Introduction
The easy way to make a Green platform. The ODROID Smart Power is an easily deployable power supply that collects voltage, current and power of the system load to enable developers to optimize energy consumption. LCD shows voltage, current, watt and watt-hour(Wh) simultaneously. You can also see the graphical energy transient on your PC via USB interface.

Hardware
This file is the full schematics of ODROID Smart Power. http://dn.odroid.com/Smart_Power/PowerMeter20130624.pdf
PCI18F45K50 MCU data sheet : http://www.microchip.com/wwwproducts/Devices.aspx?dDocName=en558861
Can use the PICkit In-Circuit Debugger. See here for more information: http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1406&dDocName=en538340
Software
Cross Compiler
MPLAB C18 v3.43 or higher (From Microchip homepage : http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1406&dDocName=en010014&redirects=c18)
In my case, Standard-Eval Version (Free of Charge) was downloaded for my code optimization. It is the trial version and can only be used for 60 days.
IDE
X IDE v1.51 or higher (From Microchip homepage : http://www.microchip.com/pagehandler/en-us/family/mplabx )
How to write firmware
The firmware source code of ODROID Smart Power. http://dn.odroid.com/Smart_Power/smart_power_fw.zip
If you unzip the fw source code, there are two major directories.
Microchip : it contains the USB framework for firmware.
USB/Device - HID - Custom Demos/Firmware : it contains main firmware of Smart Power.
