Flashing Keyboard lights as patterns
 

After putting the device into R&D 4-5 months ago, I got the idea of using the keyboard lights as a VU meter. Last week I started looking into it and came up with a flashing pattern (similar to Knight Rider, as lcuk likes to call it ;))

Here's the script for this pattern:

As it is, the above script is just for fun (won't do anything other than flashing the keyboard)

lcuk also pythonized it and added it to two apps, one is mostly just a proof of concept (should also play the Knight Rider music if you have mplayer installed)

.deb package: http://mohammadag.ucoz.com/maemo/kni...er_0.1_all.deb run it from terminal as root, by executing "python /opt/liqbase/KR/KR.py" (without the quotes)
.py file (for developers, it can be imported and used as a loading/busy indicator), by lcuk, http://mohammadag.ucoz.com/maemo/KR.py

Is it possible to tell the script to run e.g. 5 times in a row so it lasts a little longer?

yeah brog
thats easy
you see on the KR.py script it flashes a couple of times on startup

its simple to just adjust the loop and make it longer


i took this script and used it to make a 6key chord - pressing keys anywhere near the LED makes it light up and stay lit up indicating the mode.
turns the keyboard from 38 keys to 6

a bit of example code is posted here

Which reminds me, here's a manually made (yes, it was a pain) list of keycodes for the N900's QWERTY keymat - sorted by LEDs (which LED is closest to the key) (thanks go to qwerty12 for the xev binary)

This could be nice when playing emulators. Thinking of having only the keys lit that you use

Re: Flashing Keyboard lights as patterns
 

Can you point out where i can maybe slow it down a little

Re: Flashing Keyboard lights as patterns
 

rapparee - in the scripts there are pauses added by different means

bash
gsleep 0.05

python:
time.sleep(0.02)


alter as required

is it possible to make an app that wokrs with different patterns for

sms, mms, call, simple digits etc?

santiago - sure eventually i see that happening
it makes a really bright indicator for some things and its eye catching
however it only works when the keyboard is slid open for obvious reasons
