since my feeble attempts at asking this question in other contexts did not bring about any useful information and owing to kszaq 's mantra that separate threads for separate issues should be used, I open this one. Here is the problem:
I own the following box:
As you can see, there is an LCD panel in front which can show the time and connection status in Android - and which is completely dark in LE. Now, while I do not really need the clock functionality, the power indicator would be really nice to have and maybe some other indicator when the box is in standby.
For boxes that have just an led (blue/red), that works in LE as well and these can be triggered by echoing to whatever you find in /sys/class/leds. Does anyone have a clue whether anything similar is possible for the (elements of) the LCD panel? I believe that being able to access it would be quite an improvement.
