The following applications are provided to demonstrate the typical or interesting usage
models of one or more peripheral libraries.
| Name | Description |
|---|---|
| AC PWM Generation | This example application shows how to use the Analog Comparator Peripheral library to generate a 1 kHz PWM waveform |
| AC Sleepwalking | This example application shows how to use the AC Peripheral library to perform a single shot comparison in standby sleep mode periodically and wake up the device at the end of a successful comparison |
| ADC Sample | This example application shows how to sample an analog input using the ADC and displays the converted samples on a serial terminal |
| ADC Window Sleepwalking | This application shows how to configure ADC in a sleepwalking operation, where input voltage is measured at a fixed interval, but device is not woken from sleep until the measured value is below a given threshold |
| Clock Configuration | This example application shows how to configure the clock system to run the device at maximum frequency. It also outputs a prescaled clock signal on a GPIO pin for measurement and verification |
| DAC Waveform Generation | This example application shows how to use the DAC to generate a 1 kHz Sine or Sawtooth wave with a look up table |
| DAC Waveform Generation with DMA | This example application shows how to use the DAC with the DMA to generate a 5 kHz sinusoidal waveform without CPU intervention |
