Re: OK, new idea. (UZEBOX Stamp?)

I just read PSX docs and I think I got over exited a bit. Its much more complex both in term of protocol and cycle count. I'm really divided on that joystick issue! It's Uze's baby though, so whatever he thinks is best! I'll use that Joker up my sleeve then ;) . We have to act soon while peoples are...

Re: New Features Incubator

For the universal joystick interface, I need to define a standard button mapping to establish compatibility and shield games from having to support many joysticks. Read this post for more details: http://uzebox.org/forums/viewtopic.php?f=1&t=23#p160 So far I have: -Nes -Snes -Genesis -PS1 -PS2 -Two ...

Re: OK, new idea. (UZEBOX Stamp?)

Sweet, the stamp appeals a lot to me. Imagine pop in one of those in your next project and voila, instant video and sound! I don't think I ever saw that anywhere! I could see these little guys being hot ticket items for all hobbyists. I think that many embed applications would benefit from an instan...

Re: Video DAC suggestion

Do you think it wise to mandate some sort of 'minimal joystick API'? Like maybe just define a mapping for the UDLR/B1B2B3B4/Start/Select buttons in a couple bytes so that the PSX or NES or Genesis pads could all look the same to game code for basic functions? IMHO, the lack of "governance" on some ...

Re: Uzebox PAL support

I was looking at the AD725 doc and realized that for PAL it requires around 18Mhz. Doubling that, as required by the software, would give ~36Mhz! I didnt' try it, but I seriously doubt the mega644 will work at that speed. So the only other alternative would be to develop something for the RGB SCART ...

Re: Any objection to the AD723?

I don't have any! Its functionally equivalent, smaller and cheaper, so go for it.

Re: Light gun input?

Hi Clay, thats a neat idea. Unless there's a hardware way to stop a timer on interrupt, its impossible to detect X position during rendering without screwing up the picture. That's mainly because 100% of cycles are used during rendering scanlines and the unpredictability of the interrupts latency. H...

Re: Video DAC suggestion

Hmmm... wait a sec, theoretically a SD interface on the AVR via SPI could support a bitrate of CPU freq/2 no? Thats 14 megabits/sec or ~1,7 megabyte second. It would be in raw sector mode but with a raw mode write tool, who would care? 8-) I'll read the ps2 docs tomorrow but so far, you sold me to t...

Re: Video DAC suggestion

I was going to put down a triple RCA for composite video + stereo (well, dual mono) audio, a DIN 5 for MIDI, and a mini-DIN 4 for Svideo. I love it, specially the svideo! You're really putting the cream of the crop in there. I haven't look at it, the playstation joystick interface, is it a serial i...

Re: New Features Incubator

SD card may be coming very soon . Right now, it's a bit awkward. Maps need to be created in Photoshop/gimp, converted to the Uzebox palette, exported as raw bitmap and converted to map/tile using a custom Java tool (mainly to be cross platform). Since I needed 6x8 tiles, there's was no existing tile...
