Import serial module

Hello Aneesh,

Could you please attach sample code example for investigation? Do you use the same interpreter in your project (and run configuration) and in terminal?

import serial
import time
from Logger import *
from Timeout import *

LOG_WR = 'WR'
LOG_RD = 'RD'
STIMER = 1
"""
Singleton class implementation of Serial Communication.
Limited to only one connection
"""

class Serial_Comm:

def __init__(self, port, baud):
self.baud_rate = baud
self.port = port
self.log_handle = DebugLogger()

def write(self, in_msg=''):
"""
Perform a write operation on UART port
:return: <None>
"""
self.log_handle.log(self.log_handle.INFO, LOG_WR, "Opening Serial Port")
# open serial port
serial_uart_port = serial.Serial(self.port, self.baud_rate)
if (serial_uart_port.isOpen() == False):
serial_uart_port.open()
self.log_handle.log(self.log_handle.INFO, LOG_WR, "Port Opened for Writing ......")
# write a string
serial_uart_port.write(in_msg)
self.log_handle.log(self.log_handle.INFO, LOG_WR, "Writing Successfully Completed")
self.log_handle.log(self.log_handle.INFO, LOG_WR, "Closing Serial Port")
# Close port
serial_uart_port.close()

def read(self):
"""
Perform a read operation on UART port
:return: <rcv>
"""
rcv = ''

self.log_handle.log(self.log_handle.INFO, LOG_RD, "Opening Serial Port")
# open serial port
serial_uart_port = serial.Serial(self.port, self.baud_rate)
if (serial_uart_port.isOpen() == False):
serial_uart_port.open()
serial_uart_port.setTimeout(1)
while (STIMER ==1):
self.log_handle.log(self.log_handle.INFO, LOG_RD, "Port Opened for Reading ......")
# Read data
ch = serial_uart_port.read()
rcv += ch
if not ch:
self.log_handle.log(self.log_handle.INFO, LOG_RD, "End of File No data Received ......")
break
self.log_handle.log(self.log_handle.INFO, LOG_RD, "Reading Data is %s" % ch)
self.log_handle.log(self.log_handle.INFO, LOG_RD, "Closing Serial Port")
serial_uart_port.close()
return rcv

In my external libraries of pycharm, site packages are excluded. How can i include that site packages

Thanks and regards ,

Aneesh,

Your code runs fine after I installed "serial" package to project interpreter: https://www.jetbrains.com/help/pycharm/installing-uninstalling-and-upgrading-packages.html

Do you use the same interpreter in terminal and while running your code?

What do you mean by "external libraries"? Are they marked as excluded in project structure ("Settings | Project | Project Structure")?

Hello Yaroslav,

            Thank you so much for your reply. I found my mistake. It was on the configuration of interpreter.

Regards,

Aneesh

Aneesh,

You are welcome!
