Mongoose OS driver for ADE7953

This is a driver for Analog Devices ADE7953.

Bus selection

Communication over I2C and SPI is supported, with I2C enabled by default. Bus support can be selected/deselected using defines:

cdefs:
  MGOS_ADE7953_ENABLE_SPI: 1
  MGOS_ADE7953_ENABLE_I2C: 0

Sensor details

The ADE7953 is a high accuracy electrical energy measurement IC intended for single phase applications. It measures line voltage and current and calculates active, reactive, and apparent energy, as well as instantaneous RMS voltage and current.

Example application

#include "mgos_ade7953.h"
