Frequently Asked Questions
I am running Amblone, and everything is working, but I can't get more than a few loops per second (LPS).
This makes the colours change very slowly and shakey, and is not pleasant at all.
What can I do about this?
If the LPS is really low, for example between 2 to 10 LPS, most of the times this is caused by Windows Aero/desktop composition.
Disabling Aero will most likely greatly increase your LPS.
You can either disable Aero globally
or only for specific programs
The colours on the screen are successfully detected by Amblone whenever I am browsing or using my computer in other ways, but when I am watching a video the colours are not detected at all. Why is this?
The reason why the video colours are not detected is probably because your media player is using hardware acceleration.
This technology causes the image to bypass the conventional way graphics are handled, and takes a 'shortcut' to the GPU.
For this reason, the screen image cannot be accessed by the Amblone software, and hence the colours cannot be extracted.
We are planning to implement a different way to access the screen bitmap in a future Amblone version that would allow it to work with hardware acceleration.
The Amblone software was running before, but it now crashes every time I try to run the program. What can I do about this?
Most times this is caused by a changed setting that causes the program to crash on startup.
You can reset the settings by installing the reset.inf
file in the Amblone install directory.
Right-click this file and select install
. Now try to run Amblone again.
I am building an Amblone system, but the light sources I want to use are different from those in the how-to guide.
For this reason, I might also need different resistors and transistors, but I don't know which ones to get. Can you help me?
Which resistors and transistors you need depends on the current and voltage the light source needs. However, most LED strips and lights will require 12V.
When choosing transistors, you need to look for one that can switch the current that's required by the light source.
If you do not know how much current the light source consumes, you can try contacting the reseller and ask for this specification.
In the datasheet of the transistor you can find how much current it can switch, which needs to be higher than the light source.
When you have found a transistor, you need to choose a resistor. The value of this is not extremely important, and simply has to meet the following demands:
The resistance must be low enough to fully switch the transistor on when the Arduino's PWM is outputting a 1.
The resistance must be high enough to protect the transistor from breaking when the Arduino's PWM is outputting a 1.
For most setups, a resistor of around 2500 Ohm should be sufficient.
