Re: Thinking about STMUzebox

So, forget 15-bit color. Now, I'm proposing 12-bit color. That's still more color depth than the Sega Genesis and it still allows for even color channel lengths. Plus, you could pack two direct colors into three bytes with minimal effort. 12-bit color can produce some pretty nice results. Even in C...

Re: Another inspiring project

Wow. That is very cool. It'll be useful for anyone who wants to play with a big frame buffer. I like the way the CPU is external to the design, so you could have a cartridge-based system with different CPUs (AVR, PIC, ARM, etc.) on different games.

Re: trying to build from makefile on osx

Hi, I think no one was using Mac until now. At least since I worked on the Uzem, no one give me feedback about the build system changes. About the error, the compiler is complaining about the mmap.h file. For linux is being included the mman.h, I don't know which one is used in Mac OS, but... Mac O...

Re: Atmega1284P Test Results!

Has anyone tested the ATMEGA1284P? Well aside from Uze. Mouser has them in stock and I was thinking of ordering one. This is my first Uzebox and I figured the extra ram would be nice. They have the QFP package (ATMEGA1284P-MU) in stock. I'm waiting for ATMEGA1284P-PU (the DIP package) to be in stoc...

Re: which kit to go with ?

It's pretty trivial to disable and overwrite the bootloader on the fuzebox. (just change the fuses, then program it with an ISP programmer.)

fuzebox may be upgradable to an ATmega1284 at some point in the future, if they ever ship the damn things (and if they can be overclocked reliably)

Re: Uzebox SD Gameloader Alpha...at last!

Onto another subject. One thing I wondered for a while. To the Fuzeboxers outhere: you guys are using the FTDI cable to flash the chip...to use this bootloader you'd have 2 choices. 1.Buy a SPI programmer or 2.buy a new mega644 with our new super-duper bootloader and *ideally* FTDI support also (bu...

Re: Uzebox / Digital Photoframe Love Child

think you could hijack the SD slot as well? That could make this thing really convenient... (well, once the SD bootloader is complete, obviously)

Re: Bootloader

There's just one problem with this. The 644 has built-in protection against overwriting PGM space if the program counter is *outside* the specified bootloader space, however big that is. This partitioning, and the size of the boot area is controlled externally by the fuse bits. So I think that you ...
