Results of Design

Problems

•  Initially, we were assuming constant time between the bits from the controller (i.e. assumed that every bit is sent 4 microseconds each). This causes many timing issues that we were not able to read the correct data. We decided to change our detecting method to detecting every falling edge in the signal.

•  The LCD display was broken that only half of the screen was working. There was no replacements in the lab and we ended up using only the first half of the screen.

•  There was also synchronization problem with the LCD display. We had to attached an RC circuit to the synchronization signal and use function generator to predict the right sync frequency

•  The sensitivity of the controller joystick prevents us to create high resolution on the different speed of the ship.

Conclusions

It is certainly possible to create a game console with the current setup. All left to do is the create a powerful graphic library. The logics for the game is easy. For better results, better LCD display(preferably color) would make everything more attractive. Having the experience of creating a game like space invader and oscilloscope, making a more interactive software games and tools does not sound hard at all.
