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_uart_edma_transfer example shows how to use uart cmsis driver with EDMA: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.

More information and usage methord please refer to http://www.keil.com/pack/doc/cmsis/Driver/html/index.html.The cmsis_uart_interrupt_transfer example shows how to use uart cmsis 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 COP Example project is to demonstrate usage of the KSDK cop driver.In this example, after 10 times of refreshing, a timeout reset is generated.Please notice that because COP control registers are write-once only, so the COP_Init function and the COP_Disable function can be called only once after reset.In SystemInit() function which is called in startup code, there is an operation to disable the watchdog if macro DISABLE_WDOG is defined as 0, and by default if the DISABLE_WDOG is not defined, the DISABLE_WDOG is defined as 1. So this example has a special project setting that defines the DISABLE_WDOG macro to 0 so the startup code will skip the disable COP WDOG operation.

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 DMA wrap transfer example is a simple demonstration program that uses the SDK software.It executes wrap 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 and to provide a simple example for debugging and further development.

The DMA memory to memory example is a simple demonstration program that uses the SDK software.It executes one shot 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 and to provide a simple example for debugging and further development.

The DMA ring buffer example is a simple demonstration program that uses the SDK software.It demostrates how to implement ring buffer using the SDK DMA drivers.The purpose of this example is to show how to use the DMA and to provide a simple example for debugging and further development.

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_i2c_read_accel_value example shows how to use FLEXIO I2C Master driver to communicate with an i2c device: 1. How to use the flexio i2c master driver to read a i2c device who_am_I register. 2. How to use the flexio i2c master driver to write/read the device registers.In this example, the values of three-axis accelerometer print to the serial terminal on PC throughthe virtual serial port on board.
