w5500-ll

Platform agnostic rust driver for the [Wiznet W5500] SPI internet offload chip.

This is a low-level (ll) crate. The scope of this crate is: 1) Register accessors. 2) Networking data types.

Higher level functionality (such as socket operations) should be built on-top of what is provided here.

Example

Reading the VERSIONR register (a constant value).

```rust use w5500_ll::{eh1::vdm::W5500, Registers};

let mut w5500 = W5500::new(spi); let version: u8 = w5500.version()?; assert_eq!(version, 0x04); ```

Feature Flags

All features are disabled by default.

• async: Nightly only. Enables the asynchronous [aio::Registers] trait.
• defmt: Enable formatting most types with defmt.
• eh0: Enables the [eh0] module which contains implementations of the [Registers] trait using the embedded-hal version 0.2 traits.
• eh1: Enables the [eh1] module which contains implementations of the [Registers] trait using the embedded-hal version 1 traits.
• eha0a: Nightly only. Implements the [aio::Registers] trait for types in the [eh1] module using the embedded-hal-async alpha traits.
• ip_in_core: Nightly only. Use core::net types for Ipv4Addr and SocketAddrV4.
• std: Enables conversion between [std::net] and [w5500_ll::net] types. This is for testing purposes only, the std flag will not work on embedded systems because it uses the standard library.
