import serial failure


J

J W Burton

I have installed both Python 2.7 AND Python 3.3 and the corresponding pyserial files from

ihttps://pypi.python.org/packages/any/p/pyserial/pyserial-2.7.win32.exe#md5=21555387937eeb79126cde25abee4b35n my

for 2.7

When I look in my Python27/Lib/site-packages/serial folder I see
package files

but when I run a program using import serial, I get an error
Traceback (most recent call last):
File "C:\Users\Jahree\serial.py", line 2, in <module>
import serial
File "C:\Users\Jahree\serial.py", line 5, in <module>
ser = serial.Serial(
AttributeError: 'module' object has no attribute 'Serial'

I'm guessing there is a path not set correctly - I'M STUCK

Please help.

Thanks

ps: the following is serial.py file I'm using for testing.

import time
import serial

# configure the serial connections (the parameters differs on the device you are connecting to)
ser = serial.Serial(
port='/dev/ttyUSB1',
baudrate=19200,
parity=serial.PARITY_ODD,
stopbits=serial.STOPBITS_TWO,
bytesize=serial.SEVENBITS
)

ser.open()
ser.isOpen()

print('Enter your commands below.\r\nInsert "exit" to leave the application.')

input=1
while 1 :
# get keyboard input
input = raw_input(">> ")
input = input(">> ")
if input == 'exit':
ser.close()
exit()
else:
# send the character to the device
# (note that I happend a \r\n carriage return and line feed to the characters - this is requested by my device)
ser.write(input + '\r\n')
out = ''
# let's wait one second before reading output (let's give device time to answer)
time.sleep(2)
while ser.inWaiting() > 0:
out += ser.read(4)

if out != '':
print(">>" ,out)

Your file is named serial.py, so "import serial" in that file will try
to import itself. You can see this in the traceback you posted,
everything is coming from "C:\Users\Jahree\serial.py". Rename your
serial.py and things should work as expected.

Hope this helps,

Your choice of filename is unfortunate ;)
import time
import serial

The file is importing itself here. Rename your

C:\Users\Jahree\serial.py

to something unique, say

C:\Users\Jahree\myserial.py

delete

C:\Users\Jahree\serial.pyc

and everything should be OK.
