The spi_polling_board2board_slave example shows how to use spi driver as slave to do board to board transfer withpolling:Notice: The SPI slave of this example uses interrupt mode, as there is no polling mode for SPI slave.In this example, one spi instance as slave and another spi instance on other board as master. Master sends a piece ofdata to slave, and receive a piece of data from slave. This example checks if the data received from master is correct.

The SPIFI DMA Example project is a demonstration program that uses the KSDK software to program external serialflash using DMA and read through AHB bus.

The SPIFI Polling Example project is a demonstration program that uses the KSDK software to program external serialflash using polling and read through AHB bus.

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 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 5 times of refreshing the watchdog, a timeout reset is generated.
