A Java program that dynamically shows FPS, CPU/GPU frequency and power of Odroid-XU.
If not disabled, GUI charts will be shown and updated dynamically.
##Usage
Go to Settings -> Developer Options. Enable "Show CPU usage" option.
java -jar powermeasure.jar [n] [-freq] [-fps] [-power] [-chart] [extpower:(com port name)]
n: number of samples to take at once/second (>=0)"
-freq: Don't poll for frequency
-fps: Don't poll for FPS
-util: Don't poll for utilisation
-power: Don't poll for power
-chart: Don't show chart
extpower:(com port name) : Read external system power from COM Port. Requires power poll to be active
Outputs current power usage in watts and final total power use in Joules. Current FPS is shown. Current utilisation is shown. At the end, average FPS, minimum, maximum and standard deviation are shown.
##Sampling rate Sample rate is 1/second.
##Dependencies
The adb shell command.
