Nopileus Posted June 1, 2013 Posted June 1, 2013 I'm in the process of putting a new grip in my FFB2 but have run into a problem. Extracting the PCB that houses the sticks buttons i have found that they are wired up in an unconventional way involving four little three-legged ICs and only using 6 wires for 8 buttons. I am searching for a way to wire this up without using sixteen wires since room inside the sticks shaft is limited and i want to understand how this works. I have uploaded Pictures of it here http://imgur.com/a/B8Q0p and also tried marking the traces here http://imgur.com/a/BtfYx As you can see the brown and red wires lead to two of the ICs each, these split up lines each make contact with one switch. Every one of the other colours is then connected to the other legs of two different switches. My knowledge of electronics is somewhat limited, so i have no idea what i am looked at here.
Nopileus Posted June 2, 2013 Author Posted June 2, 2013 After a late night soldering session and plenty of wires it turned out good. I mixed up left/right on the hat but can't be bothered to change that. The grip is from a Thrustmaster X-Fighter. To mount the grip i just wrapped electrical tape around the shaft and screwed on the grip around it, this results in a perfectly solid connection. This is also without any modifications to the FFB2s plastic parts so i can reverse it if need be.
