Apart from the power supply pins, the SpeakJet has several other pins that need to be tied to either GND or VCC to force it to run in a mode that can be controlled externally by the Arduino Pin 11 is the active-low reset pin, so use a 10K resistor to pull it up to VCC to allow the SpeakJet to run Pin 12 is M1, the "Baud Configure" pin, which is also active-low We don't want the chip to enter automatic baud-rate configuration mode so use another 10K resistor to disable it by pulling it up to VCC as well Pin 13 is M0, the "Demo Mode" pin This one is active-high, so you can tie it straight to GND by putting a jumper wire on the underside of the board to connect pin 13 diagonally across to pin 5, the GND pin on the IC.

Most Win32 functions that use or return a string are available in ANSI or Unicode versions. This also applies to functions using a character rather than a full string. For each version, the root function name is the same, but each function name has a single character suffix that identifies the string or character type. A is appended for ANSI and W for wide (Unicode).

The only other SpeakJet pin that absolutely must be connected is pin 10, the RCX (serial input) pin That's the pin the Arduino will use to send data to the SpeakJet chip In this project we use a software serial communications library to connect the SpeakJet to one of the general-purpose digital I/O lines rather than tie up the hardware USART on digital pins 0/1, so use a short jumper lead and a 1K resistor to connect from Arduino digital pin 3 to SpeakJet pin 10 (see Figure 9-3)..

As an example, the Win32 API reference says that the GetComputerName function is available in ANSI and Unicode versions. This means two GetComputerName functions have actually been implemented: GetComputerNameA is the ANSI version and GetComputerNameW is the wide (Unicode) version. When calling this function from managed code, you need a way to determine the version that is executed. You control this with the CharSet field of the DllImport attribute. By simply changing the CharSet field, you can control which one of these functions is referenced. This behavior is based on hard-wired rules within PInvoke. The default if you do not specify this field is ANSI. Therefore, this C# declaration of GetComputerName will result in a call to GetComputerNameA, the ANSI version: [DllImport("kernel32.DLL")] public static extern bool GetComputerName( StringBuilder computerName, ref int size); We are passing a StringBuilder here rather than a System.String, since the function requires a preallocated buffer that it will fill with the computer name. The size argument is passed as a ref since it is updated with the number of bytes copied to the string buffer. We can execute the default version of this function using this C# code: StringBuilder buf = new StringBuilder(255); int size = buf.Capacity; GetComputerName(buf, ref size); Console.WriteLine("GetComputerNameDefault: {0}, {1}", buf.ToString(), size); The results on my machine look like this (obviously, your machine name should be different): GetComputerNameDefault: VIVALDI, 7 If we want to call the Unicode version of this function, all we have to do is declare it like this in C#: [DllImport("kernel32.DLL", CharSet=CharSet.Unicode)] public static extern bool GetComputerName( StringBuilder computerName, ref int size);
