2.6.4.7.1 Function adc_read_buffer_job()
Read multiple samples from ADC.
enum status_code adc_read_buffer_job( struct adc_module *const module_inst, uint16_t * buffer, uint16_t samples)
Read samples from the ADC into the buffer. If there is no hardware trigger defined (event action) the driver will retrigger the ADC conversion whenever a conversion is complete until samples has been acquired. To avoid jitter in the sampling frequency using an event trigger is advised.
