LEAP#100 Retrogaming on an Arduino/OLED "console"
Tiny 128x64 monochrome OLED screens are cheap and easy to come by, and quite popular for adding visual display to a microcontroller project.
My first experiments in driving them with raw SPI commands had me feeling distinctly old school, as the last time remember programming a bitmap screen display was probably about 30 years ago!
So while in a retro mood, what better than to attempt an arcade classic? At first I wasn't sure it was going to be possible to make a playable game due to the limited Arduino memory and relative slow screen communication protocol.
But after a few tweaks of the low-level SPI implementation, I was surprised myself at how well it can run. Even had enough clock cycles left to throw in a sound track and effects.
Here's a quick video on YouTube of the latest version. ArdWinVaders! .. in full lo-rez monochrome glory, packed into 14kb and speeding along at 8MHz.
