The uart_functioncal_interrupt example shows how to use uart driver functionalAPI to receive data with interrupt method:In this example, one uart instance connect to PC through uart, the board willsend back all characters that PC send to the board.

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

The uart_interrupt example shows how to use uart driver in interrupt way:In this example, one uart instance connect to PC through uart, the board willsend back all characters that PC send to the board.Note: The example echo every 8 characters, so input 8 characters every time.

The uart_polling example shows how to use uart driver in polling way:In this example, one uart instance connect to PC through uart, the board will send back all characters that PCsend to the board.

The WDOG8 Example project is to demonstrate usage of the wdog8 driver.In this example, fast testing is first implemented to test the wdog8.After this, refreshing the watchdog in None-window mode and window mode is executed.Note wdog8 is disabled in SystemInit function which means wdog8 is disabledafter chip emerges from reset.
