I am building a “mini-arcade” built around an iCade and a raspberry pi. I want to add a “touch sensor” button, which is sold by sparkfun.com and is based on the AT42QT1010. I am interfacing the joystick/buttons using a “zero delay” USB encoder I bought off eBay.
Question is, can the digital output signal be used by the USB encoder, or do I need to connect the output directly to the GPIO? I read somewhere that pin 5 already has a pull up resistor on it. It seems every pi tutorial on buttons involves lighting an LED; all I want to do is read the button push.
appreciate any help!
