AMB23 Realtek Standard SDK with Ameba RTL8722 UART Loopback Example

UART (Universal Asynchronous Receiver/Transmitter) is an useful peripheral that is very commonly found on various microcontrollers. It normally serves as a means to print out debug log for developer or even a way to upload new firmware into the non-volatile memory of the microcontroller. In this example, we will show you how to let Ameba RTL8722DM_MINI loopback the characters we entered through UART.
