I-PAC and LED's??

(1/2) > >>

lettuce:
Does anybody know which pins on the I-PAC are used for what LED lights, Caps/Num/Scroll lock??

I have got some push buttons from Ozstick, the PB05 Square Illuminated Buttons with 12V Filament Globe illumination, can i connect the bulb side of these buttons to the correct pins on the I-PAC? Does the I-PAC actually Power the 12v bulbs for these buttons, and if so are they on all the time, and then just flash for certain games depending on which pins you connected them to on the I-PAC??

RandyT:

Don't do it!  You'll likely cook those inputs if you try.

Search the forums for circuits people have used to make things like this work.  It can be done, just not as simply as you had probably hoped.

What Randy said... you need to build this circuit, except using a 12V source and appropriate resistors, etc:

They used to be for sale in 5V form from gamecab but they have been out of stock forever:

Here's how you wire it:

The ipac doesn't have the juice to drive even superbright LEDs, much less incandescent bulbs. 
Just a side note, if you are going to be using MAME to flash your player start buttons, you'll need a build prior to v0.104 because they broke the LED flashing code around then.

I tried using LED flashing in 1.07 and all the 3 lights lit up and blink when there are credits available (Omega Race for example).

I have never been able to get mine to work. :banghead:
I suppose I'll have to take a closer look at it.
