4.19 ZCD - Zero Cross Detector

4.19.1 Introduction

The MCC Melody Zero-Cross Detector (ZCD) PLIB Driver (Peripheral Library) generates APIs to support ZCD-specific peripheral functionality on AVRxxxDx target MCU's.

The ZCD module detects when an alternating voltage crosses through a threshold voltage, ZCPINV, near the ground potential.

4.19.2 Supported Device Families

AVR® Dx AVR® Ex

4.19.3 Required Header Files:

#include "mcc_generated_files/zcd/zcd[X].h"
Note: Replace [X] with selected instance of the ZCD module.
