Halting the attached chip

# use probe_rs::Error;
use probe_rs::{Probe, Permissions};

// Get a list of all available debug probes.
let probes = Probe::list_all();

// Use the first probe found.
let mut probe = probes[0].open()?;

// Attach to a chip.
let mut session = probe.attach("nrf52", Permissions::default())?;

// Select a core.
let mut core = session.core(0)?;

// Halt the attached core.
# Ok::<(), Error>(())

Reading from RAM

# use probe_rs::Error;
use probe_rs::{Session, Permissions};
use probe_rs::MemoryInterface;

let mut session = Session::auto_attach("nrf52", Permissions::default())?;
let mut core = session.core(0)?;

// Read a block of 50 32 bit words.
let mut buff = [0u32;50];
core.read_32(0x2000_0000, &mut buff)?;

// Read a single 32 bit word.
let word = core.read_word_32(0x2000_0000)?;

// Writing is just as simple.
let buff = [0u32;50];
core.write_32(0x2000_0000, &buff)?;

// of course we can also write 8bit words.
let buff = [0u8;50];
core.write_8(0x2000_0000, &buff)?;

# Ok::<(), Error>(())

probe-rs is built around 5 main interfaces: the [Probe], [Target], [Session], [Memory] and [Core] strucs.
