Hi Mayur,
Updated the DictionaryDemo in CVS. It should now compile
(it won't actually work yet - explanation in a moment) in
TinyOS 2.x as long as you have the following directories
included (all from the rincon contrib directory in 2.x
cvs):
* /tos/lib/blackbook
* /tos/lib/blackbook/boot
* /tos/lib/blackbook/core
* /tos/lib/blackbook/interfaces
And platform-specific DirectStorage implementations:
* /tos/chips/at45db - for mica*
* /tos/chips/stm25p - for telosb's
It's going to compile, but there are bugs inside of
Blackbook still that prevent it from working correctly.
What should happen is, everytime you reboot the mote,
your leds increment to show you how many times the mote
has been rebooted. Right now it's getting stuck.
We have been actively working on fully debugging Blackbook
and are making a lot of progress. In fact, this problem
may already be solved and we'll need to update the contrib
CVS. A full working version of it should be available
late January/early February. Right now, it's best not to
try to get a system fully operational using the current
Blackbook 2.x file system implementation because of the
current bugs; however, my team is moving forward with
deployments. These deployments are scheduled to be
released toward the end of February that are dependent
upon the Blackbook file system. We're building the
applications using the Blackbook interface while knowing
we won't be able to fully plug it in until later on this
month.
Blackbook will do everything you want it to do below,
except delete the data that your mote already sent. This
is a property of flash, you can write at the byte level
but have to erase at a much larger size (typically 256
bytes - 65535 bytes at a time). If you're interested in
implementing a circular buffer to store data, you should
take a look at the LogStorage interface.
1. Create a file
- BFileWrite.open()
2. Start writing some data
- BFileWrite.append()
3. The other module will access this file
- BFileRead.open() / BFileRead.read()
4. Find the read pointer to start reading from the point
left on an earlier occassion and sending the read data over
the radio
- BFileRead.seek() / BFileRead.skip(), but
BFileRead.read() will automatically continue reading where
you left off last time as long as you don't close the file
in between.
5. The sent data after confirmation from the acks will
need to be deleted.
- Can't delete data out of a file once it's been
written. You'll need to close the file, delete the file,
and re-open the file if you want this type of behavior.
Hope that helps,
-David

Hi David,
I have started building the application which will use
the interfaces
provided by the File System.
I am using two modules wired together which will do the
following:
1. Create a file
2. Start writing some data
3. The other module will access this file
4. Find the read pointer to start reading from the point
left on an earlier
occassion and sending the read data over
the radio
5. The sent data after confirmation from the acks will
need to be deleted.
Let me know if we have the preceding interfaces which
can be used by the
modules.
I started using BBFS but the first part of the problem
came when I did "make
telosb" of the DictionaryDemo App in its respective
directory. I have copied
the errors. I am using cygwin and the directory
structure is like this:
/opt/msp430/..
/opt/tinyos-2.x/..
/opt/tinyos-2.x-contrib/rincon/..
I got the following errors and I am quite sure that the
environment
variables are not set at all for the Contrib directory.
Other TinyOS 2.0 apps
are compiling correctly. Let me know the if this is due
to not setting the
environment variables.
