Week 10 – 11/5/2004

     The code for the GPS portion of the project is currently at the point of converting character arrays to numbers for later analysis.  The trouble is the doubt of whether of not the character arrays received these values correctly.  Testing this will be the hardest part.  The solution we have is to search for the commas in the comma delimited code and display some indication of receiving those.  In the case of no signal we should be getting commas and nulls.  That will at least show that we can use the right registers and manipulate the data.  The LCD screen should be able to display all the outputs needed but no outputs will be available if no signal is received.  Work has begun on implementing the LCD/Keypad user interface module.  Over the coming two weeks, the LCD should be set up to display select outputs of the GPS.  This will greatly help testing/debugging of the GPS program code.

     The motor drive system is still having bugs worked out.  The needed timing is causing troubles.  This should be solved within the next week.
