Simple Hello World example for NXP LPCXpresso55S69 Development Board. This example prints "Hello World" and a counter value via the standard output which is routed to the debug console through Virtual COM port.

The following tools need to be installed on your machine:

• CMSIS-Toolbox v2.12.0 or newer.
• Arm Compiler for Embedded (automatically installed via vcpkg when using Visual Studio Code).
• Microsoft Visual Studio Code with Keil Studio Pack extension.
