What Contains

In NRF24L01.cs file

代码语言:javascript复制
/// <summary>
/// Initialize
/// </summary>
public async Task InitializeAsync();

/// <summary>
/// Send
/// </summary>
/// <param name="data">Data</param>
public async void Send(byte[] data);

/// <summary>
/// Receive
/// </summary>
/// <param name="length">Packet Size</param>
/// <returns>Data</returns>
public byte[] Receive(byte length);

......

How to Use

  • First, you need to create a NRF24L01 object. After that you should call InitializeAsync() to initialize. ```C# // Create and Initialize // CSN Pin, CE Pin, IRQ Pin, SPI Friendly Name, Receive Packet Size NRF24L01 sender = new NRF24L01(0, 23, 24, "SPI0", 12); NRF24L01 receiver = new NRF24L01(0, 5, 6, "SPI1", 12);

await sender.InitializeAsync(); await receiver.InitializeAsync(); * SecondlyC# sender.Send(Encoding.UTF8.GetBytes("ZhangGaoxing")); receiver.ReceivedData = Receiver_ReceivedData;

private void Receiver_ReceivedData(object sender, ReceivedDataEventArgs e) { var raw = e.Data.Skip(1).ToArray(); var res = Encoding.UTF8.GetString(raw);

代码语言:javascript复制
Debug.Write("Received Raw Data : ");
foreach (var item in raw)
{
    Debug.Write($"{item} ");
}
Debug.WriteLine("");
Debug.WriteLine($"Received Data : {res}");

} * If you want to close the sensor, call Dispose().C# sender.Dispose(); receiver.Dispose(); ```
