Import winreg as winreg import itertools def enumerateserialports:' Uses the Win32 registry to return an iterator of serial (COM) ports existing on this computer. 'path = 'HARDWAREDEVICEMAPSERIALCOMM' try:key = winreg.OpenKey(winreg.HKEYLOCALMACHINE, path)except WindowsError:raise IterationErrorfor i in itertools.count:try:val = winreg.EnumValue(key, i)yield str(val 1)except EnvironmentError:breakThere are other methods for listing the serial ports, but for the time being I'll stick to this one. A simple GUI for listing the portsFinally, I've coded a simple PyQt based GUI for listing the available ports and allowing the user to try and open them (even if the port appears as available on a computer, it may be in use by another program - so opening it will fail).Here's the code.

NOTE: I will be using a DHT11 temperature sensor to produce data on the Arduino end. Roland spd-sx sounds download. Since this is a tutorial on reading data from the serial port using Python, not Arduino, I recommend visiting a DHT11 tutorial to learn how to print temperature data from the sensor to the serial port (see here, or here). Serial RS232 connections in Python. The PC to Controller connection is a serial RS-232 connection. For the practical parts of the exams we need to write applications which, using the RS-232 communication channels, controls the movements of the robots.

It assumes that the enumerateserialports and fullportname functions were placed in a module called serialutils somewhere on the Python path.Also, note how the simple port names from enumerateserialports are shown in the list widget, and when trying to actually open the port, the program converts them into full names 'under the hood'. This is a common practice in serial-port programming. ' Lists the serial ports available on the (Windows) computer.
