I'm interested in the OLED choice and your interface. I thought you mentioned which AVR you use, but I don't see that detail either. --- End quote --- The OLED is a uOLED-128-G1 from http://www.4dsystems.com.au, which uses a standard UART for the command interface. This saves on pixel-drawing time since everything is done using higher-level commands (although I have successfully used other displays without affecting performance). As for the AVR, it's an atmega328p, which has 32K of flash and 2K of RAM, in a 28-pin DIP package. With three games, a frontend, and an RTOS, it's pretty much full to capacity. The joystick is a sealed dome switch unit which you can find at digikey (Part: EG4561-ND). It's wired up one line per switch (like the atari 2600) and the microcontroller polls the switches every frame. |

Pretty neat. I think you might be better off using 1/8" hardboard for the woodworking - the thickness of the sides are not in proportion to the size of the cabinet (and it looks like you are using 1/4" plywood which is thin to begin with!) . I am amazed at the creativity and ninja computer skills people have around here... :cheers: |

What? No Marquee? No Coin Door? Meh. <Just kidding> ;) That's an pretty dang cool project. What's funny is it's about the same size as those hallmark cabinet ornaments. Stick a hook in it and you can hang it on your tree come christmas! Add a christmas themed "attract mode" and presto! Playable conversation piece :) |
