Program for Section 8 in October. 2014 issue of the Transistor Gijutsu
(Japanese electronics magazine)
概要
このプログラムは、サーミスタの抵抗値変化をAD7714(24bitADC)で測定し、抵抗値を温度値に変換することで、0.001℃程度の分解能で温度変化を測定します。
ファイル
このソフトウエアは、次のファイルから構成されています。
- AD7714.cpp - AD7714の内部レジスタを設定
- Thermistor.cpp - サーミスタの抵抗値から温度値に変換
- ExpAvr.cpp - 指数平均によるソフトウエアＬＰＦ
- main.cpp - main()関数
詳細については、10月号の記事および上記ファイル中のコメントを参照してください。
