GPS接收机(五)基于C#的GPS软件上位机

前面已经搭建了一个可以接受GPS数据的简易接收机，接下来将要编写一个上位机处理接收到的数据，并进行处理显示。

效果示意图

接收文本数据，并进行表格显示

接受文本数据，并进行图表显示

前台代码如下

    <Grid><TextBox x:Name="Tip" HorizontalAlignment="Left" Height="24" Margin="8,176,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Width="40" BorderBrush="{x:Null}" Background="{x:Null}" FontSize="16" IsReadOnly="True" Foreground="Black" HorizontalContentAlignment="Center" Text="提示"/><ComboBox x:Name="Port_Select" RenderTransformOrigin="1.436,2.058" BorderBrush="Black" Foreground="Black" FontFamily="Microsoft YaHei" Background="{x:Null}" Height="32" VerticalAlignment="Top" HorizontalAlignment="Left" Width="76" MouseEnter="PortSelect_MouseEnter" Margin="75,30,0,0" FontSize="13.333" VerticalContentAlignment="Center"/><Button x:Name="Port_Open" Content="打开串口" Margin="75,170,0,0" RenderTransformOrigin="-0.833,1.211" Click="PortOpen_Click" Background="{x:Null}" BorderBrush="Black" FontFamily="Microsoft YaHei" FontSize="16" HorizontalAlignment="Left" Width="76" Height="32" VerticalAlignment="Top"/><TextBox x:Name="textBox" HorizontalAlignment="Left" Height="300" Margin="186,36,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Width="396"/><GroupBox Header="接收数据" Height="326" HorizontalAlignment="Left" Margin="186,10,0,0" x:Name="GroupBox" VerticalAlignment="Top" Width="396"/><ComboBox x:Name="comboBox" HorizontalAlignment="Left" Margin="75,103,0,0" VerticalAlignment="Top" Width="76" Background="{x:Null}" Height="32" FontSize="13.333" VerticalContentAlignment="Center" ><ComboBoxItem Content="9600"/><ComboBoxItem Content="14400"/><ComboBoxItem Content="19200"/><ComboBoxItem Content="38400"/><ComboBoxItem Content="57600"/><ComboBoxItem Content="115200"/></ComboBox><TextBlock x:Name="textBlock" HorizontalAlignment="Left" Margin="8,36,0,0" VerticalAlignment="Top" RenderTransformOrigin="-0.673,-3.125" Height="24" Width="40" Text="端口" FontSize="16" LineHeight="8" TextWrapping="Wrap" TextAlignment="Center"/><TextBlock x:Name="textBlock1" HorizontalAlignment="Left" Margin="8,108,0,0" TextWrapping="Wrap" Text="波特率" VerticalAlignment="Top" Width="60" Height="28" FontSize="16"/><Button x:Name="clr" Content="clear" HorizontalAlignment="Left" Margin="8,240,0,0" VerticalAlignment="Top" Width="50" Click="Clr_Click" Height="28" FontSize="16" Background="{x:Null}"/><Button x:Name="chart" Content="chart" HorizontalAlignment="Left" Margin="100,240,0,0" VerticalAlignment="Top" Width="50" Click="Chart_Click" Height="28" Background="{x:Null}" FontSize="16"/><Button x:Name="table" Content="table" HorizontalAlignment="Left" Margin="100,300,0,0" VerticalAlignment="Top" Width="50" RenderTransformOrigin="0.037,-0.94" Height="28" Background="{x:Null}" FontSize="16" Click="Table_Click"/><Button x:Name="save" Content="save" HorizontalAlignment="Left" Margin="8,300,0,0" VerticalAlignment="Top" Width="50" Height="28" Background="{x:Null}" FontSize="16" Click="Save_Click"/></Grid>
