Arduino Due (Arm Cortex M3, 12-bit ADC) 3-Phase Example Library
Arduino Energy Monitoring Library - compatible with Arduino 1.0 part of openenergymonitor.org project
Based on emonLib: https://github.com/openenergymonitor/EmonLib Modifed for Arduino Due and 3 Phase by icboredman (boredman@boredomprojects.net) - Jan 2014
Download to Arduino IDE 'libraries' folder. Restart of IDE required.
- added 3-phase buffer-delay algorithm, when CT sensors connected to different line phases.
- also includes support for 12-bit ADC resolution on Arduino Due.
- Since it makes sense to keep main EmonLib library single phase, these files were renamed to "EmonLib_3PH.cpp" and "EmonLib_3PH.h"
Includes example sketch "ArduinoDue_3phase.ino" showing how to use Due as an EmonTx:
- There are 10 CT inputs connected to various household lines (after circuit breakers) and 1 AC-AC voltage adapter connected to one of these lines, used to measure voltage.
- 10 lines are connected to different phases, therefore, an extra parameter was added to functions voltage() and voltageTX() indicating a particular phase number.
- The AC-AC line voltage adapter must be connected to phase 1.
