Some LCD modules come with control buttons mounted as part of the same assembly and setting the mode to "Read" allows the state of the buttons to be accessed, but we're not doing that in this project so we'll just hard-wire the R/W pin to ground to force it into Read mode That saves us one data line when connecting it to the ArduinoBy hard-wiring.

You can also create a file handle in managed code and pass it to an unmanaged API function. To illustrate this, we can modify the code that calls GetFileSize previously discussed. Instead of calling the unmanaged CreateFile function to get a handle to a file, we open the file in managed code and use the managed handle.

the R/W pin to ground on the module we're down to a total of 12 connections to the LCD module, 10 of which are using up the limited number of I/O lines available on the Arduino: eight data bits, Enable, RS, Ground, and 5V It s still a bit of a rat s nest, and uses up almost all of the limited number of I/O lines available on the Arduino The RS connection is the "Register Select" line, and it's used to switch between command and data modes in the LCD We can't tie it permanently HIGH or LOW like the Enable connection because the LCD drivers use it to initialize the module and then send data to it Luckily the HD44780 can also operate in 4-bit mode, a strange mode that's something like a cross between a parallel and a serial interface.

Figure 4-12. A list of filters with RSS links When you subscribe to a filter, your RSS reader will pick up changes to every case covered by the filter. The individual RSS items contain the basic information needed to identify the cases: Case number URL for further information Project Area Title Priority Assigned to Status Current estimate The RSS items include hyperlinks directly to the case and to the user to whom the case is assigned.

The revised C# code looks like this: // //open the file using managed code, then pass the //SafeFileHandle from the FileStream to the //unmanaged GetFileSize API // using(FileStream fileStream = new FileStream( "testfile.txt", FileMode.Open)) { Console.WriteLine("GetFileSize: {0}", GetFileSize(fileStream.SafeFileHandle, IntPtr.Zero)); } And the same code implemented in VB.NET looks like this: ' 'open the file using managed code, then pass the 'SafeFileHandle from the FileStream to the 'unmanaged GetFileSize API ' Using fileStream As FileStream _ = New FileStream("testfile.txt", FileMode.Open) Console.WriteLine("GetFileSize: {0}", _ GetFileSize( _ fileStream.SafeFileHandle, IntPtr.Zero)) fileStream.Close() End Using We open the file using a managed FileStream object and then use the SafeFileHandle property of the FileStream to obtain the SafeFileHandle. This safe handle is then passed to the unmanaged GetFileSize function. The unmanaged function sees only the actual handle. When the code is executed, we see the same results as the prior version: GetFileSize: 21
