JA2GQP’s　Blog: 9月 2017

このVFOは、JA2NKD OMのマルチバンドVFO にBFOを付加した物で、stm32F103c8t6＋si5351aで構成している。特徴は、BFOが簡単に変更出来る様にした事と、光学エンコーダの採用でアナログ感覚のVFO操作である。BFO変更は、Modeスイッチを長押し(約１秒間スイッチを押す）エンコーダで周波数を調整後、再び、Modeスイッチを長押し(約１秒間）で書換を行う。

光学エンコーダは、中華製400P/R($10位)を使ったため、エンコーダのコントロールSTEPは、1Hz、10Hz、100Hzにした。

回路図である。光学エンコーダの電源は省略してある。stm32への書込みは、シリアルとした。理由は、省メモリとシリアルモニタが使える環境にした。開発環境にST-LINK V2を使った場合、I/O割付に制限がある様なので変更（9/17）した。

スケッチ

JA2NKD OMのオリジナルVFOは、max 8 Bandであるが6 Bandに変更している。VFO周波数は、周波数変化が2秒以上なければ、疑似EEPROMに保存する機能を追加した。si5351a2.hは、オリジナルの物を使っている。ただ、Ucglib.hは私のPC環境で複数のライブラリが参照されるため、参照場所の明確化をした。スケッチと関係ファイルは、download siteのstm32フォルダからダウンロード可能。
