为 Windows 10 IoT Core 使用 IS_Nrf24L01 nuget 包

Question

我可以知道如何使用这个 nuget 包 "IS_nRF24l01p" 。我已经弄清楚了要声明的命令和变量，以便设备可以使用 NRF24L01p 模块。但是作为编码的初学者，我对语法等并不是很熟悉。我只想做一个简单的“Hello World”。但我被困在初始化步骤。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中。但我必须用 C# 编写代码。 谁能教我如何做这样的步骤？声明 nrf24L01 的设置。提前致谢。

Answer 1

我所要做的就是在 C# 中声明它

1. Get started 使用 UWP 应用程序模板创建 a simple UWP application。

2. 添加一个 Setup() 方法并实例化一个 nRF24L01P 对象并配置一些设置。

在 MainPage.xaml.cs 中的代码如下：

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：上面回答你的问题很简单，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）所以也许你需要自己初始化 SPI 和 GPIO 以进行中断。
