Start: 10:00

• Fixed a problem with PC receive method.
• Fixed the deserialization method.
• Single pass works both directions.
• Found a problem with the states that was causing it not to loop properly.
• Changing the code to receive sensor data and have the pc respond with commands to the arduino based on the data.
• Commands will light 5 leds based on the pressure of the sensor.

End: 6:30

Start: 10:30

• Add a method to get the total size of the data element with the data so it could be loaded into the buffer easier
• Was importing the size into the buffer which was causing the deserialization to not work correctly on the arduino side.
• Arduino side is able to get data from the wire.
• PC recieve doesn’t seem to be working correctly for DataElements

end: 6:30

Start: 10:30

• Continued writing test application
• Tested it but its not working.  Wire lights light up but the data isn’t going to the right place.

End: 2:30

Left early to go on a camping trip.

Start: 10:30

• Edited the de-serialize method on the pc side so it should work with wire data.
• Changed the size to be type char for now so that I didn’t have to worry about it being a 2 byte integer
• Changed how receive data worked
• Started writing a test application to send commands to the arduino and have them echoed back
• Added states to the pc test application

End: 7:30

Start: 10:40

Arduino Communications:

• Wrote a sketch to handle the communications and deserialization on the arduino side
• Everything should work but I need to fix the PC side deserialization which is currently setup as a test method
• Once I know all the methods work I will put them into a ArduinoCom library to keep the main sketch from getting cluttered
• sendData may need some stuff added to it.

Notes:

• It is fine to send the DataElements individually instead of one buffer which is how I thought it had to be done
• Serial.write needs a uint8_t* to the buffer.  I figured they are both 8 bit pointers so I just casted my char*.

End: 5:30

Have to be somewhere at 6:30 will make up the extra hour and change tomorrow.

Start: 10:10

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.

End: 6:30

Start: 10:00

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.
