Initial Setup

1. Run the setup script. This will set up git submodules and prompt to install missing packages.

   1. ./scripts/setup

2. To install Radiant you can try to run directly from CLI the extracted binary. In some cases this may fail with “Floating point exception.” error.

   In that case run: `./2.2.0.97.3_Radiant_lin.run --console --prefix ~/lscc/radiant/2.2`
   
   Analogously for any update binaries available.
   

   2. Set RADIANT_DIR to the path where it is installed. e.g. in your .bashrc, you might add:
      1. export RADIANT_DIR=$HOME/lscc/radiant/2.2/bin/lin64
   3. Run sudo ~/lscc/radiant/2.2/programmer/data/vmdata/udevsetup_ubuntu (or one of the other udevsetup scripts) to correctly configure USB subsystem for Radiant.

Editing code

If your editor has IDE features for Python (e.g. vscode with the Python extension installed), then you should open it with the appropriate environment variables set. e.g.:

(source environment; code .)
