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 default configuration is: highspeed is not enabled, invert output is not enabled, unfiltered output is not enabled, pin outis not enabled, offset level is level 0, hysteresis level is level 0.

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 default configuration is: high speed is not enabled, invertoutput is not enabled, unfiltered output is not enabled, pin out is not enabled, offset level islevel 0, hysteresis level is level 0.

The ACMP Round-Robin project is a simple demonstration program that uses the SDK software. Usermust set the round-robin mode trigger in specific board properly according to the board resourcebefore running the example. When the example running, it sets positive port as fixed channel andinternal DAC output as comparison reference in positive port and sets the channels input by useras round-robin checker channel. The example will enter stop mode and wait user to change the voltageof round-robin checker channel. It will exit stop mode after the voltage of round-robin checkerchannel changed by user.

The ADC12 continuous EDMA demo application demonstrates the usage of the ADC and EDMA peripheral while in a continuous mode. TheADC12 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 ADC12 continues to do conversions on the same SCn register that initiated the conversion. EDMA request will be asserted during an ADC12 conversion complete event noted when any of the SC1n[COCO] flags is asserted. EDMA will transferADC12 results to memory and if users press any key, demo will average ADC12 results stored in memory and print average on the terminal.

The adc12_interrupt example shows how to use interrupt with ADC12 driver.In this example, user should indicate a channel to provide a voltage signal (can be controlled by user) as the ADC12's sample 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 ADC12 interrupt configuration is set when configuring the ADC12's conversion channel. When in software trigger mode, the conversion would be launched by the operation of configuring channel, just like writing a conversion 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 Low Power Demo project is a demonstration program that uses the KSDK software. Themicrocontroller is set to a very low power stop (VLPS) mode, and every 500 ms an interrupt wakes upthe ADC module and takes the current temperature sensor value of the microcontroller. While the temperature remains within boundaries, both LEDs are on. If the temperature is higher or lower thanaverage, a led comes off. This demo provides an example to show how ADC works during a VLPS mode anda simple debugging.

The adc12_lpit_trgmux example shows how to use the LPIT and TRGMUX to generate a ADC trigger.In this example, user should indicate a channel to provide a voltage signal (can be controlled by user) as the ADC12'ssample input. When run the example, the ADC is triggered by TRGMUX and gets the ADC conversion result in the ADCConversion Complete (COCO) Interrupt. The LPIT is configured as periodic counter which will output pre-trigger andtigger signal to TRGMUX periodically.

The adc12_polling example shows the simplest way to use ADC12 driver.In this example, user should indicate a channel to provide a voltage signal (can be controlled by user) as the ADC12's sample 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 change theconfiguration 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 improve theADC12's performance.
