Turbo Charge your Uzebox: Upcoming ATmega1284P

Wow, I just noticed Atmel is about to release the ATmega1284P: 20Mhz, 128k Flash and 16K or RAM, an extra 16-bit timer...and it will be available in DIP! Same pinout, so its a direct replacement for the 644. Now we are talking serious games here! :D Digikey already list those, so I hope they are com...

Re: programing the atmega

The thing is that I don't live in the us, so don't want to order there.
Where do you live? Because Digikey is present in many countries: us, canada,uk, japan, germany and korea. They have specific site and prices for these countries.

Re: ATmega644

You should use the 644.
In fact, you must. The ATmega644 is, as far as I know, the only one with decent memory (>2K RAM) in a DIP package. And more importantly,its rated at 20Mhz to reliably overclock. The mega32 and 128 are 16Mhz devices.

Re: NES Controller replacement

From the point of view of the ATmega input pins, its the same thing to have the 4021s on the board or in the NES gamepads. Same latch, clock and data pins. Naturally you can not have both at the same time. I assume that someone will wire its board for only one type of controller. A PCB should accoun...

Re: NES Controller replacement

I was not sure if this part was made anymore. So let's do it this way then. If wired correctly, it will support both NES and digital joysticks with no change at all to the software! I'll order parts to test this let you know how it goes. Then I'll add it to the schematic.

Cheers,

Re: Uzebox PAL support

The problem will be the kernel's video timing interrupt, its very precise. One cpu cycle more or less and the image screws up! :?

Uzebox PAL support

Anybody interested in porting the Uzebox to PAL? The AD725 supports it with a simple logical pin.In fact, most work would have to be done in software. I'm sure someone would be willing to do it (like me :P ), but where can we get PAL enabled devices in north America?

Re: PCB or stripboard layout

Very nice! Can you generate Gerber files so it could be manufactured with silk screen and green mask for that ultimate pro look? Also, what PCB tool do you use?

Cheers, and thanks for sharing!

New Features Incubator

This topic is open for new hardware features discussions. So far, from the forums, some winners arises: 1. SD card interface: Would allow some cool stuff like being able to reprogram games without connecting to your computer. And wouldn't it be uber-geek to play your favorite (decompressed) mp3s for...

Re: Official parts list

Geez, thats bad, they usually always have this programmer. I guess there was a sudden rush due to the Uzebox ;) . There's always the good 'ol ATSTK500-ND (which I use) , you can do more with it, but its also a bit more expensive. Otherwise Mouser Electronics has it in stock. Anybody know of another ...
