Tetsuki 0:470a92800884 5 回路が新しくなり、AnalogOutから電圧が出力できるようになった。これを受けて出力場所の変更を行う。
Tetsuki 0:470a92800884 6 これに伴いプログラムを一新することにした。
Tetsuki 0:470a92800884 7 p18に0~1の出力を行うとそれが0~570Vとして出力できる。
Tetsuki 0:470a92800884 8 p14~p17で電圧、周波数を10V/Hzずつ変更するようにした。
Tetsuki 0:470a92800884 9 電圧周波数の初期値は570V/100Hz
Tetsuki 0:470a92800884 10
Tetsuki 0:470a92800884 11 黄色：電圧10V上昇
Tetsuki 0:470a92800884 12 青色：電圧10V下降
Tetsuki 0:470a92800884 13 白色：周波数10Hz上昇
Tetsuki 0:470a92800884 14 黒色：周波数10Hz下降

Tetsuki 0:470a92800884 20 電圧値・周波数を確認できるようにした。(要Teraterm)
