If you already installed the library and connected everything, just burn the code bellow in the Arduino and you have finished. More information can be found in this useful document.

Repeat the step four for the next 14 bits(16 bits are read, but some are always high).Īs said before, pretty easy to read.

Toggle the clock light form low to high, read the bit, toggle the clock line to low again.

The first bit(button B state) will be already in the data line, read it.

This instructs the controller to lock the state of the buttons for reading. In the connector of the controller there are two lines for power (5v and ground), and three other lines, one for cock, one for data, and the other is the latch line. The SNES controller protocol is pretty simple. I choose to use the two controllers code, because I only had two SNES controllers anyway.

Then you can code the board to receive the button states from the controllers and send them to the PC as a USB HID controller. With this library, you can make the Arduino appear in the computer as up to 3 controllers.

Just download it and extract in the libraries folder of the Arduino IDE files. The library I found works great, it was coded by Matthew Heironimus, and can be found here.

If you don’t have the version 1.6.6, please update so we can continue. Ops, I assume that you have the last version of Arduino software, because the library does not work with version 1.6.5 or below. In addition, I wanted to complete the project in one afternoon. I still don’t know much about the USB protocol and its way of communication. A reading in the code can clear this better. Note: Every line is shared between the controllers except the data line, this means that latch, clock, 5v and GNd are connected in the controllers connected, the data lines must be separated, I used the pin D6 for the data line of the second controller. I connected as follows, but you can change in the code if you want. The SNES controller connector pinout is : In my defense, I used the worst soldering iron ever. You can see the details below: I used two male pin from headers to make the connector. For this I used some veroboard and male headers basically.Please, remember that only the Arduino micro and Leonardo can be used for this. I had to connect the controllers to the Arduino.

The models Micro and Leonardo have a USB port in the ATmega used (32u4), and only one chip is used for USB communication and general coding. Usually the user may not even realize that the board has two processors. Note: The other Arduino models generally use another ATmega to handle the USB protocol, while the main chip is used for code. The Arduino Leonardo is probably suitable for this too, as it also has a native USB port. The thing about the Arduino Micro, is that like the Arduino Leonardo, it has native USB, being able to act like a keyboard, a mouse, a joystick, or whatever. However, I had a Arduino Micro and some veroboard. I wanted to play Super Mario, but I did not have this adapter anymore. I found the USB implementation to hard to understand, so I just followed the instructions. Some time ago, I built a adapter for connecting SNES controllers to PC from Raphaël Assénat’s site using a ATmega 8 with the VUSB library.

I don’t think I play bad using the keyboard, but I prefer using controllers, even better if the controllers are the ones of the console emulated. I have played in emulators since always, a lot of them, including the SNES. I had the Megadrive, but played some lot in Super Nintendo too. Super Nintendo, together with the Sega Megadrive (or Genesis) are the representative consoles of the 16-bit era.
