The ACMP Interrupt project is a simple demonstration program that uses the SDK software. Itcompares the selected analog input with ACMP internal DAC output continuously and toggle the LEDwhen the final comparison result changed. The purpose of this demo is to show how to use theACMP driver in SDK software by interrupt way. The ACMP can be configured based on defaultconfiguration returned by the API ACMP_GetDefaultConfig().

The ACMP Polling project is a simple demonstration program that uses the SDK software. It comparesthe selected analog input with ACMP internal DAC output continuously and toggle the LED when thefinal comparison result changed. The purpose of this demo is to show how to use the ACMP driverin SDK software by polling way. The ACMP can be configured based on default configuration returnedby the API ACMP_GetDefaultConfig().

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.

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 i2c_interrupt_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 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.

The spi_interrupt_b2b_transfer example shows how to use spi CMSIS driver in interrupt way:In this example , we need two boards, one board used as spi master and another board used as spi slave.The file 'spi_interrupt_b2b_transfer_master.c' includes the spi master code.This example uses the transactional API in spi driver.1. spi master send/received data to/from spi slave in interrupt .
