ComConsole:

• Made a library for the ComConsole, ComMgr, and Printable classes
• ComMgr’s sendData, recieveData, and toString were set to virtual
• Not sure why but, when I added the libraries to a new project, it complained about the libraries being in RELEASE instead of DEBUG.  They both worked in the other project and I couldn’t find any properties for this.
• Recompiled them as DEBUG

DataDictionary:

• Changed all instances of 32-bit integers to 16-bit so the Arduino matches up.
• Added type parameter and associated methods to DataElement.

Serialization/Deserialization:

• Figured out how to extract data from the receive buffer.
• Tested the PC side Serialize and De-serialize.
• At first I was copying the DataElement out of the buffer but eventually figured out how to read it straight from the buffer
• Started writting a method for the arduino to Deserialize.

C++ Libraries

• Just use the .h files from the library source.  I thought they had to be special.
• If you don’t want to change a bunch of properties you can drop the .lib and .h files in the source root directory
• Phil recommended making  include and lib directories in the source folders to help with organization.
• On the arduino side it seems you cannot use pre-compiled libraries.  I looked all over and could not find one example of someone who used anything but the source.
• Put the source into a folder and then drop it into the libraries folder of the arduino IDE.
• Make sure to disable pre-compiled headers for non-windows libraries.
• new and delete are not defined properly in the arduino IDE.  The following is needed for these functions to work properly.

#include <stdlib.h> // for malloc and free
void* operator new(size_t size) { return malloc(size); }
void operator delete(void* ptr) { free(ptr); }

Communication:

• Setup serialization methods to return a char*.
• Changed getData to have a special case for remote data which it handle differently.

Creating a Library:

• Compiled the Library to a .lib file
• added references to the project properties
• Tried a few different things to get this to work right.  I think the main problem is that I was not making the .h file right.  I found this post which may help: http://forum.codecall.net/c-tutorials/3539-how-make-use-library.html

Com Console:

• Got a bit annoyed with the Library not working so I decided to continue setting up the Com Console for when I have the Data Dictionary in it.
• Made it so all the data elements of command and response were in a struct and changed the set get methods to work with this.

End: 6:30

6/19/2011 Note: I tried the library again on Sunday.  Its not giving me compiling errors anymore but I haven’t really tested it yet.  I will try to test it tomorrow.

Start: 10:00

Data Dictionary:

• Found that you can’t compare char* directly.  First tried strcmp(char* first, char*second) but found this only compares the first char in string.
• strncmp(char* first, char*second, size)  is the way to go.  Was originally using a defined maximum but Phil told me it would be better to make sure the string length is equal first then set the size to the string length.
• getData(char* name) implemented
• deleteItem(char * name) implemented
• added toString() to print out current contents

Com Console:

• Cleared all test code
• Added sendBuffer and recieveBuffer to ComMgr
• Added toBuffer methods to command, response, and state classes.

End: 6:30

Data Dictionary:

• Had very strange compiling errors.
• Moved project to its own solution.  Problem was not resolved.
• Eventually realized that DataElement.h was missing a ; at the end.
• Changed addItem and DataElement to have the void* to the data in their parameters/constructor.
• Changed addItem to return void.

Arduino to PC Communication:

• Was able to pass a structure back from the arduino
• recieveData gets the buffers pointer and writes to the buffer.
• To make testing easier all this is still done within the ComMgr.

Data Dictionary:

• Phil helped set up the data dictionary.
• use strcpy(des, ori) to copy a char*.3
• Anytime malloc or new is used, remember to free resources.
• Still not sure how data is put into the data elements.
