M5Core2 で ATEM スイッチャーを作ってみた (※M5Core2ライブラリ ver.0.0.6へ対応)

Last updated at Posted at 2021-01-17

はじめに

M5Core2 で ATEM Mini Pro を操作するスイッチャーを作ってみました。

操作している様子(動画)

https://youtu.be/5ASHgIHe9pQ

これまでは ATEM Mini Pro はボタン (入力ソース) が 4 つで、M5Stack はボタンが 3 つしかなかったので、用途が限定されていました (例えば、ボタンは一部の Program と Preview の切替のみ、液晶画面はタリーライトとして表示、など) が、M5Core2 は液晶画面がタッチパネルとなり、従来のボタンもタッチパネルの一部として認識されます。また、液晶も TFT から IPS へ変更されたため、視野角も広く表示もクリアです。

ATEM スイッチャーの画面・ボタン配置

液晶画面には入力ソースのボタン (タリーライト) を表示し、タッチパネルで Program (上段) と Preview (下段) を切り替えられるようにしました。
また、従来のボタン (ボタンA と ボタンB) は Program と Preview の入れ替え (AUTO と CUT) に割り当てました。

準備

1. Arduino IDE

開発環境となる Arduino IDE をインストールします。

2. ボードマネジャー

M5 公式の手順通り、ボードマネジャーから M5stack を選択してインストールします。(2021年9月5日時点のバージョンは 1.0.9 でした)

3. M5Core2 ライブラリ

M5 公式の手順通り、ライブラリを管理から M5Core2 を選択してインストールします。(2021年9月5日時点のバージョンは 0.0.6 でした)

4. ATEM ライブラリ

ネットワーク経由で ATEM Mini Pro を操作する際に BMD (Black Magic Design) というプロトコルが使用されています。
http://skaarhoj.com/fileadmin/BMDPROTOCOL.html
SKAARHOJ さんが公開されている Arduino 用のライブラリを使用 (一部、コードを修正してインストール) します。
https://github.com/kasperskaarhoj/SKAARHOJ-Open-Engineering
必要なライブラリは以下の 4 つです。

  • ATEMbase
  • ATEMmax
  • ATEMstd
  • SkaarhojPgmspace

修正内容

修正箇所は ATEMbase ライブラリの 3 箇所です。

  • ATEMbase.cpp (1 箇所)
  • ATEMbase.h (2 箇所)

理由は Arduino Ethernet Shield と ESP8266 とで条件付きコンパイルされるためで、M5Core2 は ESP32 が使用されているため、修正が必要になります。

修正前
#ifdef ESP8266        
WiFiUDP Udp;
#else
EthernetUDP Udp;
#endif
修正後
WiFiUDP Udp;

修正済のソースコードを github に置きました。
https://github.com/kitazaki/M5Core2_atemswitcher/raw/main/ArduinoLibs.zip

コード

ソースコードを github に置きました。
https://github.com/kitazaki/M5Core2_atemswitcher

使用する環境に合わせて、Wi-Fi (SSIDとパスワード) と ATEM Mini Pro (IPアドレス) の設定をする必要があります。

IPAddress switcherIp(0, 0, 0, 0);
const char* ssid = "";  // Wi-Fi SSID
const char* password =  "";  // Wi-Fi Password
