| Overview |
| ======== |
| The Hello World demo application provides a sanity check for the new SDK build environments and board bring up. The Hello |
| World demo prints the "Hello World" string to the terminal using the SDK UART drivers. The purpose of this demo is to |
| show how to use the UART, and to provide a simple project for debugging and further development. |
| Note: Please input one character at a time. If you input too many characters each time, the receiver may overflow |
| because the low level UART uses simple polling way for receiving. If you want to try inputting many characters each time, |
| just define DEBUG_CONSOLE_TRANSFER_NON_BLOCKING in your project to use the advanced debug console utility. |

| 2. Connect a USB cable between the host PC and the J1701 USB port on the target board. |
| 3. Open a serial terminal with the following settings: |
| - 115200 baud rate |
| - 8 data bits |
| - No parity |
| - One stop bit |
| - No flow control |
| 4. Download the program to the target board. |
| 5. Launch the debugger in your IDE to begin running the demo. |
