A simple resistive DAC is all you need to drive a VGA display. Combining that with an on-chip DAC for audio, the STM32F405RGT6 looks like a good choice for a DIY game console. [Makapuf's] Bitbox console is a single chip gaming machine based on the STM32 ARM processor.
We’ve seen some DIY consoles in the past. The Uzebox is a popular 8 bit open source game system, and [makapuf] was inspired by its design. His console’s use of a more powerful 32 bit processor will allow for more complex games. It will also provide more colors and higher quality audio.
One of the keys of the Uzebox’s success is the development tools around it. There’s a full emulator which allows for debugging with GDB. [Makapuf] has already built an SDL based emulator, and can debug the target remotely using GDB. This will certainly speed up game development.
After the break, check out a demo of the first game for the Bitbox: JUMP. Also be sure to read through [makapuf]‘s blog for detailed information on the build.
