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.

The CRC Example project is a demonstration program that uses the KSDK software to generate checksumsfor an ASCII string. Several CRC protocols are implemented using the CRC driver API.

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 CTimer Example project is to demonstrate usage of the KSDK ctimer driver.In this example, CTimer is used to generate a PWM signal.

The Simple PWM Interrupt project is to demonstrate usage of the SDK CTimer driver as a PWM with interrupt callback functionsIn this example an IO pin connected to the LED is used as a PWM output line to generate a PWM signal.With an interrupt callback the PWM duty cycle is changed frequently in such a way that the LED brightness can be varied.

The DMA interleave transfer example is a simple demonstration program that uses the SDK software.It executes a linked transfer from source buffer to destination buffer using the SDK DMA drivers.The purpose of this example is to show how to use the DMA interleave feature.
