touch sensor buttons for an arcade stick

Post by jaygist »

I play fighting games like Street Fighter or Marvel vs Capcom with a joystick that has a akishop PS360 PCB installed. Here is a link to the PCB:
http://www.BANNED.com/akishop-ps36 ... stick-pcb/

I would like to try to switch out the pushbuttons with the Momentary Capacitive Touch Sensor Breakout. From what it seems like, all I need to do is attach the GRD to a ground on the PCB, the OUT to the input I need, and VDD to either an external power source or the addition 3v VCC provided by the PS360 PCB.

Is that correct?

The data sheet for the akishop board is not explicit about whether the buttons short to GND or V+. You should be able to tell by testing the connection terminals with a meter. If the buttons short to GND, the breakout should work.

I'm doing something similar with the momentary cap touch sensor. For the PCB, im using the Xin-mo dual USB controller board. (http://www.xin-mo.com/?page_id=34)

When i connect OUT from the cap sensor to a button pin on the Xin-mo the button mapping/controller software indicated the arcade button is in a constant "pressed" state. When i touch the cap touch sensor the arcade button state is then off. Basically the reverse of what i need. Either i wired something backwards or i am missing a component in between something??? Cap sensor GND is connected to GND pin on the Xin-Mo, VDD getting power from the usb bus on the PC thats running the arcade emulation. Any thoughts or ideas? Im novice level at EE.

I don't know anything about the Xin-mo board. The momentary capacitive touch sensor sends the output high when you touch it. If the Xin-mo is expecting the inputs to be active low, then what you describe is to be expected. The 5-pad version is active-low, so that might be a better match for your xin-mo board.
