Daedalus Firmware#

This directory contains the firmware for the RP2350 board.

Building#

Using the Makefile (Recommended)#

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)
2. Build the firmware:

   make
   

3. The output files will be in the build directory

Manual Build#

If you prefer to use CMake directly:

1. Configure the build:

   cmake -B build -S .
   

2. Build the firmware:

   cmake --build build
   

3. The output files will be in the build directory:
   • daedalus_firmware.uf2: UF2 file for drag-and-drop programming
   • daedalus_firmware.elf: ELF file for debugging
   • daedalus_firmware.hex: HEX file for programming with external tools

Flashing#

Using the Makefile (Recommended)#

Flash the firmware to the RP2350 board:

make flash

If the board is already running firmware and needs to be forced into programming mode:

make FORCE_FLASH=1 flash

Manual Flashing#

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

cp build/daedalus_firmware.uf2 /path/to/rp2350/

Or use picotool:

picotool load -x build/daedalus_firmware.uf2

Debugging#

Generate disassembly for debugging:

make disasm

Development#

The firmware uses both cores of the RP2040:

• Core 0: Handles the main application logic
• Core 1: Manages the LED matrix display

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