操作
・EEPROM初期化
STEP SWを押しながら、電源onして”ーー．－－－．－－” が表示されるまでSTEP SWを押していると、EEPROMの初期化が行われる。
・VFOモード（上の写真は、チャンネルモード）
STEP SWを長押しすると、VFOモードからチャンネルモード、または、チャンネルモードからVFOモードに変わる。
・チャンネル書き換え
チャンネルモードの時、RIT SWを長押しし、VFOモードを表示させ希望の周波数に変更する。再び、RIT SWを長押しするとチャンネルモードに表示が変わり、変更されたチャンネルデータで表示される。書き換え可能なチャンネルは、”０”、”９”のみである。チャンネル”１”から”８”は指定周波数なので書き換え不可。
回路図
スケッチ
コンパイルする時、必要に応じマーカ部分の変更をする。
・RX_IF = 455000 受信時のオフセット。初期値 455000（+455kHz）
・TX_IF = 0 送信時のオフセット。初期値 0
・Int_End = 49 プログラムからの初期化を行う時の、初期化終了判断コード。
残っている前回データをクリアして、新しい初期値をセットしたいときに使う。前回の判断コードと同じ場合は、初期化されないので注意。

if for vfo only, what should be changed?
返信削除(no Ch).
Thanks
From the si5351 VFO folder on the download site
返信削除Download oled_50MHz_AM.zip.
It is a mono band VFO. I think that would be helpful.
