iOS应用Modbus使用Swift读/写

Question

I have not programmed in C before and now learn Swift for iOS. I'm creating an iOS app that needs to talk to devices via Modbus. I'm trying to use ObjectiveLibModbus https://github.com/iUtvikler/ObjectiveLibModbus but I don't know where to start.

How to import this library in my Swift app and how using it?

Or does anyone have another library of code for use Modbus protocol in Swift app?

Answer 1

For Swift new library available for modbus: new Swift fork ktsakaguchi/SwiftLibModbus

Now make a new instance of SwiftLibModbus and connect:

let swiftLibModbus = SwiftLibModbus(ipAddress: "192.168.2.10", port: 502, device: 1)
swiftLibModbus.connect(
    { () -> Void in
        //connected and ready to do modbus calls
    },
    failure: { (error: NSError) -> Void in
        //Handle error
        print("error")
})

Make a modbus call:

swiftLibModbus.readBitsFrom(1000, count: 5,
    success: { (array: [AnyObject]) -> Void in
        //Do something with the returned data (NSArray of NSNumber)..
        print("success: \(array)")
    },
    failure:  { (error: NSError) -> Void in
        //Handle error
        print("error")
})

Disconnect when you are finished with you're modbus calls:

swiftLibModbus.disconnect()
