No I'm not talking about controlling an Arduino with a chocolate bar or cocoa powder. I'm talking about the programming language, Objective-C. So what is cocoa? Cocoa is a set of frameworks written in the programming language of Objective-C for Mac OS X. No there isn't a test at the steps so you don't have to worry about remembering all of this. Just know that when I talk about cocoa I'm not trying to make you hungry.
Now I understand some people are probably wondering why you would want to use Cocoa instead of Processing, the reason I have is: if you use Cocoa over Processing you can have a full Computer Application(e.g. Safari, Mail, iCal) that can have a physical output. (e.g. Lights, motors, servos)
So Have Fun, Work hard, & Play nice! Please ask any questions you have!
Notes:
- This will only work for Mac OS X & Windows
- The source code is attached below.
- If you don't want to code the app, or you don't have xcode, you can find the app for OS X in the source below under: 'Build -> Debug'
- The instructions for Windows are in step 7

Trouble loading code to Arduino board from Mac OSX Mavericks. Ask Question. I did this by overflowing the memory on my board which wrote bytes into the whole of the program space including the boot loader. For me the solution was installing this CH341 Serial Driver for Mac. Share| improve this answer. Answered Jul 18 '15 at 11:28. The open-source Arduino environment makes it easy to write code and upload it to the i/o board. It runs on Windows, Mac OS X, and Linux. The environment is written in Java and based on Processing, avr-gcc, and other open source software.
I already made a similar question. This is a simple program in c++ wich send an angle to arduino through a serial port, and arduino apply that angle to a Servo motor.
What Program For Mac Wirtes Arduino Codes
This is c++ code
and this is arduino's:
the problem is that it stops at arduino.open(...) , and i don't know why, it doesn't even write 'check-1', and i'm also sure that is the port selected in the arduino app in tools>serial port.
It could be also usefull to know that if i write arduino.open('/dev/tty.usbmodem3a21',iOS::binary) or i write the wrong serial port name it writes 'check-1', 'check-2' and 'ERROR!!', so the error works.

The arduino shows up as a serial device. You should look at using the open() and close() function. I've done this on Linux but I'm pretty sure this works similarly on Mac. This is an example snippet of code. The first snippet opens and sets up the file descriptor.
This just closes it:
To read from the actual file descriptor:
