我可以知道如何使用这个nuget包“IS_nRF24l01p”。我已经找到要声明的命令和变量，以便设备可以使用NRF24L01p模块。但作为编码的初学者，我真的不熟悉语法等等。我只想做一个简单的“Hello World”。但我陷入了初始化步骤。我按照这个网站上的一些教程https://technoblogiot.wordpress.com/2016/12/27/raspberry-pi-et-le-controller-driver/但它是在Vb。但我必须用C＃编写代码。任何人都可以教我如何做这样的步骤？声明nrf24L01的设置。提前致谢。

我所要做的就是在C＃中声明这一点
在MainPage.xaml.cs中，代码将如下所示：
public sealed partial class MainPage : Page
{
public MainPage()
{
this.InitializeComponent();
Setup();
}
public void Setup()
{
System.Diagnostics.Debug.WriteLine("Initialize MTPNordic");
IS_nRF24L01p.nRF24L01P nRf24 = new nRF24L01P();
// Use chip select line CS0; SPI speed set to 3 MHz; SPI0 CS0 is 8; Interrupt GPIO selected GPIO 5
nRf24.InitNordicSPI(new SpiConnectionSettings(0), 3000000, 8, 5);
}
}
注意：上面的问题很简单，因为我不知道InitNordicSPI是如何实现的（如果它在内部初始化SPI和GPIO），那么你可能需要自己初始化SPI和GPIO进行中断。
