       The project includes a Makefile that simplifies the build process:

       1. Make sure you have the Pico SDK set up (automatically handled by the Nix flake)

          ```

       18
       32
        
          - `daedalus_firmware.elf`: ELF file for debugging

     

       19
       33
        
          - `daedalus_firmware.hex`: HEX file for programming with external tools

       Flash the firmware to the RP2350 board:

     

       40
       40
       +
       

     

       41

       45

       Connect the RP2350 board in bootloader mode (hold BOOTSEL while connecting USB) and copy the UF2 file:

       75
       +
       The firmware uses both cores of the RP2040:

     

       76
       76
       +
       - Core 0: Handles the main application logic

     

       77
       77
       +
       - Core 1: Manages the LED matrix display

     

       78
       78
       +
       

     

       79
       79
       +
       The LED matrix is organized in a 4x6 grid, with rows and columns controlled by GPIO pins.
