Energy library follows an architecture which allows configuring settings from TI SysConfig, which makes managing the hardware settings quite easy for the user.

The energy library consists of three modules:

1. HAL Module

HAL Module is an abstraction layer that provides APIs to configure different pins and peripherals. The goal of using HAL is to abstract all device specific configuration which simplifies porting of the library to various hardware by minimizing the updates needed to other components.

2. ADS Module

The ADS module contains APIs to configure the ADS register, APIs to communicate through SPI and DMA. This module helps to reduce the code size when using multiple ADS modules in different applications.

3. Metrology Module

The metrology module is developed to process the sampled data and compute various metrology parameters for energy measurement. These parameters are collected by the calibration GUI for display

4. DLT645 Module

This is a communication module used to monitor the metrology parameters on GUI, the same GUI can be used to calibrate the meter parameters.
