[Announce] saveCPU - overheating control for overclocked n900
 

I made ​​a script that controls the temperature through the bq27200 module and, if the n900 was overclocked, it reset the standard clock and turn on the LED.
The overclock will be automatically restored when the temperature drops 5 degrees Celsius below the alarm temperature.
A few weeks ago I added the ability to customize the script functions via UI.
Early versions were made ​​in Italian speak (safecpu at maemomeego.net, now SmartphoneTab.net). Now I add this version in English (packages have different names).

Through the graphical interface you can set:
- LED color
- activation temperature
- waiting time for each control
- enable / disable control

If enabled, the script will be launched each time the n900 starts.

Packages needed:
- Enhanced Linux kernel for power users
- Enhanced Linux kernel for power users (settings)
- i2c-tools instead bq27200 (implemetation by Peter Leinchen)

Package

p.s: sorry for my sucks English

thanx, but to what degree of accuracy are the cpu temperatures?

this must be excellent! let me try it and report back!

The temperature is not proper of the CPU because it is indicated by the bq27200 module, so it is not clear, but it is indicative.

Thanks. I was wondering.. How does the app know what the CPU's temperature is??

Read the previus post :)

Well I see that, but I was wondering if there was a temperature sensor on the CPU or something to do that.

Fantastic! I can now replace my crappy script with a neat looking GUI. Ottimo lavoro m750!

Sorry, I don't know :(

Nope. Our OMAP 3430 lacks a temperature sensor. Instead, there is a temperature sensor located near the battery, it can measure the battery's temperature in theory. Even though this might not be accurate, a battery temperature below 50 ^C is always good! :D
