The EDMA memory to memory example is a simple demonstration program that uses the SDK software.It excuates one shot transfer from source buffer to destination buffer using the SDK EDMA drivers.The purpose of this example is to show how to use the EDMA and to provide a simple example fordebugging and further development.

The EWM Example project is to demonstrate usage of the KSDK EWM driver.In the example, EWM counter is continuously refreshed until button is pressed.Once the button is pressed, EWM counter will expire and interrupt will be generated.After the first pressing, another interrupt can be triggered by pressing button again.

The flexio_i2c_interrupt example shows how to use flexio i2c master driver in interrupt way:In this example, a flexio simulated i2c master connect to an I2C slave.

The FlexIO MCU LCD demo application demonstrates how to use SDK FlexIO to driveMCU interface LCD.The example displays one picture and an arrow at the right bottom of the screen.When press the arrow, a new picture is shown.The project has provide the source code of the pictures (pictures.c), you canmodify and re-generate the pictures.bin. For example, the pictures.bin could begenerated using armgcc commands:~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~arm-none-eabi-gcc -c pictures.c -DBUILD_PIC_BINarm-none-eabi-objdump -O binary pictures.o pictures.bin~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This demo describes how to use SDK drivers to implement the PWM feature by FLEXIO IP module. It outputs the PWM singal with fixed frequency defined by "DEMO_FLEXIO_FREQUENCY" in source code and dynamic duty from 99 to 1 to one of the FLEXIO pin.

The flexio_spi_master_edma_dspi_slave example shows how to use flexio spi master driver in edma way:In this example, a flexio simulated master connect to a dspi slave .

The flexio_spi_slave_edma_dspi_master example shows how to use flexio spi slave driver in dma way:In this example, a flexio simulated slave connect to a dspi master.

The flexio_spi_master_interrupt_dspi_slave example shows how to use flexio spi master driver in interrupt way:In this example, a flexio simulated master connect to a dspi slave .

The flexio_spi_slave_interrupt_dspi_master example shows how to use flexio spi slave driver in interrupt way:In this example, a flexio simulated slave connect to a dspi master.

The flexio_uart_edma example shows how to use flexio uart driver in edma way:In this example, a flexio simulated uart connect to PC through USB-Serial, the board will send back all charactersthat PC send to the board.
