IS there any suggested card to do the conversion of a ch fighterstick keeping the original matrix of the stick handle?
Since I have a gameport CH Fighterstick laying around for years, your question make me reminder them, so I decide investigate his matrix.
The plug coming from grip to original PCB has 11 wires - but only 9 are used, what means a 4 x 5 matrix = 20 buttons.
the dark blue and brown wires in the plug has no use.
The wire colors can be see in these PDF:
ftp://ftp.chproducts.com/pub/CHProducts_...ighterstick_PC/What is strange is the fact that are used 8 diodes in HAT PCB's, one diode for each 4 HAT1 (the big china) individual wires (collumns) and one diode for each button (1-4), but no diode in HAT2, HAT3 and HAT4.
HAT1 - common wire = gray
HAT1 UP = white
(diode)HAT1 DOWN = red
(diode)HAT1 RIGHT = orange
(diode)HAT1 LEFT = green
(diode)HAT2 - common wire = yellow
HAT2 UP = white
HAT2 DOWN = red
HAT2 RIGHT = orange
HAT2 LEFT = green
HAT3 - common wire = purple
HAT3 UP = red
HAT3 DOWN = white
HAT3 RIGHT = orange
HAT3 LEFT = green
HAT4 - common wires = pink
HAT3 UP = red
HAT3 DOWN = white
HAT3 RIGHT = orange
HAT3 LEFT = green
Buttons - common wire = black
Button1 = blue
(diode)Button2 = orange
(diode)Button3 = white
(diode)Button4 = green
(diode)All diodes cathode (black list) point toward switchs.
I supposed that matrix collumns are:
Green
Orange
Red
White
Matrix rows
Black
Gray
Pink
Purple
Yellow
These colors are ones from the main board plug for top HAT's PCB,.
From HAT's PCB to button 1, 3, 4 and HAT 4 are used other wire colors but this is not relevant.
If you find I way to plug in some USB card matrix without alteration post here, I dont figure how...
In the time to trace these tiny PCB lines with a multimeter is possible convert two PCB's with the "Redneck force brute method".
