The external adapter is a full-featured port adapter capable of controlling 1Wire networks that cover a large area and potentially have many attached devices It is also capable of the power delivery required by many 1-Wire chips to perform special functions such as measuring temperatures and converting analog voltages and currents to digital outputs Since the external adapter is far more capable, it is the one used for almost all TINI 1-Wire applications Most of the examples in this chapter will use the external adapter

Determining an Adapter s Capabilities
Creating QR Code In VS .NET
Using Barcode creator for .NET Control to generate, create QR Code image in VS .NET applications.
The previous section provided a description of the two 1-Wire adapters supported by TINI This same information is encapsulated in an adapter instance and can therefore be determined programmatically The methods can* (canOverdrive, canDeliverPower, and so on) de ned in DSPortAdapter return the boolean result true if the underlying adapter has that particular ability Listing 43 AdapterFeatures

Generating Code 39 Extended In Java
Using Barcode printer for Java Control to generate, create ANSI/AIM Code 39 image in Java applications.
The AdapterFeatures program, shown above in Listing 43, creates instances of TINIInternalAdapter and TINIExternalAdapter and queries both for their capabilities Running AdapterFeatures produces the following output

Code 128 Code Set A Encoder In .NET
Using Barcode printer for .NET Control to generate, create Code 128C image in .NET framework applications.
We see here that both adapters are capable of communications at overdrive speeds, but only the external adapter is able to support the exible timing mode used to communicate with 1-Wire chips over long line lengths

Searching for 1-Wire Devices
Encoding Bar Code In .NET
Using Barcode printer for .NET Control to generate, create barcode image in .NET framework applications.
One of the major roles served by an adapter is managing the address discovery (or search) process by which the address of every device attached to the network is discovered The super class of all adapters, DSPortAdapter, contains several methods used to con gure and execute the discovery process The method getAllOneWireDevices returns an Enumeration of OneWireContainer objects (containers are described in Section 44) Listing 44 uses the getAllOneWireDevices method to obtain a census of all chips on the 1-Wire network controlled by TINI s default (external) adapter Listing 44

When executed, Census displays a string representation of every 1-Wire address attached to the network by invoking the getAddressAsString method on each OneWireContainer object

There are a total of ve 1-Wire devices in this example con guration 8 Four of them have the family id of 0x12 These devices are all DS2406-addressable switches The device with family id 0x21 is DS1921 Thermocron iButton 9 Thermocrons log temperature over time for the purposes of generating time versus temperature histograms We ll be using this same network con guration for the next few examples The important property of this con guration is that we have devices from different 1-Wire families on the same network Since our simple network consists of only ve chips, it doesn t take long to search the entire network So, for example, if we re interested only in Thermocrons, it wouldn t be unthinkable to just get an Enumeration of all available devices and slug through the Enumeration looking for Thermocrons However, if the network contained tens or even hundreds of devices, this approach would be far too cumbersome For this reason, DSPortAdapter de nes several methods that allow the targeting or exclusion of certain families These methods greatly improve the ef ciency with which an application can identify devices of interest
8 The speci c test con guration used here is the Systronix 8x1-Wire Digital I/O board with the Thermocron inserted into the iButton clip See http://wwwsystronixcom/ expansion/8x1wire/81whtm for details on the 8x1-Wire Digital I/O board 9 More detailed information on the Thermocron iButton can be found at http:// wwwdalsemicom/datasheets/pdfs/1921pdf
