powertrace-help:
@echo Contiki powertrace is a tool that helps with collecting power data
@echo from motes. The data can be collected from a testbed or from a Cooja
@echo simulation. The powertrace data consists of lines of text that include
@echo the capital letter P followed by a list of numbers that contain the
@echo measured time that mote peripherals were switched on.
@echo
@echo A powertrace data file can be parsed and plotted with build-in
@echo powertrace scripts.
@echo
@echo To parse a data file with powertrace data, run:
@echo
@echo make powertrace-parse LOG=logfile
@echo
@echo to plot the parsed data, do:
@echo
@echo make powertrace-plot
@echo
@echo this produces two files called powertrace-power.eps and
@echo powertrace-node-power.eps. To show these files, run:
@echo
@echo make powertrace-show
@echo
@echo For convenience, all three above make targets can be combined into
@echo one:
@echo
@echo make powertrace-all LOG=logfile
@echo
