I-PAC to X-BOX project.. help!
AndyWarne:
I need some help here!
I got as far as buying my very first console ever, an X-BOX.
Into the workshop, off with the top, cut open the video plug (who needs warranties anyway!) wired up to my trusty NEC Multisync II.
Wasted about 2 hours trying to work out why the Red and Blue signals were missing and the picture was all green. Then dawned on me that the picture is supposed to be all green on boot up dammit!
mattfl:
you know they make a little converter so you don't cut open the video plug to hook it to a pc monitor right?

I'm not having a good day today, hit xmit before finishing the post!
Anyway what I was going to ask was,..anyone know anything about these?
The controller has normal buttons and a hat switch which of course are going to be pretty easy to implement in the I-PAC chip.
The mushroom things are analog so these will need to have an emulation ie "pressed fully over" when the joystick switch is pressed.
First question: Is it necessary to have a manual switch over between the emulation of the hat and the mushroom? Or can I just actuate both in the assumption that the game will not mind?
If I do need to switch over from hat to analog, I wonder what is the best way to do this, and how often the switch over needs to be made. Is once per boot-up OK or would it be on-the-fly?
Do any games use the hat and the mushroom together for different functions?
I'll probably have other questions later. If anyone wants to assist and beta-test drop me an email.
Thanks
Andy
AndyWarne:
I don't think a converter would have worked directly. The X-BOX seems to only be capable of sending 15Khz RGB with composite sync which is at a 0.3 v level. (apart from composite PAL or NTSC video of course).
I got around this by wiring the composite sync to the Green signal and the NEC detects this as "sync on green".

There are quite a few games that use both the digital pad and the analog sticks - Splinter cell comes to mind first...many games use the sticks to move and digital pad to select stuff or perform inventory funcitions.
