How to use

You can follow the steps below to set up the development environment, or directly download the release version of the full environment.

• clone

  git clone --recursive https://github.com/ATmega8/kiterf
  cd kiterf

  • note

  Don't omit --recursive, because we use submodule.

• update

  git pull
  git submodule update --init --recursive

• Add environment variables

  . add_path.sh

  • note

  Don't forget "."

• Install toolchain

  • K210
