SpotShooting

I tried to implement a shooting game with Sun SPOTs. Three Sun SPOTs are used. The first one managed a bitmap LCD display through the outpins expander. The second one is used for a game controller. The last one is a sound server. I want to show Sun SPOTs can do all things PCs can do.

Yes ! I have met you several times at JavaOne and Sun Labs when I've visited. Thank you.

Thank you for your comments and questions. Display SPOT is processing almost all of the game logic. I think this SPOT has a enough processing speed, but the display is slow. There is a bottle neck between Display SPOT and the bitmap LCD. The output pins are expanded to control the LCD using a lot of latches and the SPOT has to send many commands and display data to the LCD. If I can connect to the LCD more directly not using output pins on the edemo board, the display speed will be improved.

More details please on what SPOT is doing what?

1 - Game controller

2 - Display

3 - Sound

Which one is doing the game logic?

Have you identified why the display is slow? Is it the bandwidth to the display?  Or is it the speed of sending the pixels through your code?

Is there anything we can do to help you with figuring out the bottle necks?

This is WAY cool BTW, Space Invaders on SPOTs :)
