Directly Wired Buttons?

schmulkfuster

I believe there are ways to connect things directly to the GPIO thingy but I'm still quite new to the hardware hacking scene so I can't be much help I'm afraid. I'm sure if you google something like "Raspberry PI Arcade connect buttons to GPIO" you'll find something useful

Exactly what I needed. Thanks.

Hello, I'm trying to wire up credit, pause, exit, tab buttons to my Raspberry Pi with RetroPie but the above link is dead. Can anyone help please? Thanks!

Have mine set up with this, works pukka after a few tweaks in the .cfg

So I've copied over the Adafruit-Retrogame folder and set up the config file. It is set up to run at boot per the /etc/rc.local, but it doesn't appear to be pulling-up the GPIO pins I've assigned (I measured them with a volt-meter). What gives? Can anyone help?

Thanks for all the replies!

I was able to get externally wired buttons to the GPIO inputs to work using the following links:

and

Trick for me was to build the retrogame C file using make... I did have to use "sudo nano retrogame.c", change a line (but didn't change any content), which caused the "m ake" program to recognize that retrogame.c was changed and then make it.

Thank you!

@cybermrc I know I'm a luddite, but I'm afraid I went for the easy option:

The whole lot (1 player anyway) done for you via a USB connection to the Rpi for £22.

Not as clever or cheap, but might be of use to the technically challenged like myself?!
