bnf - battery information at glance 1.0
bnf - small nifty tool, displaying verbose battery-related info as pop-up notification
bnf is minimalistic, simple tool that display most important informations about battery and charging chip status (gathered via bq27x00_module, or i2cget), as notification pop-up message. It process values that need calculating and display them in human-readable format, detect state (charging via USB, wall charger, or discharging) and formatting visible info, accordingly.
It's main advantage, is that it displays info from last 5 seconds without influencing output by itself - It's possible to measure things like 3 mA power usage in echo > sys/power/mem state (via calling it as first thing upon wakeup).
bnf can be called via desktop icon (provided by package), terminal (sudo bnf), or things like shortcutd. Last one is extremely useful, as with bnf, it allows to check power usage, while inside full-screen programs, including OpenGLES applications (bnf can be called via camera button half-press), without connecting via ssh or running anything in background.
bnf works out-of-the box, and doesn't require any configuration.

Hello,
Thank you very much. bnf works well when I unload bq27x00_battery. Now I must find out what application is occupying the i2c. Could you give me any hint?
Please could you avoid syntax errors with something like attached patch.
See you.

# thanks to Nicolai, for teaching me about displaying output as notification.
# huge thanks shadowjk, I would not be able to get even close to starting this, without Your bq27200.sh state-of-art script.
It seems, that You have something occupying i2c exclusively - probably, module bq27x00_battery.ko loaded (either manually, or auto-loaded at boot). try to modprobe -r or rmod it, before.
Generally, it's not bnf "problem" (so thumb down isn't entirely justified) - although, I'll add warning to package description in new version.
