Overview
The lpuart_polling Example project is to demonstrate usage of the KSDK lpuart driver. In the example, you can send characters to the console back and they will be printed out onto console instantly. Note: Please input one character at a time. If you input too many characters each time, the receiver may overflow because the LPUART uses simple polling way for receiving.

Prepare the Demo
- Connect a USB cable between the host PC and the OpenSDA USB port on the target board.
- Open a serial terminal with the following settings:
- 115200 baud rate
- 8 data bits
- No parity
- One stop bit
- No flow control
- Download the program to the target board.
- Either press the reset button on your board or 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 OpenSDA terminal like:

Board will send back received characters
Note: To debug in qspiflash, following steps are needed:
- Select the flash target and compile.
- Set the SW8: 1 off 2 off 3 on 4 off, then power on the board and connect USB cable to J23.
- Start debugging in IDE.
- Keil: Click "Download (F8)" to program the image to qspiflash first then clicking "Start/Stop Debug Session (Ctrl+F5)" to start debugging.
