Raspberry Pi, Processing, and button input... - Raspberry Pi Forums

-

hi folks!

here’s situation: have rpi 1 b+, running processing resource: http://scruss.com/blog/2014/01/07/proce ... arduino-☺/

i’ve gotten processing recognize pi’s serial input this: http://www.raspberrypi-spy.co.uk/2013/1 ... rial-port/

, i’m using (well, trying use) adafruit’s retro gaming controls tutorial connect buttons (i need two, simple buttons) directly pi: https://learn.adafruit.com/retro-gaming ... pi/buttons

problem is, far can tell, processing can’t see button input. so, multi-part question:

1) suggestions setting buttons in way adafruit does?
2) there way can check see if pi registering button press?
or
3) way using arduino handle buttons , pass processing?

sorry links; i’m not trying promote them, thought if people see coming from. thank you! :)

okay, addendum question, easier others:

arcade buttons shown in setup (photo above adafruit retro gaming tutorial) https://learn.adafruit.com/assets/8832 appear have 2 connections, yet ones received sparkfun (thought got them adafruit, wrong, dammit) have three: 2 off side (labeled 2-nc , 3-no) , 1 off of bottom (labeled 1-com).

supposed connect ground, gipo pin, , leave unconnected? :?:

thanks.
