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.

The CMP interrupt Example shows how to use interrupt with CMP driver.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-defined channel's voltage crosses the internal DAC's value. The change ofcomparator's output would generate the falling and rising edge events with their interrupts enabled. When any CMP interrupt happens, the CMP's ISR would turn on the LED light if detecting the output's rising edge, or turn off it whendetecting the output's falling edge.

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.

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 method please refer to http://www.keil.com/pack/doc/cmsis/Driver/html/index.html. The cmsis_enet_transfer example shows how to use CMSIS ENET driver: In this example, the ENET transmits 20 number broadcast frames and will print the received frame.
