Software description

SCIMO supports two different modes of operation:

• Ambient-Light mode
• MoodLight mode

Ambient-Light mode
SCIMO uses video input signal, either S-Video or Composite signal, to analyze video data. Depending on video image for every zone (LED) a suitable color is calculated and refreshed in realtime with 50/60 fps (frames per second). For this mode SCIMO offers some parameters to adjust Ambient-Light effects to personal feeling (e.g. to get more smooth or exciting color effects...).

 

MoodLight mode

In this mode none of the input signals is used and SCIMO generates some different light effects which can be choosen by IR remote control.

IR remote control

I recommend to use universal IR remote control URC-3920 or URC-7120 from company One for All. Functions of SCIMO are optimized to keyboard layout of this remote control.

IR remote control from company "One for All" and suitable device codes:

RC Type	parameter "IR_CODE_SET" in config file	device code
URC-3920 R02	2	11423
	1	11508
URC-3920 R03	0	1423
	1	1508
URC-7120	0	1423
	1	1508

Software configuration:

 

SCIMO can be configured via USB Interface connected to PC, it will appear as an USB mass strorage drive containing a configuration file named "config1.ini". In this text file (can be opend and edited with simple text editor) you will find some configuration points which are explained in the table below.

You can add an additional configuration file by simply copy file "config1.ini" and rename it to "config2.ini". SCIMO supports up to six different configurations files which are selectable by remote control with numeric buttons 1 - 6. This allows you to create different configuration profiles to match special needs (like different input sources selectable by remote control).

SCIMO do remember last selected configuration file and use it again at next power on. During boot-up procedure it shows which configuration file are used by flashing green onboard LED (video state). For example: if "config3.ini" has been selected than SCIMO will flash onboard LED three times with green light during boot-up procedure.

 

Available parameter for configuration:

parameter name	default value	example	possible values	description
LEDS_LEFT	15	[LEDS_LEFT] Val=15	0 - 70 (max. 240 overall LEDs)	Number of LEDs on left side of TV (seen from front view).
LEDS_RIGHT	15	[LEDS_RIGHT] Val=15	0 - 70 (max. 240 overall LEDs)	Number of LEDs on right side of TV (seen from front view).
LEDS_UPPER	30	[LEDS_UPPER] Val=30	0 - 90 (max. 240 overall LEDs)	Number of LEDs on upper side of TV.
LEDS_LOWER	30	[LEDS_LOWER] Val=30	0 - 90 (max. 240 overall LEDs)	Number of LEDs on lower side of TV.
TV_DELAY	0	[TV_DELAY] Val=0	0 - 400 ms (in steps of 20ms)	Adjustable delay for LED data output. By this parameter a possible display input lag of your TV can be compensated.
GammaCorrection	1.9	[GammaCorrection] Val=1.9	0.50 - 5.00	This value has big influence on Ambient-Light behavior, a lower value (e.g. "1.6") has the effect of smoother color mixing and is more relaxed for eyes. A bigger value (e.g. "2.2") gives more exciting color effects with sharper and saturated colors, which is for example nice at action games. This value has also big influence on color matching to TV. This parameter can be also adjusted during runtime with IR remote control.
Color_Averaging	2.0	[Color_Averaging] Val=2.0	0.0 - 20.0 (0 = no averaging)	By increasing this parameter a more averaged color mixing (averaged over time) is output to LEDs.
BrightnessMin	1.0	[BrightnessMin] Val=1.0	0 - 100 %	LEDs won't set darker than this value, helps to keep a minimum of brightness from back of TV which is more relaxed for eyes.
BrightnessMax	100.0	[BrightnessMax] Val=100.0	0 - 100 %	LEDs won't set brighter than this value, usefull if LED stripes equipped with very bright LEDs.
RedCorrection	1.00	[RedCorrection] Val=1.00	0.00 - 1.00	Usefull to fine-tune colors from LED stripe to match colors from TV. These parameters can be also adjusted during runtime with IR remote control.

FRAME_START_LEFT	30	[FRAME_START_LEFT] Val=30	0 - 180	These parameters defines format of video input signal (e.g. 4:3, 16:9 ...). I recommend to use autodetect mode activated by IR remote control (button "16:9").
FRAME_START_RIGHT	330	[FRAME_START_RIGHT] Val=330	180 - 360
FRAME_START_UPPER	30	[FRAME_START_UPPER] Val=30	0 - 156

description of special SCIMO functions


boarder detection (IR command "16:9")
Select a movie or TV channel in any format you want to adapt and let it run. This movie just have to be more bright (no night scene) and contains some motion. Press button 16:9 and wait some time (up to 120 seconds), during this time do not change movie or TV channel and watch out that it is not interrupted from commercial or something like that.
When SCIMO finished detection successfully it will flash all LEDs with green light and work with new configuration.
New settings can be saved to file config file by pressing button "Exit", otherwise they are discarded with next reboot of SCIMO.


Auto Power on/off depending on input signal
As described in feature list SCIMO is able to automatically power off if no input signal is detected (timeout 15 seconds). In same way it wakes up from input signal, but only if it has entered power-down mode before automatically.
So if SCIMO was powered off by remote control or switch, it stays off and won't awake from input signal.

If there was a power brownout than SCIMO automaticly starts working as long video signal is available. If you want to keep SCIMO in standby mode after power brownout you can use parameter "DC_BACK" confgured to "off" (available since firmware V2.0).
