Stuff to do!!! #14

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Below is the tasks that need to be completed this week by all group members:

1. Bake TCP Server into start-up (reliable and tested).
2. CMDreacon:
  a. H-bridge wiring
  b. Motor testing
  c. Wooden top cover thing...
  d. Arduino Sketch
  e. Raspberry Pi set-up
3. CMDoverwatch:
  a. Fix the wheels to the axil more reliably
  b. Finish off shaz-ie 
  c. Batteries
  d. secure the components to the board
  e. test steering
4. Python Scripts:
  a. TCP Server: Test and check multiple times that the thing is working correctly.
  b. Control Module:
     i. Joystick Detection (which one is it...)
    ii. Tidy code
   iii. Ethan's suggestion: Check direction through only two variables...so eliminate dir_y.
    iv. Fix the TCP server selection...doesn't seem to work any more.
     v. Less Questions to get to debug mode (Tom's suggestion).
5. Arduino modifications to account for the changes expressed above.

All to be completed before Monday 3rd December. (if Mr. S can find supplies and 
parts by then...otherwise, time allowances can be made.

I have successfully baked the TCP server into the Start-up process.  I did the 
following:

1. Create file "/boot/startup.sh"
2. Add the following text:
[ code ]

# CUSTOM COMMANDS TO START ON START UP
# Link with /etc/rc.locals

python /root/TCP.py

[ /code ]

3. Add the following to "/etc/rc.local":
[ code ]

su -c "/boot/startup.sh" root
exit 0

[ /code ]

restart and there we go... also not that when a disconnect occurs, the server 
is restarting! :D

I think we have success on "Thing to do: #1"

"Check direction through only two variables...so eliminate dir_y" I think 
rather the opposite of this needs to occur, particularly for CMDrecon because 
at teh moment we only have general direction we cannot control individual motor 
direction, something we need for pivot turning.

Anyways the other stuff definitely needs to be done!

How can I sent a loop so that if the server fails to connect a number of times, 
then it can say so connection...We need to check if the connection has succeed 
and then continue through to the script.

Currently, you can say that you **want** to use TCP server but if it fails to 
find the connection the 1st time, you have to start the script again.  If it 
was a fluke that you didn't find it the first time, we need say: 5 attempts at 
a connection before the script can decide to abort (where there should be a 
sys.exit so that errors do not occur).

The server will wait for clients though? It can't fail, thats only the client!

It will wait for clients to connect like before.  There is no checking for 
which client has connected.  This can come later.

Things to do in next update:
  - TCP Client - get rid of apostrophes for question about the Manual IP address
  - Chack which RPi is using Module.

The Hostname is only fetching the local host name not the remote.  This needs 
to be fixed.

socket.gethostbyaddr('<address goes here inside inverted commas> ')

>>> socket.gethostbyaddr('192.168.12.2')
('MAIN-WIN7-PC-LAN.fritz.box', [], ['192.168.12.2'])

look more at this for me...I will follow up tomorrow.

Issue with hostname fetching local name has been apprehended. We have replaced 
code with gethostbyaddr(HOST)
