Here is our AVR project we are working since late 2011.
It is something like Rapsberry Pi but 8bit.
It is based on Jerry´s AVGA platform.
(He is also behind all RetroWiz hardware, HW designer).
I am WWW and FORUM admin, enclosure designer.
We call our platform RetroWiz. (from "Retrocomputer Wizard" or "Retrogaming Wizard").
PCB half size of Raspberry Pi...
172x200 x 16 colors
simple FM synth codec
menu and firmware on chip
20 mhz/8bit risc cpu (ATMEGA328)
stereo audio out
PS/2 keyboard port for keyboard or arcade joy hacks
C language API
SD card port
It will be awesome platform for FM music, pixelart, retrogames, indiegames, coding...
Join FORUM, join DEVELOPMENT and welcome to RetroWiz world...
@jmetal88 - Yes we use very similar palette to EGA/VGA card.
Here is our hardware defined palette (we loved PC MS-DOS games era):
@Amstari - UZEBOX is more powerful in graphics because they use PAL-NTSC.
Why VGA? Simply on every modern TV or MONITOR there is VGA connector,
plus you can buy old LCD or CRT for 5USD-3EUROS /second hand/.
But main reason is that on VGA monitor there is better pixel graphics.
Maybe we will add TV encoder in future and we will be able to have
344x400 on PAL or NTSC TV (we had some prototype tests on TV too).
Maybe there will be RetroWiz TV version with
composite output. RetroWiz will have OPL FM not PSG like UZEBOX. So
sound will be like on SOUNDBLASTER,ADLIB,SEGA MEGADRIVE,JAGUAR
but only 3 channels mono... So there will be better sound than UZEBOX:
So first we will release VGA version and than TV version...
There will be also JAVA music editor and JAVA or FLASH emulator .
A BASIC would be a good stopgap measure between now and having a simple dev kit. It would give noobs like me a way to make something and run it without too much hassle.
VGA is a very good idea I wouldn't have thought of. I have two CRT monitors at my parent's place that we cannot figure out what to do with. This would be awesome!
Any chance there could be a way to hack a serial game pad into the ps/2 slot? This just begs for a Gravis Gamepad! Ah, memories!
You might consider trying to hock this at universities with strong electrical engineering or computer science programs. It might be nice if students could program for a standardized device and be able to swap source files that will work without modification.
We have toons of spam registred on forum each day.
I chceck out new users day by day and look into spam ban databases...
So any new user - please send me here PM+register on forum. And I will approve you.
We are running 172x200 now... Still optimizing code. Web and social networks will be soon.
