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.

In this example, the adc16 module is initiealized and used to measure the VREF output voltage. So, it cannot use interal VREF as the reference voltage. Then, user should configure the VREF output pin as the ADC16's sample input. When running the project, it will firstly measure the VREF output voltage within the default (factory) trim value. Then, it will measure the VREF output voltage under different trim value.

The WDOG Example project is to demonstrate usage of the KSDK wdog driver.In this example,quick test is first implemented to test the wdog.And then after 10 times of refreshing the watchdog in None-window mode, a timeout reset is generated.We also try to refresh out of window to trigger reset after 10 times of refreshing in Window mode.
