PicoRuby currently has two major implementations: PRK Firmware and R2P2. PRK Firmware serves as a keyboard firmware, while R2P2 can be used as a general-purpose electronics platform. Can these two be integrated? In other words, if R2P2 is a general-purpose electronics platform, wouldn't it be possible to write keyboard firmware using R2P2? In practice, there are several hurdles to achieving this integration. In this session, I will discuss the work I have been doing toward this integration.
