8:00 – 4:30 FP

• The kinetic sculpture race was a blast. Here are pix: http://www.flickr.com/photos/21701734@N04/sets/72157629972340647/
• Let’s see if we can get sound working today!
• And now a short pause while we install video driver updates…
• Looking through the port_test code
• Having problems with the serial code again. It appears that the arduino is getting into a condition where it thinks that there is always a character waiting to be sent
• I’ve gone back to the test harness, which is having the same problems. It appears that there is something wrong with the workingBuf[]. If I don’t put characters into it, then the rest of the code works fine. Nope, it seems fine. Moving onto the aJSON and DataObject classes.
• aJsonObject* jsonObject = aJson.parse(workingBuf); and aJson.deleteItem(jsonObject); seem to reliably crash things. I think it’s a memory leak. That would explain the randomness of the errors.
• Putting a parser in the BaseDataObject class. Going to see if I can use this hashmap: http://www.arduino.cc/playground/Code/HashMap
• I really can’t believe I’m hand-rolling a parser. Ah, well. Onward.
• Built a DataElement class (with static declarations!) Handles char[16], int and float. Mostly done. Integrate with HashMap and test tomorrow.
