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 lpi2c_int_b2b_transfer_master example shows how to use CMSIS i2c driver as master to do board to board transfer with interrupt:In this example, one lpi2c instance as master and another lpi2c 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 cmsis_lpspi_edma_b2b_transfer example shows how to use LPSPI CMSIS driver in edma way:In this example , we need two boards, one board used as LPSPI master and another board used as LPSPI slave.The file 'cmsis_lpspi_edma_b2b_transfer_master.c' includes the LPSPI master code.1. LPSPI master send/received data to/from LPSPI slave in edma .

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.

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 DAC / ADC demo application demonstrates the use of the DAC and ADC peripherals. This application demonstrates how toconfigure the DAC and set the output on the DAC. This demo also demonstrates how to configure the ADC in 'Blocking Mode'and how to read ADC values.

The dac_basic example shows how to use DAC module simply as the general DAC converter.When the DAC's buffer feature is not enabled, the first item of the buffer is used as the DAC output data register.The converter would always output the value of the first item. In this example, it gets the value from terminal,outputs the DAC output voltage through DAC output pin.
