Week 6

Digital Compass Aspect

The Dinsmore 1490 digital compass has been successfully implemented with the Zilog Z8.  The directional

output is displayed to the four 5x7 LED's on the Zilog Z8 development board.  The sensor mount and wiring

 used in connecting the compass to the Z8 board is only for testing and is not the final setup.  In the

next week, the specific registers in which the compass data is stored will be researched so that the GPS

portion of the program will be able to access that data to compare it against the GPS directional data. 

GPS Aspect

Progress:

- Downloaded sample code for the microprocessors UART.

- Figured out the register name where data is stored when coming in.

       - Will have to come up with an algorithm for filtering data in this register.

- Learned that GPS data is comma delimited.  Will have to filter commas to get correct information.

To do:

- Understand more of the sample code.

- Come up with an output so that I can see data entering microprocessor.

- Use that to create code that is more in tune with GPS.

- Get hardware for testing the GPS.

Motor Control Aspect

Progress:

- Continued research on using Zilog Z8 to replicate control signals.

- Attempted implementation of Zilog Z8's timers using sample code.

To do:

- Continue reviewing sample code in order to implement using Zilog Z8.
