## 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

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

* note

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

* update

```bash
  git pull
  git submodule update --init --recursive
  ```

* Add environment variables

```bash
  . add_path.sh
  ```
  * note

Don't forget `"."`

* Install toolchain

* K210

* Ubuntu/Debian/Kali

```bash
      wget https://www.kiterf.xyz/download/kendryte-toolchain-ubuntu-amd64-8.2.0-20190213.tar.gz
      tar zxvf kendryte-toolchain-ubuntu-amd64-8.2.0-20190213.tar.gz -C tools/K210/
      rm kendryte-toolchain-ubuntu-amd64-8.2.0-20190213.tar.gz
      ```
    
    * Arch

```bash
      wget https://www.kiterf.xyz/download/kendryte-toolchain-arch-amd64-8.2.0-20190415.tar.gz
      tar zxvf kendryte-toolchain-arch-amd64-8.2.0-20190415.tar.gz -C tools/K210/
      rm kendryte-toolchain-arch-amd64-8.2.0-20190415.tar.gz
      ```

* ESP32

* Ubuntu/Debian/Kali/Arch

```bash
      cd tools/ESP32/esp-idf
      ./install.sh
      cd $KITERF_PATH
      ```

* ESP8266

KiteRF also integrates the ESP8266 development environment, which is not necessary, and you can choose to ignore it.

* Ubuntu/Debian/Kali/Arch

```bash
      wget https://www.kiterf.xyz/download/xtensa-lx106-elf-linux64-1.22.0-92-g8facf4c-5.2.0.tar.gz
