Solutions
How We Built It
Our Approach
Dual-Controller Embedded Architecture with Custom C Modules and I2C Audio
The system was built using a dual-controller architecture combining the SAMD51 and ESP32 platforms to handle different aspects of processing and communication. Custom C modules were developed to optimize performance within a MicroPython environment, improving execution efficiency for real-time gameplay. The audio subsystem was designed using I2C communication along with DAC and amplifier integration to provide responsive and high-quality sound effects. The overall architecture ensures smooth interaction, synchronized gameplay, and reliable performance across all components.

Client Feedback
What the Client Said
"
The responsiveness was the thing we were most worried about — any lag in a two-player game kills the experience entirely. There's none of that here. The controls feel instant, the audio hits at exactly the right moment, and the whole thing holds up through extended play sessions without a glitch. It doesn't feel like a prototype — it feels like a finished product.
