Usage

Add to the [dependencies] section in your Cargo.toml: rust stm32f4xx-hal = { version = "*", features = ["stm32f429"] } stm32-eth = { version = "0.1.0", feautes = ["nucleo-f429zi"] }

In src/main.rs add: ```rust use stm32f4xxhal::{ gpio::GpioExt, stm32::Peripherals, }; use stm32eth::{Eth, RingEntry};

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

// Setup pins and initialize clocks.
stm32_eth::setup(&p.RCC, &p.SYSCFG);
let gpioa = p.GPIOA.split();
let gpiob = p.GPIOB.split();
let gpioc = p.GPIOC.split();
let gpiog = p.GPIOG.split();
stm32_eth::setup_pins(
    gpioa.pa1, gpioa.pa2, gpioa.pa7, gpiob.pb13, gpioc.pc1,
    gpioc.pc4, gpioc.pc5, gpiog.pg11, gpiog.pg13
);
// 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");

} ```
