stm32版si5351a VFO周波数校正
スケッチ
機能が含まれたスケッチは、JA2GQP's Download siteのstm32フォルダにあるstm32_si5351a.zipファイル。si5351a2.hは、水晶発振子の基本周波数を変数 xtalFreq が定義されているので、zipファイルに含まれたファイルを使う。2017年11月2日木曜日
7.2MHz Knobless Wonder Filter
試験した回路図である。7.2MHz以下に収める必要があるので、多少余裕を見てこの定数とした。試験回路をユニバーサル基板で作った。
cf（中心周波数） 7.1979MHz
cp（LSBキャリアポイント）7.1990MHz
試作した結果から、7.2MHzの水晶発振子をフィルタとして使える。ただし、最終的な回路を組み立て、実機検証する必要がある。
参考データ
今後の課題
ユニバーサル基板で試作した為、リード線の浮遊容量が大きい。この回路方式の場合、浮遊インダクタンスの影響を大きく受けるので、最終的な姿で回路定数を決め検証する。2017年9月16日土曜日
stm32 si5351a VFO(With BFO)
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。///////////////////////////////////////////////////////////////////////////////////

スケッチ
si5351a2.hは、本来、スケッチと同じフォルダに入れるが、srcフルダに入れ階層的にした。PLL発振出力は clk0 1chのみである。デフォルト周波数は、50.6MHzとし、STEPは10kHz刻みにした。受信機はダブルスーパ（IF=10.7MHz）を想定したので、条件が異なれば修正が必要。メモリー保存は、AD7C方式を採用した。また、周波数補正は、si5351a2.hの41行目XTAL_FREQ 25000000を実周波数（カウンターなどで測定した値）に書換えれば良い。///////////////////////////////////////////////////////////////////
