Cheaper than Teensy

Has that been tested on Linux/RetroPi ? I know you told me in a PM that it worked fine in Windows but had some issues in Linux.

I haven't tried it on the raspberry but I tried it on ArchLinux with Fceux emulator on my laptop, but I don't think that would be different.
What I told you by MP was that it did not work with the keyboard method, because the keys were released too shortly after. I might have a solution for this in mind. Actually the gamepad works correctly, and the defines on top allows to change easily the configuration

EDIT2: OOOPS very bad idea. Not working, can't reprogram..

Let me guess, you constantly sent out releases?

Haha not exactly, though same deal, keep sending arrow keys + return and such...
Though as usual, linux was the solution, it allowed me to block the keyboard till I uploaded a new sketch

So here is a simple video showing it working on a Raspberry Pi 2 with Retropie 3.7 installed on it playing Super Mario Bros:

Oh by the way, I did not add the L2/R2 buttons because I don't think any console needs it, we can't emulate Playstation games, do we ?

Well, i can, on my Orange Pi PC.
But to add 2 more buttons will not be that difficult, will it?
Is it keyboard or joystick input now?

[Oxodao]

Actually it is joystick input.
Yeah that won't be difficult, I assumed that everyone would be using a Raspberry Pi Zero.
Just for curiosity, which orangepi are you using ? Does it work wells for emulation ?

EDIT: I added the second R2/L2 button. Code is in the spoiler in the first post

Great, thanks. I will try this tomorrow.

It is called "Orange Pi PC".
I only use it for another project, as it is too big for a GB Case and the other stuff that has to fit in.
But it is much more powerful and as you can read here: http://sudomod.com/forum/viewtopic.php?f=25&t=267
everything works fine. There even is a working RetroPie image now, which gets updated every few days.

Sorry for the dumb question.
What are the advantage of using this solution rather the GPIO pins from RPi3? Isn't cheaper and faster? Also supports multiple press.
(unless we need the GPIO pins for other stuffs).

Thanks.

Could you edit your code to match what is in the BLUE lettering? I have this pretty much done just need to finish some wire traces and will be done.

I've done it, it is in the spoiler on the top of the post.
Though I don't know why Arduino pro micro doesn't have some of the pins you used here... Probably lack of space I'd guess
