Program for Section 9 in October. 2014 issue of the Transistor Gijutsu
(Japanese electronics magazine)
概要
このプログラムは、ソフトウエアDDSにより、任意の波形を出力(2ch)します。 特徴は次のとおりです。
- PWM出力をDAコンバータとして利用します。
- 周波数や波形、バースト条件などを個別に設定できる独立した出力を2チャネル持っています。
- 周波数分解能0.023mHz
- 周波数範囲0.023mHz~10kHz
- 各チャネルにそれぞれ、波形の先頭で出力されるトリガ出力があります。
- 出力波形を関数で定義できます。
- 休止波数、出力波数、を設定することでバースト波形が出力できます。
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。
- DDS.cpp - DDSによる波形発生
- 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。
