Question

Just wondering, is there any "API" for sending signals through a USB cable to a device using Apple's cocoa programming language, so I could incorporate it with an app?

is it much more complicated than a couple of commands, or do i need a library?

I have no experience with external device communication so any help is welcomed!

Was it helpful?

Solution

You will need to read up on IOKit to do USB on OS X. There are some cross-platform libraries like libusb that can come in handy, too. What kind of device do you want to use?
