[ PySerial ] 檢查 Serial設備

因為工作需求，需要使用 USB傳輸 Serial data。
之前都是用 Arduino IDE檢查 Port的位置，一直感覺手段不是很漂亮。
最近在 StackOverflow上看到有人分享一段代碼，能夠自動尋找電腦上 Serial的設備。
由於簡單給力，所以我就原封不動的 PO了。

Successfully tested on Windows 8.1 x64, Windows 10 x64, Mac OS X 10.9.x / 10.10.x / 10.11.x and Ubuntu 14.04 / 14.10 / 15.04 / 15.10 with both Python 2 and Python 3.

import sys
import glob
import serial
 
 
def serial_ports():
    """ Lists serial port names
 
        :raises EnvironmentError:
            On unsupported or unknown platforms
        :returns:
            A list of the serial ports available on the system
    """
    if sys.platform.startswith('win'):
        ports = ['COM%s' % (i + 1) for i in range(256)]
    elif sys.platform.startswith('linux') or sys.platform.startswith('cygwin'):
        # this excludes your current terminal "/dev/tty"
        ports = glob.glob('/dev/tty[A-Za-z]*')
    elif sys.platform.startswith('darwin'):
        ports = glob.glob('/dev/tty.*')
    else:
        raise EnvironmentError('Unsupported platform')
 
    result = []
    for port in ports:
        try:
            s = serial.Serial(port)
            s.close()
            result.append(port)
        except (OSError, serial.SerialException):
            pass
    return result
 
 
if __name__ == '__main__':
    print(serial_ports())
