Is it possible to use swift and of together?

iOS
#1

And i want to use iPhone control arduino via wifi.
which is more easy to use?

#2

Yes

there is a bit of a process involved but its doable. You really shouldn’t need swift at all to do what you are asking though

#3

You could use Swift, however it would be a great amount of work as Swift doesn’t have any interoperability with C++ (oF) and you would need to write a C or Objective-C++ layer to isolate the two. If your goal is to communicate with an Arduino via Wi-Fi, I’d imagine there might be easier ways than Swift and oF.

These discussions might be worth a quick read:

Thank you.
Because I have not wrote code for iOS before.
so i do not know how to just use OF to write a app for iOS.
But there are a lots of books for me to learn with swift.
And another reason is there are some bugs in the example for Of for iOS…

#5

I am wondering if it makes sense to modify firmata in a way that i can send it via ethernet, wifi or bluetooth?
Any disadvantages?

#6

In this case, I’d say use Swift or oF, as using both would be more work and would mix at least 3 languages together.

What is your goal, to communicate with an Arduino from an iOS device? How is the Arduino connected, BLE, Wi-Fi directly, ethernet to shared Wi-Fi?

#8

that’s great if i can do so

#9

wifi

#10

There is a firmata variant already, check out the github and specifically configurable firmata. I think there is even an example of how to use the ethernet shield or ethernet board

#11

Thanks a lot. I will give it a try.

#12

I read it.But it seems for arduino.
But what to do with iPhone?

#13

This is not so hard, if your arduino needs to wireless as well you can use a wifly to get wifi on your arduino and this library lets you use OSC

And here is a sheild

Just by modifying the OSC example for OF you can get the communication going pretty fast.

However you can choose a lighter library and just use this library

Onyx Ashanti has a great tutorial (there was one error I found PM me if you go down this route and I can dig out the code) for setting up a wifly with arduino

Of course you can also do these things with an ethernet shield or arduino ethernet and the process is the same. There are a few implementations of OSC for arduino but here is one that works well and has clear instructions

OSC makes a simple structure for messaging, but you can also use plain UDP, there are examples for OF in the download and also with the arduino ethernet library
