Showing data change

[korenron]

Yes , this was my problem - didn't know how to associate data with ID

it's seem to be working - great !

Thank!

another small visual issue

it there a way to know what is the differnet and then paint it in color?

for eample
this is the reading (after the change you told me to do )

18FF20EF: 00 7d 00 00 7d ef 00 7d
0CD22F27: 40 00 00 00 00 00 00 00
18FEF117: 04 00 00 00 00 00 00 00
104C1A23: f7 0c f8 0c f8 0c f8 0c
0CFF104A: 80 00 00 00 00 00 00 08
104C1A23: f8 0c f8 0c f8 0c f8 0c
104C1A23: f7 0c f8 0c f8 0c f8 0c
104C1A23: f8 0c f8 0c f8 0c f9 0c
104C1A23: f7 0c f8 0c f8 0c f9 0c
104C1A23: f8 0c f8 0c f8 0c f9 0c

as you can see in massage "104C1A23" byte1 is "playing" f7-f8-f7....
is there any command that can comapre old to new - and point out only the differnet in color?

*** in the end I need a simple user to be able to see it right away ****



***

I have found this 
mport difflib

differences = difflib.ndiff('f8 0c f8 0c f8 0c f8 0c', 'f7 0c f8 0c f8 0c f8 0c')

for difference in differences:
    print(difference)

the output is

  f
- 8
+ 7
   
  0
  c
   
  f
  8
   
  0
  c
   
  f
  8
   
  0
  c
   
  f
  8
   
  0
  c

this is what I thought I can do:
1. I need it to take only the "+" ot the "-" - it's doesn't metter to me . then I will know where is the change
2. find the index if the cahnge in the new_data
3. color the index - and then print the new_data while the chagne is marked.

Thanks (again),
