One Phase power meter

MSP430EF4252 One Phase Energy Meter project

Similar projects worth following
I developed this project in 2014 for one customer.

This is one phase energy meter project for embedding into electric outlet.

Main controller MSP430FE4252 with built-in Energy meter module.

Display - graphical display 128x64 pixels - WX12864U-1
Because of 512Bytes of RAM and absence of reading graphic controller memory functionality I couldn't create normal graphical solution and Just added different font sizes support for text view.

Schematic is typical for that MCU, use DipTrace to open it.
Firmware is currently unavailable due to commercial reasons.

Voltage sensor - is resistors divider, current sensor - current transformer.
