ESP32-WROOM-32Dを使ってみたい

こんにちは かなで です。

ESP32-WROOM-32Dをご存じですか?(たぶんご存じの方しか見ることがないページだと思いますが)

ATmega328PU単体動作でいろいろ遊んでいた今日この頃ですが、上の写真の機器を使ってWifi通信をしてみたいと思い、購入してみました。

ひとつずつ段階を追っていこうと思うので、まずはLチカ相当をやってみようと思います。(本記事は準備だけ)

Arduino IDE設定

まだダウンロード&インストールしていない方はこちら↓

インストールされている場合は、「ファイル」→「環境設定」をクリック

追加のボードマネージャのURL欄に「https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json」を入力し、「OK」を押します。

サイト様によっては「https://dl.espressif.com/dl/package_esp32_index.json」を入力するようになっていますが、上の方が最新のようです。(一応比較すると上の方が純粋に増えてるだけでした)

マイ備忘録を兼ねているので、URLが使えなくなったとき用に以下にjsonファイルの中身を記載しておきます。

グググッと飛ばしてください。

続きです。

「ツール」→「ボード:***(任意)」→「ボードマネージャ…」とクリックします。

ボードマネージャが開くので「esp32」と入力すると、「esp32 by Espressif Systems」というのが表示されます。

カーソルを合わせると、プルダウンでバージョン選択と「インストール」のボタンの表示されます。

現時点の最新は2.0.3みたいなので、2.0.3を選択し、インストールを押します。

ステータスバーが徐々に増えていきます。

思いのほか大量にダウンロードしてるみたいです。

終わるとこの画面になりました。バージョン2.0.3 INSTALLEDとなっていますのでこれで閉じます。

再度「ツール」→「ボード」と進むと、「ESP32 Arduino」が増えていることを確認します。

続けて「ESP32 Arduino」の中の「ESP32 Dev Module」を選択します。

すると、ツールの中にやたらと大量に項目が増えてしまいましたが、これで正解のようです。

ちなみに「ボード」→「Arduino AVR Boards」→「Arduino Uno」と選べば、元に戻ります。

参考:元の状態↓

Lチカは次回ですね(汗
