"Raspberry Pi Pico: From Unbricking Wii U to Building Supercomputers"
The PicoCray project connects multiple Raspberry Pi Pico microcontroller modules into a parallel architecture leveraging an I2C bus to communicate between nodes. Each processor node implements a random back-off technique to request an address from the controller on the shared bus. Once a processor node has an address, it can be sent tasks from the controller node, such as computing elements of the Mandelbrot Set. The controller node collects the results from each processor node and aggregates the results for display.
