Gameplay w/accelerometer
« Thread Started on Jul 29, 2006, 1:05pm »
Here's a video demo of myself playing Markanoid (poorly :P) using an accelerometer as controller:

http://video.google.com/videoplay?docid=-3837870026578624247

Although the game was modifed for the Hummer, as discussed in the 2d-3d controller thread the 'digital joystick mode' would enable any DTV with a joystick port to play unmodified games with this device.

MArkanoid was an entry in the minigame comp by Stefano Tognon.

Cool. Youd be better off with a Gyro sensor wired to the hummer analogue input :) Absolute positioning of the paddle with the amount of tilt would be amazing.

My accellerometer should be here soon, curse you for pointing out that cool toy. I wish id got the i2c one not the analogue one now though.

Lots of strange sensors are collecting on my pic proto board now, the hall effect sensor is great fun!

Got a colour nokia LCD coming soon too.

I'm not a game designer, and I'm afraid unless you program your own custom games, gyros would just be wasted on the DTV. You can get joystick-like movement even from a 2d accelerometer.

But for non-game apps, data aquisition, etc. I'd love to play with one. But they are expensive.

RE: the Hummer ADC--it's sample rate is ~ 25kHz (8 bit.) The AVR's rate is 200kHz (10 bits.) If you don't care about loosing resolution (dropping a bit or two), I bet you can up the AVR sample rate to 500kHz or more. With unused channels, it's not like I need the Hummer ADC, anyway.

I'm not saying don't use the Hummer's ADC, but just be aware of it's limitations.

I looked at i2c versions also, and they are pretty cheap. But the one company wanted $25 USD just for shipping a sample!!!! There are speed issues, and I'm surface-mount challenged....

I should clarify:

I AM using the 'digital joystick mode' to play this game on the Hummer. The game is modified only as far as substituting the userport addr for the joystick port.

No software drivers are employed on the Hummer. The work is all done by the AVR.

The downside is that it's no longer an analog device with absolute positioning. The upside: as I said, on a DTV with a joystick port, ANY GAME WILL WORK.
