GameToy hardware project

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

June 6th, 2006 - Hardware

After rather many false starts, I finally got some life out of the LCD. Here's some webcam lovin' for you:

So. I rewired the LCD about six times, checking for bad connections, shorts, etc. Searched the web for other people who have played with similar displays, finding a couple, but their code did not show anything I hadn't tried.

Searched for more data sheets. Figured the problem might be with the header connection, so finally decided to solder it in. No help. Started wondering whether the screen is dead.

Then I debugged the outgoing signals, and found that the port I was using wasn't working as I expected, since the JTAG interface was enabled. Since I'm not using it for anything (having no JTAG), I disabled said interface.

Now the display at least turns on, and I can see some action going on on the screen, but not exactly what I expected. One of the other people's projects, when copied to the AVR, does show something sane, so I have something working to compare my code with.

Comments are appreciated.
