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。
