s-meterは、イメージデータをimage2cppでモノクロデータにして加工した。カラー表示を行うので有れば、同様なツールとしてlcd-image-converterがある。これらのツールを使えば、簡単にデータ化できる。
周波数表示に使ったフォントは、デジタル風ものを選んだが、等幅フォントでない。この為、1文字毎にロケーションを指定している。
VFOの機能は、オートモード、RIT、自動メモリー保存、バンド範囲チェックなど 際立った機能は無いが実用的に仕上がった。
回路図
DIOにTX/RXまで使っており、拡張性が無いように見えるかも知れないが、必要な機能が達成できれば、それで良い。

esp8266は曲者
開発にArduino IDEを使ったが、esp8266(WeMos mini D1)は個性的な印象だ。DIOすら制限があり、この割付がベストだと思っている。esp8266には、産業用コントローラなどで使っているウォッチドグタイマー装備されおり、トラブル時の対策を悩ませる一員となった。スケッチ
