View Full Version : NES or SNES controller hookup?

01-23-2006, 04:35 AM
I am·wanting to control my basic stamp 2 with a NES or SNES controller. These controllers seem to have plenty of buttons for my purpose. I just need some help translating the documentation I found into code for my Basic Stamp 2.I am a beginner at this having only completed·maybe half of·the exercises that came with the Boe-Bot kit. For this reason I don't really understand the timming issues that might appear. My intended use is similar to a controller for a·RC car and will require both the D-pad and both buttons. I am currently just trying to see how hard this project might be and·do not have one of these controllers available to test. The documentation is at http://pinouts.ru/data/snescontroller_pinout.shtml. Any help on this would be appreciated.

The link you attached describes something quite simple to impliment.

First before you start with the SNES controller, buy a 74HC595, and a 74HC597, they are very cheap chips, and you can learn the commands of "shiftin" and "shiftout".

Read about shift registers here:

www.parallax.com/dl/docs/books/sw/exp/sw24a.pdf (http://www.parallax.com/dl/docs/books/sw/exp/sw24a.pdf)

These are both(and more) located in the online parallax stampworks library. I suggest you look the collection over.

Meh. Nothing here, move along.

For SHIFTIN experiments (that will ultimately help you with the NES controller), you may want to try the 74HC165 -- it's the compliment of the 74HC595.
