HI...
here is the basic UART project that transmits the message on the terminal. Would also like to highlight that this example is exactly the same as one provided inside of XMCLib package under XMC4500 series/UART/UART_TRANSMIT example. I´ve just changed the LED define while it´s connected to different pin.
Best regards,
Deni
