We open the serial port at COM1 at 19200 baud rate, with timeout 1 second. Then we check make sure the port is indeed open with the ‘isOpen()’ method. The code then enters a ‘while’ loop and wait for user’s input. Note that the input method for Python 3 is different than in Python 2. Do specify a timeout when opening the serial port otherwise it. Do also have a look at the example files in the examples directory. Python-m serial.tools.list. Code can be downloaded from the following link:- http://embeddedlaboratory.blogspot.in/2016/06/serial. Do specify a timeout when opening the serial port otherwise it. Do also have a look at the example files in the examples directory. Python-m serial.tools.list.

IsOpen () False Implementing the Simulator Module So, all we have to do is create a module called fakeSerial.py that will contain • a class called Serial() that can be initialized with various amount of arguments • a member variable of this class should be called name and return the name of a port. • a method called write( ) which receives a string and passes it to the fake Arduino • a method called read() which will read some number of bytes from the Arduino • a method called close() that closes the port and make all further operations with the Arduino impossible. • a method called isOpen() which will return True or False depending on whether the port to the fake Arduino is opened or closed. • a method called readline() that will return characters until a n is found.

Below is our first attempt at building this module. # fakeSerial.py # D. Thiebaut # A very crude simulator for PySerial assuming it # is emulating an Arduino. # a Serial class emulator class Serial: ## init(): the constructor. Many of the arguments have default values # and can be skipped when calling the constructor. Def __init__ ( self, port = 'COM1', baudrate = 19200, timeout = 1, bytesize = 8, parity = 'N', stopbits = 1, xonxoff = 0, rtscts = 0 ): self. Name = port self.

Port = port self. Timeout = timeout self. Parity = parity self.

Baudrate = baudrate self. Bytesize = bytesize self. Stopbits = stopbits self. Xonxoff = xonxoff self.

Rtscts = rtscts self. _isOpen = True self. _receivedData = ' self. _data = 'It was the best of times. N It was the worst of times. N ' ## isOpen() # returns True if the port to the Arduino is open. False otherwise def isOpen ( self ): return self.

_isOpen ## open() # opens the port def open ( self ): self. _isOpen = True ## close() # closes the port def close ( self ): self. _isOpen = False ## write() # writes a string of characters to the Arduino def write ( self, string ): print ( 'Arduino got: ' + string + '' ) self. _receivedData += string ## read() # reads n characters from the fake Arduino. Actually n characters # are read from the string _data and returned to the caller. Def read ( self, n = 1 ): s = self. _data [ 0: n ] self.

_data = self. _data [ n:] #print( 'read: now self._data = ', self._data ) return s ## readline() # reads characters from the fake Arduino until a n is found. Def readline ( self ): returnIndex = self. Index ( ' n ' ) if returnIndex!= - 1: s = self. _data [ 0: returnIndex + 1 ] self.
