GameToy hardware project

These pages describe a sort of blog-ish time log on my 'GameToy' hardware project (stalled indefinitely).

September 3rd, 2006 - Laura

School started, and I'm using the Laura (audio) bit as project in 'embedded programming' course.

The last time I touched the project, I tried to get the audio to work on hardware, and ended up with horrible distorted noise. I started over again with the Laura integration by updating the cross-platform build environment so that I can play audio with SDL as well, and, as you may have guessed it, the distortions were there on the desktop as well.

It ended up being some kind of small integer value overflow, and once I got it fixed on the desktop, I got the hardware working as well.

Took the 'game controller' apart to be able to make a somewhat more mobile demonstration version of Laura:

Running at 22Khz, I'm only able to use two channels. Even though I doubt the 'final' version will use such a 'high' sample rate, I definitely have to look into writing things in assembler on this platform.

Comments are appreciated.
