It uses best of breed components and strives to keep 8-bit feeling, while being usable for daily basis computing activities.\n\n## Dev Setup\n\nThis is only for building the RP2350 software.\nFor writing 65816 CPU software, see [rp6502-vscode](https://github.com/picocomputer/rp6502-vscode).\n\nInstall the C/C++ toolchain for the Raspberry Pi Pico.\nFor more information, read [Getting started with the Raspberry Pi Pico](https://rptl.io/pico-get-started).\n\n```\nsudo apt install cmake gcc-arm-none-eabi libnewlib-arm-none-eabi build-essential gdb-multiarch\n```\n\n```\nsudo dnf install cmake gcc-arm-linux-gnu arm-none-eabi-newlib gcc-c++-arm-linux-gnu\n```\n\nAll dependencies are submodules. The following will download the correct version of all SDKs.\nIt will take an extremely long time to recurse the project, so do this instead:\n\n```\ngit submodule update --init\n```\n\nTo debug Pico RIA or Pico VPU code, you need a Debug Probe or a Pi Pico as a Picoprobe.\n\nThe Pi Pico VSCode Extension will need this additional software:\n\n```\nsudo apt install build-essential gdb-multiarch pkg-config libftdi1-dev libhidapi-hidraw0\n```\n\nCreate `/etc/udev/rules.d/99-pico.rules` with:\n\n```\n#Raspberry Pi Foundation\nSUBSYSTEM==\"usb\", ATTRS{idVendor}==\"2e8a\", MODE=\"0666\"\n```\n\nDebug terminal:\n\n```\nopenocd -f interface/cmsis-dap.cfg -c \"adapter speed 5000\" -f target/rp2350.cfg -c \"program build/src/rp816.elf verify reset exit\"\n```\n\nConsole terminal:\n\n```\npicocom -b 115200 /dev/ttyACM0\n```\n\nWSL (Windows Subsystem for Linux) can forward the Picoprobe to Linux:\n\n```\nPS\u003e winget install usbipd\nPS\u003e usbipd list\n\nPS\u003e usbipd wsl attach --busid 7-4\n```\n\nWSL needs udev started. Create `/etc/wsl.conf` with:\n\n```\n[boot]\ncommand=\"service udev start\"\n```\n\nVSCode Serial Monitor doesn't yet send breaks or let you slow down a paste. Minicom is still useful\\.\n```\n$ minicom -c on -b 115200 -o -D /dev/ttyACM0\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fx65%2Ffirmware","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fx65%2Ffirmware","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fx65%2Ffirmware/lists"}
