| Overview |
| ======== |
| The uart_interrupt_ring_buffer example shows how to use uart driver in interrupt way with |
| RX ring buffer enabled: |
| |
| In this example, one uart instance connect to PC through uart, the board will |
| send back all characters that PC send to the board. |
| |
| Note: The example echo every 8 characters, so input 8 characters every time. |

| Prepare the Demo |
| ================ |
| 1. Connect 12V power supply and J-Link Debug Probe to the board, switch SW701 to power on the board |
| 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. |
| Running the demo |
| ================ |
| When the demo runs successfully, the log would be seen on the debug terminal like: |
