Controlling an Arduino with Cocoa (Mac OS X) or C# (Windows)

Step 2 Coding the app

Hopefully this makes sense. If you need help please ask any questions you have.
Note: If you don't want to code the app, or you don't have xcode, you can find the app in the source code download under: 'Build -> Debug'

Create the project:
 1) Open Xcode
 2) Press 'Command + shift + n' This will open the new project dialog
 3) Select 'Cocoa Application' under "Mac OS X -> Applications" Press Next
 4) Call the app what you want. I'm calling mine "Arduino Controller"

Add your class:
 5) Once the project is created, Press 'Command + n'
 6) Select the Objective-C Class option from the Classes option under the Mac OS X section
 7) Call it MainController. Then press finish

Add the code:
 8) Open MainController.h
 9) After the '}' & before the '@end' add the code:

-(IBAction)ledOn:(id)sender;

-(IBAction)ledOff:(id)sender;
 

 10) Open MainController.m
 11) After the code ''@implementation MainController" & before the '@end' add the code:

 

-(IBAction)ledOn:(id)sender{

popen("echo i > /dev/tty.usbserial-A6006hmi", "r");

}

 

-(IBAction)ledOff:(id)sender{

popen("echo o > /dev/tty.usbserial-A6006hmi", "r");

}

Finishing The Coding:

12) Press 'Command + b' & press save all
13) Double click on MainWindow.xib. It is located under Resources

14) Interface Builder will open
