Btw: You can always use GPIO inputs to call commands

If you're not like me and prefer USB connections. ;) (because, I don't know, lazyness?)

cyperghost

@Clyde Well ... I think it's not lazyness. I think with this Breadboard unit on Amazon.de there is no space for any excuse ;)
So you develop your scripts and connections on this board and just take them over to your RetroPie ;)

Clyde

@cyperghost If I compare this to a ready-to-use usb device like a keyboard or game controller, I think I can still plead lazyness with a clear concience. ;)

@Clyde Now we are getting closer why I entered this thread ;)

So does triggerhappy work out of the box with joypads? If yes then this would be a real cool deal ;)

Maybe I will post a thread of annother solution that's only script based ;) Stay tuned ;)

If it's reading the events correctly from /dev/input/eventX, I see why not. You can verify like @clyde did via thd --dump /dev/input/*. Looking at the supported event types (thd --listevents), I think it should work.

@mitu Yes I'm reading the github content now. Sounds feasible for me to get this work with js0 as input source. Even one issue on github explainded that there were inputs of buttons detectable.

But I'm also in annother doc for retropie: Take and Scrape Your Own Screenshots. There it is explained

How to setup the screenshot function with button
How to retrieve Screenshot name from ROM name
How to store them per system

The only minus point of the ~~raspi2png~~ internal retroarch solution is... this will work (of course) only in lr- core emulatores ;) Or did I misunderstood the whole thread?

hermit

Rapi2png , I think it works with any emulator.
I used it with uae4arm which is not Libretro

mitu

@cyperghost It works with any emulator, since it screenshots the framebuffer. What you should - actually - do is make it work on the 'Droid (i.e. find a raspi2png substitute).

Yes... I ment that the retroarch internal solution will only work on lr-cores

@hermit @mitu
Corrected previous posting

But I think the internal screenshot modul of retroarch should not be underestimated, too ;)

mitu

@cyperghost Well, if you're using RA, it gets much easier - like in the wiki page you posted. It's enough to bind a button (for instance B, which is mapped to Reset Content) to take a screenshot via the hotkey.

cyperghost

@mitu so the thread should contain all application purposes.

about the odroid.

I'm not a chip developer
the device and it's esp. the graphic drivers are barly maintained
I'm the (proud??) owner of such a device but I prefer the Pie

Maybe the device will get better support if more devs will take buisness on development ... but the XU4 is far away from being called a "newcomer" it's in meantime a 4 year old boy ;)
But let us talk in other threads about this SBC ;)

What I meant - since you have one - maybe you can find an equivalent program to raspi2png for the Droid and be able to test it (not create one from scratch). Something like fbgrab or fbdump maybe.
