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 methord please refer to http://www.keil.com/pack/doc/cmsis/Driver/html/index.html.The cmsis_i2c_edma_b2b_transfer_slave example shows how to use i2c driver as slave to do board to board transfer with a EDMA master:In this example, one i2c instance as slave and another i2c instance on the other board as master. 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.
