    The adc16_interrupt example shows how to use interrupt with ADC16 driver.In this example, user should indicate a channel to provide a voltage signal (can be controlled by user) as the ADC16'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 ADC16 interrupt configuration is set when configuring the ADC16'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.

    µVision AC6

    The ADC Low Power Async DMA demo application demonstrates the usage of the ADC and DMA peripheral while in a low power mode. Themicrocontroller is first set to very low power stop (VLPS) mode. Every 100 ms, low power timer trigger the ADC module convertvalue on ADC channel. After 16 times(1,6s) the DMA transfer finish interrupt wake up the CPU to process sampled data, print result touser and toggle LED.

  • adc16_low_power_peripheral

    µVision AC6

    The ADC Low Power demo application demonstrates the usage of the ADC peripheral while in a low power mode. Themicrocontroller is first set to very low power stop (VLPS) mode. Every 500 ms, an interrupt wakes up the ADC module andreads the current temperature of the microcontroller. While the temperature remains within boundaries, both LEDs are on.If the core temperature is higher or lower than average, the LEDs change state respectively. You can open the mex file with MCUXpresso Config Tool to do further configuration of pin, clock and peripheral.

    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_i2c_int_b2b_transfer_master

    µVision AC6

    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.
