Modifying led colours and patterns

There are multiple triggers for led blinking. All can be found in 

/etc/mce/mce.ini

The file can be edited with any text editor that can be run with Root access and open the file. So GUI - editors probably don't work, but terminal versions all will.

Step by step instructions

  • Open terminal
  • Gain Root access
  • Make a backup (not necessary!) from original mce.ini -file, for example: 
cp /etc/mce/mce.ini /etc/mce/mce.ini_old
  • Open /etc/mce/mce.ini with a text editor (nano, vim, leafpad...)
  • Search for a line: 
[LEDPatternLystiRX51]
  • Make your changes to the lines below
  • Save
  • Restart mce -process. Either reboot or type to terminal: 
initctl stop mce; sleep 2; initctl start mce

Constructing own patterns

The mce.ini -file has description header before pattern defining start. Here are the same instructions with longer explanations.

Example string: 

PatternCommunicationCall=30;1;0;r;9d80400002ff03ff02ff03ff71080000;9d800000


Dissection:

PatternCommunicationCall= 30; 1; 0; r; 9d80400002ff03ff02ff03ff71080000; 9d800000
Alert pattern priority screen on timeout led mapping Engine 1 pattern Engine 2 pattern


Priority

This defines that which blinking pattern is the strongest. So if multiple alerts are enabled, which pattern will be shown. Values from 0 to 255 are accepted.

Screen on

from mce.ini: 

0 only show pattern when the display is off
1 show pattern even when the display is on
2 only show pattern when the display is off, including acting dead
3 show pattern even when the display is on, including acting dead
4 only show pattern if the display is off, or if in acting dead
5 always show pattern, even if LED disabled

Timeout

Time in seconds after blinking is stopped. 0 = infinite blinking.

Led mapping

  • r/g/b maps led to engine 1,
  • R/G/B maps led to engine 2.

examples: 

rGB = red led is mapped to engine 1, green and blue to engine 2

rBg = red and green leds are mapped to engine 1, blue to engine 2.

You can of course define only one colour, for example: 

r = red led is mapped to engine

Engine patterns

from mce.ini: 

# 0000 -- Jump to the start of the pattern for the channel
# 40xx -- Set channel brightness
# 9d80 -- Refresh Mux (use as first command in every pattern!)
# xxyy -- Increment/decrement
#      xx determines the speed;
#         02-3f -- short step time (granularity 0.49ms)
#         42-7f -- long step time (granularity 15.6ms)
#
#	  If xx is even, increment
#         If xx is odd, decrement
#      yy determines the increment/decrement steps
#         00-ff -- in/decrement steps
#
#         Use 0 steps to create pauses
#         Two consecutive increment/decrement sequences are needed
#         to cover the entire range from 0-255
# c000 -- End pattern execution
# e002 -- Send engine 1 trigger
# e004 -- Send engine 2 trigger
# e008 -- Send engine 3 trigger <used by key backlight!>
# e080 -- Wait for engine 1 trigger
# e100 -- Wait for engine 2 trigger
# e200 -- Wait for engine 3 trigger <used by key backlight!>

Remote WLAN Access To Root / System Files

for easy file manipulation

(please note: all these apps and steps may not be necesarry but I got it working like this)

this help file assumes you know the risks and how to at least download and install apps from the extra repos..


i think you also need diablo_kernel_usbnet_patch_windows_v0.4 available here: https://garage.maemo.org/frs/?group_id=801



To get remote access to N900 thru wifi:

1. install the following apps/software


n900 end: (all these apps are in extras repos)

ssh server/client - this will request password when installing (WRITE DOWN / TAKE NOTE OF PASSWORD !!) rootsh maemo-pc-connectivity mad developer


for pc end:

winscp http://winscp.net/download/winscp425setup.exe


2. goto 'settings' > connectivity > 'pc-connectivity-manager'

3. click "advanced" button > select environment 'default'

4. select connectiont type 'usb'

5. options > select 'network' from drop-down list

6. select connectiont type 'internet' > options > connect using 'WLAN'

7. Save and apply

8. open "mad developer" > manage usb > 'gfile_storage' > close

9. open winscp and put the WLAN ip address shown in mad developer in the 'host name'

10. user name "root", password "(password created during ssh install)"

11. save > login

12. you should now have access!!
