ofxArduinoDjShield

Openframeworks addon C++

Addon to use easily the DJ Shield for Arduino by Nootropic Design

<https://nootropicdesign.com/djshield/>

Specification of the DJ Shield for Arduino :

• 5 tactile buttons, connected to digital pins 2-6
• 3 10K linear potentiometers connected to analog pins 0,1,2. (shaft is 1/4")
• 2 LEDs (one red, one blue) connected to analog pins 4 and 5 (analog pins can also be used as digital pins)
• 3 ABS plastic or aluminium knobs for the potentiometers.
• Compatible with the Arduino Uno, Duemilanove, Mega or Leonardo

Webpage for the addon : <http://www.fluate.net/code/ofxArduinoDjShield>

USAGE:

• Get an Arduino Uno, Duemilanove, Mega or Leonardo <http://arduino.cc/en/Main/arduinoBoardUno>

• Upload StandardFirmata on the arduino :

Open Arduino app (preferably Arduino 1.0) and navigate to File -> Examples -> Firmata and open StandardFirmata. Compile and upload StandardFirmata for your board, then close the Arduino application and run the application.

• Get a DJ Shield for Arduino : <https://nootropicdesign.com/djshield/>

• Add to your code :

in ofApp.h add :

include "ofxArduinoDjShield.h"

and after "public:" : ofxArduinoDjShield DjShield; bool ArduinoUSB; // if Arduino connected to USB port string deviceInit;

in ofApp.c add :

• in setup() { }

vector <ofSerialDeviceInfo> devices = (ofSerial()).getDeviceList();

for(auto & device : devices){ if(device.getDeviceID() == 0){ deviceInit = device.getDeviceName(); } }

// Here the list of 4 USB Port of the computer, change them in case.. // replace the string below with the serial port for your Arduino board // you can get this from the Arduino application or via command line // for OSX, in your terminal type "ls /dev/tty.*" to get a list of serial devices

string ArduinoPort01 = "tty.usbmodem1411"; string ArduinoPort02 = "tty.usbmodem1d11421"; string ArduinoPort03 = "tty.usbmodem1421"; string ArduinoPort04 = "tty.usbmodem1431";

if((deviceInit == ArduinoPort01) || (deviceInit == ArduinoPort02) || (deviceInit == ArduinoPort03) || (deviceInit == ArduinoPort04)){ ArduinoUSB = true; } else{ ArduinoUSB = false; }

if(ArduinoUSB){ DjShield.setup("/dev/" + deviceInit); } --------------------------------------

• in update() {}

if(ArduinoUSB){ DjShield.udpate(); // then use :

bool DjShield.bSetupArduino // if arduino ready // Potentiometers A0-A2 float DjShield.PotA0(); // native, from 0 to 1 float DjShield.PotA1(TRUE, 0,255); // rescale from 0 to 255 float DjShield.PotA2(TRUE, 3, 10); // rescale from 3 to 10

// Buttons D2-D6 bool DjShield.ButtonD2(); bool DjShield.ButtonD3(); bool DjShield.ButtonD4(); bool DjShield.ButtonD5(0.5); // 0.5 s delay before next hit bool DjShield.ButtonD6();

// LED A4-A5 DjShield.LedA4(true); DjShield.LedA4(false); DjShield.LedA5(true); DjShield.LedA5(false); }
