## ORSSerialPort
ORSSerialPort is a powerful library for working with serial ports on macOS. It provides a simple and easy-to-use API for opening, closing, reading from, and writing to serial ports.
### Installation
To install ORSSerialPort in your project, you can use CocoaPods. Simply add the following line to your `Podfile`:
“`ruby
pod ‘ORSSerialPort’
“`
### Usage
#### Opening a Serial Port
To open a serial port, you need to create an instance of `ORSSerialPort` and set the desired port name and settings. Here’s an example that opens a serial port with a baud rate of 9600:
“`swift
let serialPort = ORSSerialPort(path: “/dev/tty.usbserial”)
serialPort.baudRate = .baud9600
serialPort.open()
“`
#### Reading Data from a Serial Port
Once a serial port is open, you can start reading data from it. `ORSSerialPortDelegate` provides a method called `serialPort(_:didReceive:)` that gets called whenever new data has been received. Implement this method to handle the received data. Here’s an example that prints the received data:
“`swift
func serialPort(_ serialPort: ORSSerialPort, didReceive data: Data) {
guard let string = String(data: data, encoding: .utf8) else { return }
print(“Received data: \(string)”)
}
“`
#### Writing Data to a Serial Port
To send data through a serial port, use the `writeData(_:)` method of `ORSSerialPort`. Here’s an example that sends a string:
“`swift
let data = “Hello, Serial Port!”.data(using: .utf8)!
serialPort.writeData(data)
“`
#### Closing a Serial Port
To close a serial port, call the `close()` method of `ORSSerialPort`. Here’s an example:
“`swift
serialPort.close()
“`
### Additional Functionality
#### Available Serial Ports
To get a list of available serial ports, use the `availableSerialPorts()` class method of `ORSSerialPortManager`. Here’s an example that prints the available serial ports:
“`swift
let availablePorts = ORSSerialPortManager.shared().availablePorts
for port in availablePorts {
print(“Available port: \(port.path)”)
}
“`
#### Observing Serial Port Additions and Removals
To receive notifications when serial ports are added or removed, use the `serialPortsWereConnected(_:)` and `serialPortsWereDisconnected(_:)` methods of `ORSSerialPortManagerDelegate`. Here’s an example:
“`swift
extension YourClass: ORSSerialPortManagerDelegate {
func serialPortsWereConnected(_ newPorts: [ORSSerialPort]) {
for port in newPorts {
print(“Port connected: \(port.path)”)
}
}
func serialPortsWereDisconnected(_ removedPorts: [ORSSerialPort]) {
for port in removedPorts {
print(“Port disconnected: \(port.path)”)
}
}
}
“`
