According to the "Hello-world" example. The code use "UARTprintf" to send data to PC. BUT why there's only a USB emulator connection on the board rather than a serial connection? I am a total novice so I am confused.
Moreover, if I want to store the data, for example, the "helloworld" string into a database. What should I do in the PC program? Is there any API of the board that I can make use of? And which program language is the best to choose? VB or C#?
Thank you.
