//! Sends "Hello, world!" through the ITM port 0
//!
//! **NOTE** Not all Cortex-M chips support ITM. You'll have to connect your
//! microcontroller's SWO pin to the debug interface. Some development boards
//! don't provide this option.
//!
//! This is faster than using semihosting.
//!
//! You'll need [`itmdump`] to receive the message plus you'll need to enable
//! OpenOCD's ITM support in `.gdbinit`.
