それで，週に一度くらい窓辺に置いて同期しますが，１か月くらい忘れることもしばしばですし，夏場の窓辺は高温になるのであまり時計に良くないです．<\/p>\n\n\n\n
最近SNSのお仲間がM5ATOM Liteと専用基板を組み合わせた疑似JJY発信機を紹介してくださったので，早速真似しました．どちらもスイッチサイエンス<\/a>から買えます．<\/p>\n\n\n\n ハードウェアは特に組み立てるというレベルの話ではなく，ピンヘッダーを合わせて差し込むだけです．<\/p>\n\n\n\n ソフトは結構手こずりました．Arduinoはかなり昔に少しいじりましたが，すっかりご無沙汰です．最初macOS用のArduino IDEをダウンロードして，ドライバーが要るとか要らないとか言うのでM5StackのサイトからCP210x用のドライバーをダウンロードしましたがどうもこれは違うようです．<\/p>\n\n\n\n 次に一番得意なSlackware64に移り，どうもCP-210xでなく，FTDIのドライバー1<\/a><\/sup>Linux Kernel driverでは，ftdi_sio.ko．<\/span>と当たりをつけ，とりあえずUSBポートにM5ATOM Liteを差し込むとKernel moduleがロードされUSBポートとして見えました．<\/p>\n\n\n\n ここまではそれほど時間はかかりませんでしたが，ここから先が長くて，シリアルポートは認識されましたが，なかなかボードが認識できません．というか，ボードのリストにM5Stackのシリーズが表示されません．あっちのPC，こっちのOSと移りいろいろためしました．<\/p>\n\n\n\n これは結局，ボードマネージャーにesp32<\/strong>を追加する必要がありました2<\/a><\/sup>“M5なんとか” ではないんです😅<\/span>．ようやくそれがわかって最終的にmacOSでSketchを書き込み，動作させることができました3<\/a><\/sup>Mac miniにはFTDIのUSBシリアルコンバータを2つつないで使っているので，敢えてドライバーの追加は不要ということが試行錯誤の過程で解りました．<\/span>．<\/p>\n\n\n\n 昨夜仕掛けて朝の段階で，電波を受信して同期しているマークが表示されています．<\/p>\n\n\n 余談ですが，あっちのPCこっちのOSと移っている間に久しぶりにWindows 10 (32bit)も起動してみました．そしたら，Google Driveがもはや32bitはサポートしていないよと言って，自らをuninstallしてしまいました．また肝心なArduino IDEも32bit版はありませんでした．もう32bit OSは使えないですね．<\/p>\n","protected":false},"excerpt":{"rendered":"
