Thanks Kolja, I am a newbie to the device drivers, and will have a look at sysfs. I want to implement this at the kernel space not at the user sapce. First I thought I would test with the emulator and then test it on my android (S I9000). It can be tested on the emulator right? Also can you point to any reference material? What I need is to access the accelerometer and read the value but it must not block the android sensor API either.
