ロジックアナライザ

ESP8266で E-ink を表示させるために、信号解析用のロジックアナライザーが必要になりそうなので、安いものを探しました。

以前、Logic Pirate （とLogic Snifferで動作）というのを知りましたが、

Logic Pirate というオープンソースのロジックアナライザ

ハードが4500円（30ドル＋送料）ほどで、もう少し安いのはないかと調査すると、ありました。世の中は本当に広いものです。

EZ-USB FX2LP CY7C68013A USB Development Board Core Board Logic Analyzer

これはaliexpress で1000円以下で売っています。ソフトウェアは、sigrok というオープンソースがあります。ということで、ポチっておきました。年末に来るといいな。

追記：EZ-USB FX2LPでアリエクを検索すると、たくさんでてきます。2021年2月時点で、537円になっていました。

追記：とても良い映像コンテンツがあったので貼っておきます。@OpenTechLabChan さんのチャンネルです。

Windows はバイナリがあり、osx は brew で入れるようで、試してみましたが、インストールに失敗するようで、そのメモです。windows バイナリ版は起動し、以下のようにデモ信号を見れます。最初の一台としては十分な機能のような気がします。

sigrok を osx で動作させるため、以下を参考。

http://sigrok.org/wiki/Mac_OS_X

以下の流れですが、★でこけます。

1) $ brew tap rene-dev/sigrok
2) $ brew install python3
3) $ brew install –HEAD libserialport
★4) $ brew install –HEAD –with-libserialport libsigrok
5) $ brew install –HEAD libsigrokdecode
6) $ brew install –HEAD –with-libserialport sigrok-cli
7) $ brew install –HEAD pulseview
8) $ brew install sigrok-cli

ファームウェアは、以下のようです。

Building manually の手順でやればいいのかもですが、osx のバイナリもだれか作っているはずで、探したらありました。また実機が着たらゆっくり料理することにし、今はソフトウェアの動作だけ確認しておきます。

ちょっとバージョンは古いようですが、osx でも動作するようです。

ドラッグでタイムラインの移動、マウスホイールで信号の拡大縮小できるインターフェイスです。各種信号解析も可能なようです。デジタルは8チャンネル入るようですので、これで十分用は足せそうです。DHT の温度センサーのデータ解析もあるようです。自分にはこれで十分だと思います。サポートするハードウェアはかなりたくさんあって、迷います。とりあえず、8チャンネル取れるもので、安いものを選びました。

Open Workbench Logic Sniffer というのも、良さそうです。

その後、マニュアルビルドを試すも、libsigrok のmake で失敗。以下次回再開するときのメモ。

    Alternatively, you may set the environment variables SIGROK_CLI_CFLAGS
