|Chapter 4 - Conclusion and Evaluation|
Interfaces are an important part of all our lives even though very few people
operate them directly or even know that they are there ! ElectroMac has a PIC
microcontroller inside it allowing it to communicate with the Macintosh computer
and receive signal from the electronic circuits.|
There is a standrard set of commands which are sent to ElectroMac instructing to to perform fuctions or return information. These are then available at a higher level programming language in the form of a series of subroutines written in C++.
The interface ended up fairly close to the original idea and specification. I
ended up not looking at other interfaces and interfacing other computers, but
studied my own interface more closely. I did however write a section on very
basic interfacing and its every day uses in the background section of the first
I did not have enough time to do much work on analogue due to more complex electronics and thus I did not write very much about it in the report. This is also true of data logging, another proposed original idea. The idea of connecting the model house to the interface was not in the original plan but seemed a good way of demonstrating the interface's capablilities.
The investigation provides a good overview of ElectroMac but could be improved by providing a bit more information about other interfaces available and the problems (and solutions) of interfacing the Macintosh.
