Tessel NES Controller Library
A simple Tessel library for interacting with the original Nintendo controller
The original NES controller has a 7 pin connector but only 5 are actually used. The following image shows what the connections are when looking at the connector.
+----> Power (white) | 5 +---------+ 7 | x x o \ | o o o o | 4 +------------+ 1 | | | | | | | +-> Ground (brown) | | +----> Pulse (red) | +-------> Latch (orange) +----------> Data (yellow)
The colors listed above are the most common but they aren't universal due to the huge number of knockoff controllers made. The best way to be sure is to use the continuity feature on your multimeter to see which wire goes to which hole on the connector after you cut it off. The connector image above shows which hole corresponds to which connection. Once you've identified the wires you can connect them to any port, including GPIO, on the Tessel as follows:
|Controller Connection||Tessel Port Connection|
npm install tessel-nes
var tessel = ;var nesController = ;nesController;
NESController.on('ready', callback(err, controller)) - Emitted when the controller object is first initialized
NESController.on('up', callback()) - Emitted when up button is pressed*
NESController.on('down', callback()) - Emitted when down button is pressed*
NESController.on('left', callback()) - Emitted when left button is pressed*
NESController.on('right', callback()) - Emitted when right button is pressed*
NESController.on('a', callback()) - Emitted when A button is pressed*
NESController.on('b', callback()) - Emitted when B button is pressed*
NESController.on('select', callback()) - Emitted when select button is pressed*
NESController.on('start', callback()) - Emitted when start button is pressed*
*Button events will only fire after startListening() has been called
NESController.query(callback(err, buttonStates)) - Query the controller button states
NESController.startListening() - Controller will start polling for button presses and fire events when detected
NESController.stopListening() - Stop polling for button events.
- Button Events. Demonstrates how to listen for button events.
