CMSIS-Driver defines generic peripheral driver interfaces for middleware making it reusable across a wide range of supported microcontroller devices. The API connects microcontroller peripherals with middleware that implements for example communication stacks, file systems, or graphic user interfaces. More information and usage methord please refer to http://www.keil.com/pack/doc/cmsis/Driver/html/index.html.The cmsis_i2c_dma_b2b_transfer_master example shows how to use i2c driver as master to do board to board transfer with DMA:In this example, one i2c instance as master and another i2c instance on the other board as slave. Master sends a piece of data to slave, and receive a piece of data from slave. This example checks if the data received from slave is correct.

More information and usage methord please refer to http://www.keil.com/pack/doc/cmsis/Driver/html/index.html.The cmsis_spi_dma_b2b_transfer_slave example shows how to use spi driver as master to do board to board transfer with DMA:In this example, one spi instance as master and another spi instance on the other board as slave. Master sends a piece of data to slave, and receive a piece of data from slave. This example checks if the data received from slave is correct.

More information and usage methord please refer to http://www.keil.com/pack/doc/cmsis/Driver/html/index.html.The cmsis_spi_interrupt_b2b_transfer_master example shows how to use CMSIS spi driver as master to do board to board transfer with interrupt:In this example, one spi instance as master and another spi instance on the other board as slave. Master sends a piece of data to slave, and receive a piece of data from slave. This example checks if the data received from slave is correct.

The CTimer Example project is to demonstrate usage of the KSDK ctimer driver.In this example, the match feature of the CTimer is used to toggle the output level.

The Simple Match Interrupt project is to demonstrate usage of the SDK CTimer driver with interrupt callback functionsIn this example the upon match and IO pin connected to the LED is toggled and the timer is reset, so it would generate a square wave.With an interrupt callback the match value is changed frequently in such a way that the frequency of the output square wave is increased gradually.

The DMA channel chain example is a simple demonstration program that uses the SDK software.The purpose of this example is to show how to use the DMA channel chain feature.

This example shows how to use DMA to transfer data from DMIC to memory.

The enet_rxtx_rxinterrupt example shows the simplest way to use ENET functional tx/rx API for simple frame receive and transmit.1. This example shows how to initialize the ENET.2. How to use ENET to receive frame in polling and to transmit frame.The example transmits 20 number broadcast frame, print the number and the mac address of the recieved frames.

The i2c_interrupt_b2b_transfer_master example shows how to use i2c driver as master to do board to board transfer with interrupt:In this example, one i2c instance as master and another i2c instance on the other board as slave. Master sends a piece of data to slave, and receive a piece of data from slave. This example checks if the data received from slave is correct.

The LED Blinky demo application provides a sanity check for the new SDK build environments and board bring up. The LED Blinky demo uses the systick interrupt to realize the function of timing delay. The example takes turns to shine the LED. The purpose of this demo is to provide a simple project for debugging and further development.
