Usage

Add to the [dependencies] section in your Cargo.toml: rust stm32-eth = { version = "*", features = ["target-stm32f429"] }

In src/main.rs add: ```rust extern crate stm32f429 as target; use target::Peripherals;

extern crate stm32eth; use stm32eth::{Eth, RingEntry};

fn main() { let p = Peripherals::take().unwrap();

// Setup pins and initialize clocks.
eth::setup(&p);
// Allocate the ring buffers
let mut rx_ring: [RingEntry<_>; 8] = Default::default();
let mut tx_ring: [RingEntry<_>; 2] = Default::default();
// Instantiate driver
let mut eth = Eth::new(
    p.ETHERNET_MAC, p.ETHERNET_DMA,
    &mut rx_ring[..], &mut tx_ring[..]
);
// If you have a handler, enable interrupts
eth.enable_interrupt(&mut cp.NVIC);


if let Ok(pkt) = eth.recv_next() {
    // handle received pkt
}


eth.send(size, |buf| {
    // write up to `size` bytes into buf before it is being sent
}).expect("send");

} ```

[smoltcp] support

The master branch of stm32-eth contains support for the current master branch of the [smoltcp] TCP/IP stack. It has been removed for release because it is incompatible with latest [smoltcp] stable release 0.4.0.
