lpadc_etc_hardware_trigger_conv

Overview

The adc_etc_hardware_trigger_conv example shows how to use the ADC_ETC to generate a ADC trigger by PIT channel0 trigger.

Every 1 second, PIT channel0 would send a trigger signal to ADC_ETC, which can arbitrate and manage multiple external triggers, and ADC_ETC would generate ADC trigger.

In this example, the ADC is configured with hardware trigger. Once ADC gets the trigger from the ADC_ETC, the conversion goes, then the ADC_ETC ISR would be executed.
