adc_etc_software_trigger_conv#
Overview#
The adc_etc_software_trigger_conv example shows how to use the ADC_ETC to generate a ADC trigger by software 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.
