After reading these directions, please delete them:

1 – Go over ALL the recordings for iLab6

2 – Use the start-up code that has been provided to you. Remember that the code will not compile as-is … You have to add a delay() function call. A delay of a few milliseconds will suffice

3 – Along with this document, please submit a .ZIP file containing the directory structure with all the project and source code files (in other words EVERYTHING that I need in order to run and download your design project). Name the file iLab6_YourLastName.zip, and upload it dropBox, along with this document

4 – Once you are sure your Lab Report is complete, remove these lines, save and upload your document to the dropBox (if possible, try to submit this document as a PDF file).

5 – Make sure your iLab is formatted properly, and looks pleasant on the eye

6 – Please read this - The code that prints the character to the LCD must be in main(), not in the ISR. Also, your code must make sure that a key is printed only once – In other words, the key has to released and then pressed again for the same character to appear on the LCD. The easiest way to proceed about this is to have the ISR raise a flag. Function main() monitors the flag. If the flag is raised the character is printed, and the flag is cleared.

7 - For iLab6A, is there a way, through the debugger, to modify the variable that you are sending to the SCI module? Or, is there a way to modify the contents of the appropriate SCI register? What would this register be?
