Crate 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).

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.

• 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.
• eha1: Implements the aio::Registers trait for types in the eh1 module using the embedded-hal-async traits.
