# Three-Phase Electricity Meter Firmware Project

## Project Overview
This project implements firmware for a three-phase electricity meter based on the RN831x chip, supporting communication protocols such as DL/T645-2007. The firmware includes core functional modules for energy metering, event logging, data freezing, and security authentication.

## Main Features
- Energy Metering: Accurate measurement of active/reactive energy, voltage, current, power, and other parameters
- Communication Protocols: Implementation of DL/T645-2007 and DL/T698 communication protocols
- Security Authentication: Support for ESAM module and security authentication functions
- Event Logging: Records abnormal events in the power system (e.g., overvoltage, undervoltage, overcurrent)
- Data Freezing: Supports scheduled and immediate freezing of meter data
- Parameter Configuration: Provides read/write operations for meter configuration parameters
- Data Storage: Manages data storage in EEPROM and Flash memory
