Actually I do not why there are three arguments in open(), but it do not work without the last 1. I take that on this page: http://wiki.openmoko.org/wiki/Vibrator >I don't get the purpose of writing numbers to the file? This is not a normal file.

I have never hearded about this file, until this messagechain, so I ask the current value of it cat /sys/devices/platform/s3c2440-i2c/i2c-adapter/i2c-0/0-0073/backlight/pcf50633-bl/brightness And it said 63. I wanted it more bright so I tried echo 64 > /sys/devices/platform/s3c2440-i2c/i2c-adapter/i2c-0/0-0073/backlight/pcf50633-bl/brightness And it said: echo: write error: Invalid argument So I thought maybe 63 is the maximum value. And surprisingly sametime in devel-list I got verification and much more: http://lists.openmoko.org/nabble.html#nabble-td726729 If you are interested in other device-files, there are some list (not complete): http://wiki.openmoko.org/wiki/GTA02_sysfs -Aapo Rantalainen ___ support mailing list support@lists.openmoko.org https://lists.openmoko.org/mailman/listinfo/support
Re: Application to fade screen
Wow this is great thanks aapo! I was actually thinking about just writing a
shell script to echo 0 into that file but I like this way alot better. Do
you think you could walk me through the python script? I'm not much of a
python guru and already I can't find out why open() has a third argument.
I'm only used to seeing two and searching open for 3 arguments comes up with
nothing. I don't get the purpose of writing numbers to the file? Do the
numbers control how much it fades? and what is 63 for? Where did you find
out about '/*
sys/devices/platform/s3c2440-i2c/i2c-adapter/i2c-0/0-0073/backlight/pcf50633-bl/brightness'
* ? Thanks again for all your help!

I think best way to tell something is use shell. This is some python
application to fade screen black and light again. This is not screen
saver, there is no input reading etc. This is only my way to say how
shell -> python (or if you can write in file with java, then shell ->
java)
Should this be in wiki? And what is the right page?
#!/usr/bin/python

brig =

Re: Application to fade screen
haha no. I mean, is there some way to control it within in application? In like say C, python, or java? Not on a shell? Thanks!
