// Semihosting $(shortChipFamily) led blink sample (trace via $(trace)).
//
// In debug configurations, demonstrate how to print a greeting message
// on the trace device. In release configurations the message is
// simply discarded.
//
// To demonstrate semihosting, display a message on the standard output
// and another message on the standard error.
//
// Then demonstrates how to blink a led with 1 Hz, using a
// continuous loop and SysTick delays.
//
// On DEBUG, the uptime in seconds is also displayed on the trace device.
