概要
公式ドキュメント通りだとPythonのバージョンが違ってエラーが出たので仮想管理環境下でEPS 32 IDFをインストールする。
環境
- macOS Sierra 10.12.6
- ESP IDF 3.0-rc1
- ESPr Developer 32
手順
-
仮想環境管理設定
$ mkdir -p ~/esp $ cd ~/esp $ python3 -m venv -python=/usr/local/bin/python2.7 myvenv $ source myvenv/bin/activate (myvenv) ~$ pip install pyserial Collecting pyserial Downloading pyserial-3.4-py2.py3-none-any.whl (193kB) 100% |████████████████████████████████| 194kB 520kB/s Installing collected packages: pyserial Successfully installed pyserial-3.4 You are using pip version 8.1.1, however version 9.0.1 is available. You should consider upgrading via the 'pip install --upgrade pip' command. -
Toolchainインストール
Toolchainは頻繁に更新されますので最新版を参照。(myvenv) ~$ tar -xzf ~/Downloads/xtensa-esp32-elf-osx-1.22.0-73-ge28a011-5.2.0.tar.gz (myvenv) ~$ export PATH=$PATH:$HOME/esp/xtensa-esp32-elf/bin (myvenv) ~$ echo 'export PATH=$PATH:$HOME/esp/xtensa-esp32-elf/bin' >> ~/.bash_profile (myvenv) ~$ git clone --recursive https://github.com/espressif/esp-idf.git (myvenv) ~$ export IDF_PATH=~/esp/esp-idf (myvenv) ~$ echo 'export IDF_PATH=~/esp/esp-idf' >> ~/.bash_profile ESPr Developer 32をMacにUSBで接続
-
サンプルプログラムをコピー
(myvenv) ~$ cd ~/esp (myvenv) ~$ cp -r $IDF_PATH/examples/get-started/hello_world . -
Portを調べる
/dev/cu.usbserial-で始まるのがESPr Developer 32が接続されているポート。(myvenv) ~$ ls /dev/cu.* /dev/cu.Bluetooth-Incoming-Port /dev/cu.usbserial-DN01EAI5 -
ポートを設定
(myvenv) ~$ cd ~/esp/hello_world (myvenv) ~$ make menuconfig- Serial flasher config > Default serial portと辿り、5.で調べたポートを設定する。
- 終わったらSave。
