This (private created (Windows-Program (Visual-Studio C# Project) deals with decoding/analyzing Audio-Output or CPU-Temperature, calculate RGB-Values from them and sending them via Serial to any device (See: Ardunio-RGBDriver)
Attention: A very big part of this code is copied from: www.codeproject.com
I only extended this code by my needs and do not claim that it's mine. I just wanted to contribute my code to other with similar ideas!
As I mentioned this is a Windows-Application and as far as I know the Bass-library supports Vista but not below.
The binary is located in \Audio_CPU_RGB\bin\Release\ and is called Audio-CPU-RGB.exe
It is rather hard to get the CPU-Temperature from default Windows libraries. I tried one which only worked on my Laptop but not on my desktop PC. So i downloaded OpenHardwareMonitorLib and now it seems to work.
How do you divide a temperature by 3 color values? Well, i thought, blue is cold, green is medium and red is hot. Simply as that i said blue is 30 °C, green is 50 °C and red is 70 °C.
So i wrote down a small Diagram
The mathematical equations for these are:
As I told the main part of getting the audio was not my work, but I continued it. But how do you convert a 16-row-spectrum to RGB-colors? Well fortunately this value-range is also from 0 to 255 like the colors. So I divided 16 rows to 3 parts for red, green and blue, calculated the average of each color.
- Visual Studio 2015
- OpenHardwareMonitorLib (0.8.0.0): ohm
- bass.dll (2.4.15.0), Bass.Net.dll (2.4.14.1), basswasapi.dll (2.4.3.1): bass
- LogitechLedEnginesWrapper.dll
Attention: When compiling to a new Solution Configuration ("Debug", "Relase", etc.) be aware that you copy the 4 dlls ("bass.dll", "Bass.Net.dll", "basswasapi.dll" and "OpenHardwareMonitorLib.dll" into the folders \Audio_CPU_RGB\bin\<SolutionName> and \Audio_CPU_RGB\obj\<SolutionName>)!
An example for how both programs interact can be found on Youtube
