If done correctly, the virtual LED will blink. This is the foundation of the experience.

Use the UART component to send data from the STM32 to a Serial Monitor. If done correctly, the virtual LED will blink
Let's build a complete test environment to demonstrate "full" capabilities. We will simulate an STM32F407 controlling: Let's build a complete test environment to demonstrate
: Use the Serial Monitor component to debug UART data sent from the STM32 to a virtual terminal.
