![]() ![]() Second, you need to tell the compiler to use this bridge header in thelinking process. First add a new header file to your project.Īdd the following lines to this bridge header file: To use the ORSSerialPort library in your Swift code you need to link itvia a bridge header. Hooking Objective-C code to your Swift project¶ in case you use XCode prior to 6.3.2you need to disable the NS ASSUME NONNULL BEGIN andNS ASSUME NONNULL END macros and remove the ‘nullable’ property in deORSSerialPort source code. Note, theORSSerialPort library uses the newest API functionality of Apple, likeNS ASSUME NONNULL and nullable. Try to run the project, it should print “Hello World!”. ![]() Xcode should now open with a new folder “Pods” containing theORSSerialPort. Close your earlier created project, and reopen the workspacefile. Import ORSSerialPort¶ĭuring downloading the dependencies CocoaPods creates an Xcode workspaceproject. Start Xcode, and create a new Command Line project for OS X. The last nicefeature of the ORSSerialPort library is that it also handles thethreading related to using the serial port. This library is ORSSerialPort whichprovides a great API for using serial ports in OS X. Wecould write our own wrapper, but luckily, an excellent serial portlibrary exists. The obvious choice is to usean Objective-C or C wrapper as we also will do in this tutorial. The BSD TTY APIs uses complex macros and varargswhich are not supported by Swift directly. Thefirst two are reasonably easy to use from Swift, but the third does notimport quite well. Accessing a serial port in OS X requires the use ofthree API’s: IOKit, common BSD file handling APIs and BSD TTY APIs. This tutorial describes how to implement the simple serial port programin OS X in Swift. The opened serialport file descriptor also conforms to the TTY API for setting serialport specific settings like baudrate. To access the serialport, this handle is just opened as an ordinary file. The serial port handle is available in /dev andhas the prefix cu, which stands for calling-unit. In a Unix environment a serial port is accessed via a file descriptor.This means a terminal program uses the file access API to read and writedata to a serial port. The latter requirementmeans that two processes are necessary running simultaneously. First it shouldinit the serial port, and then it should read data from the serial portand transmit data read from the serial port. Background Information¶Ī simple serial port program has three main functions. It includes a Terminal Emulator, a Protocol Analyzer and a serial port monitor to watch for connections and removals of serial ports. From the developer: Serial Tools is a set of serial port tools for Mac OS X. The size of the latest setup package available for download is 408 KB. The actual developer of this free Mac application is w7ay. Lookup Mac, iPod, iPhone, iPad, Apple Watch, Apple TV and other Apple devices by Apple Order Number, Model Number, EMC Number, Model Identifier, and Serial Number as well as Intel processor number to check its specs and other details. Mac & Apple Devices - 's Ultimate Mac Lookup. The main prerequisite for this tutorialis that you have installed CocoaPods. Weguide you through a reference implementation for your own projectsincluding all practical steps. This tutorial explains how you can program the serial port in Swift. There are a few software apps out there, but I find it much simpler to simply use the terminal application. If you develop on an Apple and find yourself doing any sort of device or embedded development, you will quickly find the need for a serial terminal on Mac. Using screen as a serial terminal on Mac OS X. ![]()
