JLINK RTT debugger support for rust

SEGGER RTT Support for Rust

This repo implements support for the Real Time Transfer (RTT) debugger extensions that are present in J-Link devices produced by SEGGER.

Using it

Basic logging:

extern crate jlink_rtt;

fn boo() {
   let mut output = jlink_rtt::Output::new();
   let _ = writeln!("Hello {}", 42);
}

Handling panics:

#![no_std]

extern crate panic_rtt;

fn main() {
    panic!("message is logged to debugger");
}
