# MPLAB® Harmony 3 Class B Library for SAM E5x/D5x Devices

MPLAB® Harmony 3 is an extension of the MPLAB® ecosystem for creating embedded firmware solutions for Microchip 32-bit SAM and PIC® microcontroller and microprocessor devices.  Refer to the following links for more information.

- [Microchip 32-bit MCUs](https://www.microchip.com/design-centers/32-bit)
- [Microchip 32-bit MPUs](https://www.microchip.com/design-centers/32-bit-mpus)
- [Microchip MPLAB X IDE](https://www.microchip.com/mplab/mplab-x-ide)
- [Microchip MPLAB® Harmony](https://www.microchip.com/mplab/mplab-harmony)
- [Microchip MPLAB® Harmony Pages](https://microchip-mplab-harmony.github.io/)

This repository contains the MPLAB® Harmony 3 Class B Library which implements several test and diagnostic methods that support the IEC 60730 standard for the safe operation of an electronically controlled equipment for household use.
Annex H of the IEC 60730 standard defines ‘Class B’ software. The Class B Library available in MPLAB® Harmony 3 implements several test and diagnostic methods that fall into the Class B category.
It uses various measures to detect and respond to failures inside the microcontroller which can result in an unsafe state of the appliance.
