# Example usage
|
|
|
|
Below some really basic usage how I am ca using it:
|
|
|
|
```rust
|
|
let mut w5500: Option<W5500> = W5500::with_initialisation(
|
|
&mut cs_w5500, // borrowed for whole W5500 lifetime
|
|
&mut spi, // borrowed for call to `with_initialisation` only
|
|
OnWakeOnLan::Ignore,
|
|
OnPingRequest::Respond,
|
|
ConnectionType::Ethernet,
|
|
ArpResponses::Cache,
|
|
)
|
|
.ok();
|
|
|
|
let mut udp_server_socket: Option<UdpSocket> = w5500.as_mut().and_then(|w5500| {
|
|
let mut w5500: ActiveW5500<_> = w5500.activate(&mut spi).ok()?;
|
|
let socket0: UninitializedSocket = w5500.take_socket(Socket::Socket0)?;
|
|
(&mut w5500, socket0).try_into_udp_server_socket(1234).ok()
|
|
});
|
|
|
|
let mut buffer = [0u8; 256];
|
|
if let (Some(ref mut w5500), Some(ref socket)) = (
|
|
w5500.as_mut().and_then(w5500.activate(&mut spi).ok()),
|
|
udp_server_socket,
|
|
) {
|
|
if let Ok(Some((ip, port, len))) = (w5500, socket).receive(&mut buffer[..]) {
|
|
let (request_buffer, response_buffer) = buffer.split_mut_at(len);
|
|
|
|
// ... fill the response_buffer with some data ...
|
|
|
|
(w5500, socket).blocking_send(ip, port, response_buffer[..response_len]).unwrap();
|
|
}
|
|
}
|
|
```
