示例1: Main
public static void Main()
{
Debug.Print("BLE Shield");
var port = SerialPorts.COM1; // using D0 & D1
//var port = SerialPorts.COM2; // using D2 & D3
var bleShield = new SerialPort(port, 19200, Parity.None, 8, StopBits.None);
bleShield.DataReceived += (sender, args) =>
{
var receiveBuffer = new byte[16];
int bytesReceived = bleShield.Read(receiveBuffer, 0, receiveBuffer.Length);
if (bytesReceived > 0)
{
Debug.Print("Bytes received: " + bytesReceived);
Debug.Print(new String(Encoding.UTF8.GetChars(receiveBuffer)));
}
};
bleShield.Open();
while (true)
{
var random = new Random();
var sendBuffer = new byte[4];
random.NextBytes(sendBuffer);
bleShield.Write(sendBuffer, 0, sendBuffer.Length);
Thread.Sleep(1000);
}
}示例2: ExampleThreadFunction
public static void ExampleThreadFunction()
{
// bit rate change acording your GPS
SerialPort serialPort = new SerialPort("COM3", 4800);
serialPort.Open();
//here we create file in SD card main folder
string rootDirectory = VolumeInfo.GetVolumes()[0].RootDirectory;
FileStream FileHandle = new FileStream(rootDirectory + @"\gps.txt", FileMode.Create);
while (true)
{
int bytesToRead = serialPort.BytesToRead;
if (bytesToRead > 0)
{
// all struff from GPS streams in to file
byte[] buffer = new byte[bytesToRead];
serialPort.Read(buffer, 0, buffer.Length);
Debug.Print(new String(System.Text.Encoding.UTF8.GetChars(buffer)) + "\n");
FileHandle.Write(buffer, 0, buffer.Length);
Thread.Sleep(500);
}
// Cleaning
Debug.GC(true);
Debug.EnableGCMessages(false);
}
