Field Documentation

mutex

TX_MUTEX sf_audio_record_adc_instance_ctrl_t::mutex

Mutex used to protect access to lower level driver hardware registers

open

uint32_t sf_audio_record_adc_instance_ctrl_t::open

Used by driver to check if pointer to control block is valid

p_capture_data_buffer

void* sf_audio_record_adc_instance_ctrl_t::p_capture_data_buffer

Pointer to the buffer that will store the samples

sample_count

uint32_t sf_audio_record_adc_instance_ctrl_t::sample_count

Samples per channel to be buffered before notifying the app
