pyserial port scan

if you are using pyserial module to read the communication from your device on UART , you will have to know which port the is your system connected to.

the following is a simple code to scan through all the COM ports and find out which com port is in opened. at the end of the program , you will see the serial uart that is in use being printed

import pyserial
for i in range(256):
try:
s = serial.Serial(i)
available.append( (i, s.portstr))
port = i
s.close()
except serial.SerialException:
pass

ser = serial.Serial(port, 115200,timeout=1)
print ser.portstr


happy scripting!

pyserial

pyserial module is really useful . i have been using it for perfroming uart related communication.
there a lot of sites which provides this pyserial downloads.
import serial
ser = serial.Serial(0) # open serial port
print ser.portstr # prints the used port
ser.write("hello") # write a string
ser.close()
you can use the above code as a test program for performing a pyserial communication from windows.
