Hi, I am using a
wireless modem which is connected with FTDI32 chip. The modem is receiving the values from Wireless Temperature sensor.
I am working on a project in which I want to receive the values of the wireless sensor which is transmitted to the wireless modem in my laptop and with the help of python code, I want to convert the data and display in my message box.
As in mentioned below manual, there are different registers which contain hexadecimal values and I need to store the register values in different variables using python
Any suggestion on this will be a great help.

Hi, Actually, I have created this code in which I am receiving the data from Arduino using serial communication in string format.
import serial
ard = serial.Serial('COM4', 9600);
while True:
k = ard.readline().decode('ascii');
print(k)
I want to store the information in 3 different python variables. Do I need to use a buffer to store the received data? how will the code be?
According to my search on the internet, the buffer is used to slice the string.
As beginner python world I need some suggestion which helps me to create the temperature monitoring system.
Will be looking forward to your advice on this.
It depends on what the contents of k are here. For example, you could do something like this
k = "1,2,3"
a, b, c = k.split()
Make sure to provide enough detail for us to help (e.g. what k looks like).
Thanks for the help, Actually I am receiving the data as mentioned below
hello\r\n
hello1\r\n
hello2\r\n
I just want to store the data in such a way that
>hello will be stored in variable a
>hello1 will be stored in variable b
>hello2 will be stored in variable c
and the \n\r will be minimized from the serial data
jenkins43 Wrote:>hello will be stored in variable a
Store it in a dictionary,that's what Python dos
If look closer at it when do
a = 'hello'
,so do Python store this is in
globals()
dictionary.
>>> a = 'hello'
# how it look in globals
'a': 'hello',
# Use this dictionary
>>> globals()['a']
'hello'
So this make a visible dictionary record.
import io
# Simulate serial data
ard = io.StringIO('''\
hello\r\n
hello1\r\n
hello2\r\n''')
record = {}
lst = ['a', 'b', 'c']
while True:
k = ard.readline()
if k == '':
break
try:
if k == '\n':
pass
else:
record[lst.pop(0)] = k.strip('\r\n')
except IndexError:
pass
Test:
>>> record
{'a': 'hello', 'b': 'hello1', 'c': 'hello2'}
>>> record['b']
'hello1'
>>> record['c']
'hello2'
