How to Use
- First, you need to create a NRF24L01 object. After that you should call InitializeAsync() to initialize.
// 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();- Secondly
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);
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().
sender.Dispose();
receiver.Dispose();
