EVAL-ADE7913 no-OS Project

Contents

Supported Evaluation Boards

  • EVAL-ADE7913

Overview

The EVAL-ADE7913 provides a complete evaluation platform for the ADE7913 isolated sigma-delta ADC, enabling the prototyping, testing, and assessment of high-performance energy metering systems in realistic three-phase meter scenarios. The platform integrates hardware-specific configurations and interfaces—including SPI, UART, GPIO, and NVIC interrupt management—with robust application logic to demonstrate features such as dynamic RMS computation, burst mode read operations, and synchronized multi-device operations.

Applications

  • Shunt-based polyphase meters

  • Power quality monitoring

  • Solar inverters

  • Process monitoring

  • Protective devices

  • Isolated sensor interfaces

  • Industrial PLCs

No-OS Supported Examples

The initialization data used in the example is sourced from the Project Common Data Path. The macros used in Common Data are defined in platform-specific files found in: Project Platform Configuration Path.

ADE7913 Evaluation Example

The ADE7913 example project demonstrates how to initialize and communicate with ADE7913 devices using no-OS drivers. It covers hardware interface initialization, interrupt management, and data processing, and it showcases key functionalities such as SPI and GPIO configuration.

The ADE7913 evaluation example is selected via the ade7913_example build variant (see the Build Command section below).
