The adc_interrupt example shows how to use interrupt with adc driver.In this example, user should indicate a channel to provide a voltage signal (can be controlled by user) as the adc'ssample input. When running the project, typing any key into debug console would trigger the conversion. ADC interrupt would be asserted once the conversion is completed. In ADC ISR, the conversion completed flag would be cleared by reading the conversion result value. Also, the conversion result value is stored, and the ISR counter is increased. These information would be printed when the execution return to the main loop.The point is that the adc interrupt configuration is set when configuring the adc's conversion channel. When in software trigger mode, the conversion would be launched by the operation of configuring channel, just like writing aconversion command. So if user wants to generate the interrupt every time the conversion is completed, the channel's configuration with enabling interrupt setting would be used for each conversion.

The adc_polling example shows the simplest way to use adc driver.In this example, user should indicate a channel to provide a voltage signal (can be controlled by user) as the adc'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 adc's performance.

The adc_etc_software_trigger_conv example shows how to use the ADC_ETC to generate a ADC trigger by PIT channel0 trigger.Every 1 second, PIT channel0 would send a trigger signal to ADC_ETC, which can arbitrate and manage multiple external triggers,and ADC_ETC would generate ADC trigger.In this example, the ADC is configured with hardware trigger. Once ADC gets the trigger from the ADC_ETC, the conversion goes,then the ADC_ETC ISR would be executed.

The cache example shows how to use memory cache driver.In this example, many memory (such as SDRAM, etc) and DMA will be used to show the example.Those memory is both accessible for cpu and DMA. For the memory data alignment, cache driver should be used rightly. For cache enabled case, the cache invalidate operation should be done before cpu access the memory. The cache clean opeartion should be done after CPU verify the memorymemory and before DMA access the memory.

The ccm_clockout driver example shows how to output the internal clock signal. In this driver example, users can choose the clock signal to be outputted, and the divider of the output clock signal. By probing the output pin, users can observe the selected internal clock signal.

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.
