+/**
+ * @example ACKme_HelloWorld/main.cpp
+ *
+ * This example program verifies the operation of key features of the Nucleo board,
+ * without the ACKme shield installed. 
+ * It blinks the Nucleo board user LED, 
+ * It increases the blink rate when you press the User button. 
+ * It prints to a serial terminal connected to the USB port
+ * and echoes characters entered at the terminal.
+ * It responds, with a message, to typing 'hi <Enter>' at the terminal. 
+ *
