My hardware/Software computer control system - Wish list/feedback - Easy power off
This is not a question post, but a feedback one. I'm in the middle of my project "R/T" in which I'm building a car audio system. I've decided to go ahead and install a computer as well with an LCD display. To get down to the point of things, from what I see there is nothing out there to control ATX shutdowns. I'm going to change that.
First off, What I will be working on is a hardware/software based system that will control the computer from an input controller. The specs are as follows
Controls: 8 control functions total to start
c1: Power Off - Must have ATX MB/PS in order for the computer to power down
WinAmp Controls - possible in time -
Other possible controls - open for debate -
c7: Quick launch - Per say to run AutoTap with a push of a button -
c8: Unknown - Off the top of my head I can't think of any -
Hardware - Game port interface
As far as I know, all sound cards have a game port, and all motherboards with built in sound also have this port, allowing it to be used for any application. If I am wrong on this feel free to correct me, however I think that 99.9% of you will have an open game port.
Software - The heart of operations, will run on Win95/98/ME/NT -
The software I will be designing for this will begin as a hard coded system, however later I may expand to allow settings of what command function does what.
As I said, to start I will be using an 8 command base system. For now I'd like you to think about what possible commands could be placed in it. Or possible commands that could be added to an extended version. At this moment I'm not going to think through how many commands I can build in, but from what I'm guessing I can get 20 - 30 commands that can be read from the hardware by the program, using a double action, single command system.
Now as a reminder, this is a way to control the computer via the car (relays on events, door open, etc etc) or via push buttons. This is NOT a way for the computer to control car functions (rolling down windows, opening doors, etc). It is a ONE WAY system.
For those of you wishing to just have a software control, I will be building a special one that just makes use of a normal 2 button, 4 axis game controller (IE game pad). This will save time on having to wire a more complex system to handle multi functions. Thus the game controller could do the following;
Up Arrow: Play
Down Arrow: Stop
Right Arrow: Next
Left Arrow: Previous
Button One: Pause
Button Two: Shutdown Computer
Keep in mind I am only in the thinking stages of this software/hardware system. As I have yet to get the amp racks done in my car, the computer is not on my list at this moment. Also, I will have to research how to control WinAmp via an outside program in order to get the music functions to work.
At any rate, Input is greatly welcome. I fully intend to release both the compiled program as well as schematics for the hardware control system/interface.
P.S. My first time posting to the forums. Been alot of helpful people here, glad to see all this knowledge out in the open.. ;)
