Future Work

Future work for this project would entail completing the programming of the microcontroller. Some code has been written to control components such as the real-time clock, the LCD, and the memory, but much testing of those still remains.

Errata List

• Possible bad connection between the power pad on the DC connector footprint and the power plane.
• Poor orientation of the right angle potentiometer (R7) controlling the contrast of the LCD makes the contrast difficult to adjust. A rotation of 90 degrees counter-clockwise would be sufficient to correct the problem.
• Pin connection problem associated with memory access by microcontroller (U8). The address lines of the microcontroller were used to access the SmartMedia. This means the microcontroller must actually be put in a mode to use those pins to address external memory. A side effect of this is that two pins on the port C will be taken over by the microcontroller for administrative purposes. Unfortunately, those pins are being used for I/O functions on other parts of the board. In future revs, a solution to this issue must be found.
