The ADC16 continuous EDMA demo application demonstrates the usage of the ADC and EDMA peripheral while in a continuous mode. TheADC16 is first set to continuous mode. In continuous convert configuration, only the initial rising-edge to launch continuous conversions isobserved, and until conversion is aborted, the ADC16 continues to do conversions on the same SCn register that initiated the conversion. EDMA request will be asserted during an ADC16 conversion complete event noted when any of the SC1n[COCO] flags is asserted. EDMA will transferADC16 results to memory and if users press any key, demo will average ADC16 results stored in memory and print average on the terminal.

The ADC Low Power Async DMA demo application demonstrates the usage of the ADC and DMA peripheral while in a low power mode. Themicrocontroller is first set to very low power stop (VLPS) mode. Every 100 ms, low power timer trigger the ADC module convertvalue on ADC channel. After 16 times(1,6s) the DMA transfer finish interrupt wake up the CPU to process sampled data, print result touser and toggle LED.

The adc16_polling example shows the simplest way to use ADC16 driver.In this example, user should indicate a channel to provide a voltage signal (can be controlled by user) as the ADC16'ssample input. When running the project, typing any key into debug console would trigger the conversion. The execution would check the conversion completed flag in loop until the flag is asserted, which means the conversion is completed. Then read the conversion result value and print it to debug console.Note, the default setting of initialization for the ADC converter is just an available configuration. User can changethe configuration structure's setting in application to fit the special requirement.The auto-calibration is not essential but strongly recommended. It can help to adjust the converter itself and improvethe ADC16's performance.

The ADC potentiometer demo application demonstrates how to read the analog value from a hardware potentiometer via theADC peripheral.

The CMP polling Example shows the simplest way to use CMP driver and help user with a quick start.In this example, user should indicate an input channel to capture a voltage signal (can be controlled by user) as the CMP's positive channel input. On the negative side, the internal 6-bit DAC is used to generate the fixed voltage abouthalf value of reference voltage.When running the project, change the input voltage of user-defined channel, then the comparator's output would changebetween logic one and zero when the user's voltage crosses the internal DAC's value. The endless loop in main() functionwould detect the logic value of comparator's output, and change the LED. The LED would be turned on when the compareoutput is logic one, or turned off when zero.

The dspi_edma_b2b_transfer example shows how to use DSPI CMSIS driver in edma way:In this example , we need two boards, one board used as DSPI master and another board used as DSPI slave.The file 'dspi_edma_b2b_transfer_master.c' includes the DSPI master code.1. DSPI master send/received data to/from DSPI slave in edma .

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_edma_b2b_transfer_master example shows how to use i2c driver as master to do board to board transfer with EDMA: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.
