Releases

The release tarballs contain pre-built firmware, emulators for windows and *nixes, documentation, and examples/demos of BASIC, C, and assembly programs.

Compilation

Sources

Note that to build the firmware, additional third-party sources are required. If not supplied, these will be downloaded automatically at build-time. These are not needed to build the emulators however. The automatic downloads, and the 'git' dependency may be avoided by collecting these sources manually.

• pico-sdk: https://github.com/raspberrypi/pico-sdk/releases
• tinyusb: https://github.com/hathach/tinyusb/releases
• PicoDVI: https://github.com/Wren6991/PicoDVI/archive/master.tar.gz
• pico-fatfs: https://github.com/carlk3/no-OS-FatFS-SD-SPI-RPi-Pico/releases

Then explode the tarballs and set the following variables in the environment:

$ export PICO_SDK_FETCH_FROM_GIT=OFF
$ export PICO_SDK_PATH=/path/to/picosdk_sources
$ export PICO_TINYUSB_PATH=/path/to/tinyusb_sources
$ export PICO_DVI_PATH=/path/to/picodvi_sources
$ export PICO_FATFS_PATH=/path/to/picofatfs_sources

Dependencies

• 'build-essential', 'base-devel', or equivalent (GCC for *nix binaries)
• 'x86_64-w64-mingw32-g++', or equivalent (GCC for windows binaries)
• 'gcc-arm-none-eabi' (GCC for ARM binaries)
• 'arm-none-eabi-newlib' (C stdlibs for bare-metal ARM target),
• '64tass' (6502 assembler)
• 'cmake'
• 'libsdl2-dev', 'sdl2', or equivalent (SDL2 development libraries)
• 'python3'
  • 'pillow'
  • 'gitpython'
  • 'pyserial' (not needed at build-time - optional for uploading files via serial port)

All of the sources and dependencies are freely available. Most distros have the dependencies packaged.
