Many of today micro-controllers circuit were developed for battery operation.
It is a hard task to debug the product for power consumption.
My idea is to develop a low cost power debugger - an electronic measuring system (software & hardware),a combination of a current sense power meter and analyzing software who can pin point the current consumption element in the design - whether it is hardware (static current) or software (who activate a hardware element).
The power debugger will use a a small micro controller as a data logger/sampler,and PC computer as a process & display element.
The PC software will display a real time graph of the HUT (hardware under test)power consumption including peak power,average and calculated time of life for the HUT.
Data can be stored in a file and the test result can be used as reliability test for the product lifetime of operation.
I am all ready start working on a design of the described low cost system - hopefully to have a test system that cost between 100~200 USD.
