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!>
