May I know how to use this nuget package "IS_nRF24l01p" . I have figured out the command and variable to be declared so that the device can use the NRF24L01p module. But as a beginner in coding, I dont really familiar with the syntax and so on. I just want to do a simple "Hello World". But I am stuck at the initialization step. I follow some tutorial from this website https://technoblogiot.wordpress.com/2016/12/27/raspberry-pi-et-le-controller-driver/ But it is in Vb. But I have to code in C#. Can anyone teach me on how to do the step like this? Declare the settings for nrf24L01. Thanks in advance.

All I have to do is to declare this in C#
Get started with UWP application template to create a simple UWP application.
Add a Setup() method and instance a nRF24L01P object and configure some settings.
In MainPage.xaml.cs the code will like this:
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);
}
}
Note: Above is answering your question simple because I don't know how InitNordicSPI implement (if it initialize the SPI and GPIO internally) so maybe you need initialize SPI and GPIO for interrupt by yourself.
